Post-Migration - Outlook Access Denied

Body

You Don't Have Access to This

In this Article:

Description of Issue

Upon launching a Windows desktop version of New Outlook, a window may pop up with a message telling users:

  • You don't have access to this.
  • Your sign-in was successful but you don't have permission to access this resource.

After closing that window, a new window pops up with the options to continue or choose another account. However, picking either option causes a login loop of entering the correct credentials but never successfully logging into Outlook. This issue is due to a cached credentialing issue that can be resolved with a few short tricks. 

Examples of some common screens seen so far:

Text on screen: You don't have access to this. Your sign-in was successful but you don't have permission to access this resource. Text on image: You need to sign in with campus email listed. Options to continue or choose another account.

Warning 

Please note that this solution has worked for most devices, but not all devices (notably Surface Pro). We are actively looking for solutions on the various non-University managed machines. As an alternative, you may wish to use Outlook Classic, which does not seem to be having these issues.
