Desktop Suite in Microsoft Office365 logs out of email frequently

Question

My boss's Microsoft Office365 subscription for the desktop suite is logging out every few hours on both of their devices (running Windows 10), requiring them to log in again with a code sent to their email. This is happening across all products in the suite and is causing significant efficiency issues. Can anyone suggest a solution?

Answer 1

It seems that the issue is related to the user being signed out of their Microsoft 365 account frequently, which is causing efficiency issues. One possible solution is to delete the SignedOutADUser registry key, as described in the "Workaround" section of the first context provided. However, it is important to follow the steps carefully and back up the registry before making any changes. Another possible solution is to follow the steps outlined in the "Solution" section of the second context provided, which involves signing out and then signing back in to the Microsoft 365 account. It is also recommended to close all web browsers after signing out of any Microsoft 365 web application to prevent session cookies from inadvertently being re-used, as explained in the "More Information" section of the third context provided.
