Check for common causes of Skype for Business Online sign-in errors
Most sign-in issues can be traced to a small number of causes, and many of these are easy to correct. The table below lists some common causes of sign-in errors and some steps you or the users can take to resolve them.
| Possible Cause | Resolution |
|---|---|
| During sign-in, a dialog box appears that contains the following phrase: cannot verify that the server is trusted for your sign-in address. Connect anyway? | Verify that the domain name in the dialog box is a trusted server in your organization—for example, domainName.contoso.com. Ask the user to select the Always trust this server check box, and then click Connect. Enterprise customers can prevent this message from appearing when a user signs in for the first time by modifying the Windows registry on each user's computer. For details, see Modify TrustModelData registry keys. |
| Mistyped sign-in address, user name, or password | Confirm that the user's sign-in name and password are correct. Verify that the user's sign-in name is formatted as follows: bobk@contoso.com. This may be different from the format you use to sign in to your organization's network. Ask the user to try signing in again. |
| Forgotten password | Reset the user's password and notify him or her of the new temporary password. |
| Not licensed to use Skype for Business Online | Confirm that the user is registered as a Skype for Business Online user. If not, register the user, and then ask him or her to sign in again. |
| Wrong version of Skype for Business Online installed | This issue is usually associated with an error message that contains the following phrase: the authentication service may be incompatible with this version of the program. Ask the user to uninstall and reinstall Skype for Business Online from the Microsoft 365 admin center. |
| Problem acquiring a personal certificate that is required to sign in | If the user's sign-in address has recently changed, they may need to delete cached sign-in data. Ask users to sign out, click the Delete my sign-in info link on the sign-in screen, and then try again. |
| You set up a custom domain name, and the changes may not have finished propagating through the system. | First, ensure that you have modified the Domain Name Service (DNS) records to reflect the change. If you have already made the necessary DNS changes, advise the user to try logging in later. DNS changes can take up to 72 hours to be reflected throughout the system. |
| System clock out of sync with server clock | Ensure that your network domain controller is synchronizing with a reliable external time source. For details, see the Microsoft Knowledge Base article 816042, How to configure an authoritative time server in Windows Server. |
To troubleshoot Skype for Business Online sign-in errors, start by eliminating the most common causes of sign-in difficulty. If necessary, you can then follow specific resolution steps based on the type of error. If the user still cannot sign in, collect additional information, and then seek additional help.
Follow resolution steps for a specific error (Enterprise only)
Important
These instructions are intended primarily for Microsoft Office 365 Plan E customers. If you are an Office 365 Plan P customer, continue to the following section, Collect more information and seek additional help.
If the user cannot sign in after you have tried the suggestions in the previous section, then you can do additional troubleshooting based on the type of error. The table below lists the most common error messages and possible causes. Following the table are detailed procedures to address each issue.
| Error message | Possible cause | Resolution |
|---|---|---|
| Sign-in address not found | Sign-in requests from the Microsoft Online Services Sign-On Assistant (msoidsvc.exe) are not going through your external firewall, or proxy server. | Add a firewall entry for msoidsvc.exe to your proxy server |
| Server is temporarily unavailable | If your organization has a custom domain, the necessary Domain Name System (DNS) settings may be missing or incorrect. | Update DNS settings |
| Server is temporarily unavailable | If your organization is using single sign-on with Active Directory Federation Services (ADFS), you may have used a self-signed Secure Socket Layer (SSL) certificate rather than one from a third-party certification authority. | Install a third-party SSL certificate on your ADFS server |
| Problem acquiring a personal certificate that is required to sign in | If you've already removed the cached server data used to sign in and the error continues to appear, the user's security credentials may be corrupted, or an RSA folder on the user's computer may be blocking authentication. | Update security credentials |
| A certificate trust dialog box appears when a user signs in for the first time. | This dialog box appears if your Skype for Business server is not yet listed in the TrustModelData registry key. | Modify TrustModelData registry keys |
| User is not SIP enabled | If your organization had a previous installation of Microsoft Office Communications Server or Microsoft Lync Server 2010, you may not have deleted your users from the server before decommissioning it. As a result, the msRTCSIP-UserEnabled attribute is still set to FALSE in Active Directory Domain Services. | Update user settings in Active Directory |

Obtain an SSL certificate from a third-party certification authority such as VeriSign or Thawte.
Install the certificate on your ADFS server by using the ADFS management console.
Update security credentials
This procedure is a possible fix for the error message Problem acquiring a personal certificate required to sign in. Keygen zbrush 4r7.
