How to fix “Sorry, you need to sign out of Teams and sign in again” error

Microsoft Outlook offers a feature called add-ins, which are applications that provide additional functionalities within Outlook. One such add-in is Microsoft Teams, which is available to Microsoft 365 users and can be enabled to schedule Teams meetings directly from Outlook on your Windows 10 or Windows 11 PC. If you’re having trouble scheduling Teams meetings in Outlook and receive an error message saying, “Sorry, you’ll need to sign out of Teams and back in again,” follow the steps below.

Step by step process: How to fix “Sorry, you need to sign out of Teams and sign in again” error (Classic Outlook)

  • First, open Outlook on your desktop.
  • In Classic Outlook, go to “file” in the menu at the top.
  • Then head to “Options.”
  • In Options, click on “Add ins.”
  • Next, select “Manage COM Add-ins” in the dropdown box next to “Manage.”
  • Click “Go.”
  • Uncheck the option that says “Microsoft Teams Meeting Add-In for Microsoft Office.”
  • Finally, click “OK” to save.

If your business requires it, you must first sign in to Microsoft Teams using Multi-Factor Authentication (MFA). After you’ve successfully signed in to Teams, the Outlook add-in should function. If it doesn’t, consider deleting Temp files, which may be corrupted and preventing Teams from functioning normally.

In a single day, your Windows operating system and numerous third-party apps generate hundreds of temporary files on your computer. Normally, these files aren’t a problem, but as their number grows, they clog up valuable hard disk space and slow down your system’s overall performance.

You can free up a lot of disk space and keep your system running at optimal performance by removing all such cache files. On Windows 10 and Windows 11, there are several options for deleting temporary files. Continue reading to learn more about them.

Steps to Remove Temporary Files and Fix Teams Errors

If you continue to receive the “Sorry, you need to sign out of Teams and sign in again” error despite temporarily removing the add-in, it may be due to a corrupted file or a security issue. Another method to try is removing temporary files, which can help clear errors within Microsoft Teams.

Temporary files are used by Windows to assist the operating system in performing its tasks and speeding up the system. These cache files might become damaged, causing performance issues in some applications. The first thing you should do if you’re running out of storage space or observe any strange behavior from an application is to remove the system temp files.

Temporary files are created by software that works with large volumes of data, such as graphics, video, or media editing applications. These generated temporary files are frequently left behind even after the job is completed, resulting in wasted disk space.

Step-by-Step Process to Delete Temporary Files

  • Open File Explorer:
    • Press Windows + E to open File Explorer.
  • Navigate to the Temp Folder:
    • Go to > Local Disk (C:) > Windows > Temp.
  • Delete Temp Content:
    • Select all files in the Temp folder (Ctrl + A) and delete them (Shift + Delete to permanently delete).

Additional Methods

Programs also generate temporary files for backup reasons. For instance, Microsoft Office stores a temporary file of the current document every few minutes. These files are typically deleted after you save the document and exit the application. However, if the application crashes, the temporary files might not be deleted, potentially wasting disk space.

By following these steps, you can remove temporary files and potentially resolve the “Sorry, you need to sign out of Teams and sign in again” error. This should allow you to sign in to Teams without any more error messages inhibiting your functionality.

In depth step by step: How to fix “Sorry, you need to sign out of Teams and sign in again” error

Step by step breakdown:

  • First, sign into Outlook.

You will need to sign in with the application version as this process will only work on the application version of Outlook.

  • Go to “file” in the toolbar at the top.

As mentioned above the file option and the application version are the only ways to edit the add-ins as the web version does not directly sync add-in data with your desktop as there is no connected output, unlike the application version.

  • From there visit “options”.

Options are located at the bottom of the menu bar on the left side.

  • Here click on “Add ins”.

Add-ins, like the “Option” feature, are again located at the bottom of the menu on the left side of the display popup.

  • Next to “manage” there will be a dropdown box, here select “Manage COM Add-ins”.
  • Then click “Go…”.
  • Uncheck the box next to “Microsoft Teams Meeting Add-In for Microsoft Office”.
  • Finally, click “OK”.
