How to Troubleshoot Skype Sign-in Loop Issues

If you're experiencing a Skype sign-in loop, where Lync continuously prompts you for your credentials even after you've signed in multiple times, there's likely an issue with Outlook or the Exchange services. This issue can occur due to various reasons and may be expected behavior in certain scenarios.

When Lync prompts you for your credentials, it's usually because it needs to connect to an external service such as Microsoft Exchange Free/Busy or the Exchange Calendar service. In these cases, you're required to enter your login credentials again to grant Lync access to these services.

There are several reasons why this issue might occur, including problems with Outlook or the Exchange services. To troubleshoot this issue, it's essential to identify the cause of the problem and take steps to resolve it.

One common reason for the Skype sign-in loop is a problem with the Calendar and Free/Busy information from Outlook. When Lync tries to connect to these services, you may be prompted for your credentials again. The message you receive will vary depending on which service Lync is trying to connect to.

To resolve this issue, you can try restarting your Outlook application or checking the Exchange services for any issues that might be causing the problem. You may also need to adjust your Outlook settings to allow Lync to access these services seamlessly.

By following these troubleshooting steps and identifying the root cause of the issue, you should be able to resolve the Skype sign-in loop and enjoy a seamless communication experience with your contacts.