To eliminate possible certificate or credential problems, first renew the user's certificate in Windows Certificate Manager. To do this, follow these steps:
Open Windows Certificate Manager. To do this, click Start, click Run, type certmgr.msc, and then click OK.
Double-click Personal, and then double-click Certificates.
Sort by the Issued By column, and then look for a certificate that is issued by Communications Server.
Right-click the certificate, and then click Delete.
Next, if the user is running Windows 7, remove their stored credentials in Windows Credential Manager. To do this, follow these steps:
Click Start, click Control Panel, and then click Credential Manager.
Locate the set of credentials that is used to connect to Skype for Business Online.
Expand the set of credentials, and then click Remove from Vault.
Sign in again and reenter the user's credentials.
Finally, if the user still cannot sign in after you've updated their credentials, try deleting the RSA folder on the user's computer, because it could be blocking completion of the user authentication process:
Sign in to the user's computer using an administrator account.
If necessary, turn on the folder view option Show hidden files.
Type the following into the address bar of File Explorer: C:Documents and SettingsUserNameApplication DataMicrosoftCryptoRSA, where UserName is your Windows sign-in name.
Delete any folder that begins with the name S-1-5-21- followed by a string of numbers.
Modify TrustModelData registry keys
When a user signs in for the first time, they may receive a dialog box that contains something like the following: Cannot verify that the server is trusted for your sign-in address. Connect anyway? This is a security feature, and not an error. However, you can prevent the dialog box from appearing by using a Group Policy Object (GPO) to update users' machines with your domain name before they sign in for the first time. To accomplish this, do the following:
- Create and deploy a GPO that appends your Skype for Business domain name—for example, domainName.contoso.com—to the current value of HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftCommunicatorTrustModelData.
Important
You must append your domain name to the existing value, not simply replace it.
For details, see the Microsoft Knowledge Base article 2531068, Skype for Business (Lync) cannot verify that the server is trusted for your sign-in address.
Update user settings in Active Directory
If your organization had a previous installation of Microsoft Office Communications Server or Microsoft Lync Server 2010, you may not have deleted your users from the server before decommissioning it. As a result, the msRTCSIP-UserEnabled attribute is still set to FALSE in Active Directory Domain Services.
To fix this issue, follow these steps:
Update the msRTCSIP-UserEnabled attribute for all affected users to TRUE.
Rerun the Microsoft Online Services Directory Synchronization Tool (DirSync). For details, see AIntegrate your on-premises directories with Azure Active Directory.

Skype for Business is one of the primary communication channels within a corporate environment. It can impact company productivity if it’s not working properly. Skype for Business desktop clients connect to the server through many components and several configuration settings. In this article, we’ll look at what needs to be done to fix authentication (connection) issues.
Learn why you would start reselling Microsoft Teams sooner than later with our webinar
Why Can’t Your Tenants Log Into Skype for Business?
Office 365 offers a Single Sign ON (SSO) as part of the ADFS (Active Directory Federation Service). It connects the Active Directory with Office 365 and provides users with a single sign-on for Office 365 services on desktops and mobile devices.
Single Sign-On essentially provides a generic single sign-on solution by storing and transmitting encrypted user credentials across the network boundaries. Therefore end users do not have to sign in (and remember different credentials) each time they log in to a different environment/application. (Outlook, Skype, OneDrive etc).
In order to do that, it uses the Office 365 credentials previously cached in the Windows Credentials manager. More on that later.
SSO is also capable of Office 365 provisioning; it offers Security Compliance, license pairing, Multi-factor Authentication and it is fast.
Office 365 brings these three main identity models to set up and manage user accounts:
Cloud identity, Synchronized identity, and Federated identity.
The Federated Identity model brings with it Single Sign On capabilities.
Users working for big organizations, for instance, would most probably use an Office 365 implementation based on Federate Identity, and on the process to migrate from an on-premises infrastructure (Local Servers, NOT cloud servers) to the MS cloud solution (Office 365).
The problem arises when locally cached passwords don’t match.
Office 365 (SSO) caches the access password on the Windows credential manager while the browser will cache it in itself. Moreover, corporate environments very often require a password change, which means that password changes will also occur in Active Directory, and there will be collateral issues due to password replication disruption or latency.
Has been noticed that a mismatch between the credentials stored by those components, won’t allow an SSO connect to its O365 server.
To fix this, one needs to clear all the credentials data previously cached locally on the machine and try to log in again using the latest available credentials (ID plus Password).

How to Troubleshoot Skype for Business Login
Skype For Business Mac We Couldn 27t Sign You Into Something
1) Internet Explorer: Clear the Cache
(The same applies when using different browsers)
On Internet Explorer, click on the 3 dots in the upper right and go to Settings.
Clear Browser data, click on: Choose what to clear.
Select all the checkboxes and click on Clear.
2) Windows Credential Manager: Clear the Stored Passwords
Windows Credential manager is a tool that allows a user to store names and passwords used to login to any websites or to the network.
Credentials are saved in a special folder called Vaults. This data is then used by Windows itself or other applications, such as Windows Explorer, Office 365, Internet Explorer, and a few others when running the authentication processes.
Go to start. In the search box, type: Credential manager.
Open it.
Expand each password field, and remove the stored password by clicking on Remove.
Repeat the process for each stored password.
3) Sign Out From Skype and Click On Delete My Sign in Info
4) Verify the Proxy Auto Configuration
The Proxy Auto Config (PAC) setup defines how web browsers and other user agents (like Skype) can automatically choose the proxy server assigned to them. The PAC configuration is one primary network check that we need to perform in order to ensure that we are compliant with the corporate network policies and configurations.
Open Internet Explorer, Tools >> Internet Options >> Connections >> Lan Settings >> verify PAC configuration:
If everything is OK, (check if your network infrastructure relies on a proxy server) we can exclude the PAC configuration as the root cause and proceed with troubleshooting.
5) Clear the DNS Cache
The DNS cache stores the IP addresses of the servers containing web pages and services you have recently used. If the server IP address changes before the entry is stored in the DNS cache, the access is no longer allowed on the server.
Go to Start. On the search box type: cmd.
Open it.
Type: ipconfig /flushdns, and press Enter.
6) Make Sure Cookies Are Not Blocked On Your Browser
On Internet Explorer, click on the 3 dots on the upper right and go to Settings.
Go to: Advanced Settings.
Make sure the Cookies status is set on: Don’t block cookies.
Close Internet Explorer.
7) Check Your Firewall Settings
There may be a firewall blocking your access to Skype.
Quit Skype.
Click Start > Control Panel and double-click Windows Firewall.
Ensure that Don’t allow exceptions is unticked.
Go to the Exception tab, and check if Skype is included among the exceptions:
In this case, if Skype is displayed in the Programs and Services list, highlight it and click Delete.
Click Yes and OK.
Sign into Skype again. If the Windows Firewall asks to block Skype, click Unblock.
8) Clear the SIP Profile
The SIP Profile contains the configuration and user data for the corresponding Skype Connect™ service.
Go to C:Usersuser$AppDataLocalMicrosoftOffice15.0Lync
Delete the Folder: sip_user@domain.com
Restart your pc and see if you can now access Skype correctly.
If the issue persists, do the following.
9) Repair the Office 365 Pack
Click Start > Control Panel > Programs > Programs and Features.
Select the Office Pack you want to repair, and then click Change.
Click either on Quick Repair or Online Repair.
Restart your pc and see if Skype can now be accessed correctly.
10) Verify the Lyncdiscover CNAME Record
The Lyncdiscover CNAME is a parameter present in the Domain Name System (DNS) records. One needs to verify that is properly registered.
Go to: https://www.testlyncconnectivity.com/
Select the test you want to run (SfB/ Lync) and select the first option: Skype for Business Server Remote Connectivity test.
Provide your Office 365 credentials and start the test.
If any issues are detected, check your DNS configuration settings.
Check the Office 365 Health Status Portal
Last but not least, remember: Always keep an eye on the Office 365 Health Status Portal.
Why? These are the 2 reasons:
- Avoid wasting your (and your user’s) time: The Health Status Portal gives you the overview of any general issue going on the Office cloud platform. If for instance, maintenance is being run on the Server mail-flow performances, you’ll know that before the user calls in reporting he is not receiving his emails on time. It will be enough to provide the user with such information and kindly ask to wait a while. No remote troubleshooting sessions will, therefore, be necessary.
- The daily interaction with the Health Status Portal will give you more confidence and know-how in approaching any Office 365 issue.
Sign in with your Office 365 admin account at https://login.microsoftonline.com
In the Office 365 admin center, go to Health > Service health.
The site provides information about the known issues and maintenance activities in progress by Microsoft for each Office 365 environment. It’s a good habit to always keep it at hand, since it might spare you long (and worthless) troubleshooting sessions on Skype for Business trying to pinpoint a problem that is actually taking place at the server level.
