User is unable to remove old delegates that no longer exist RRS feed

  • Question

  • I have a user that has 2 names in his delegates list that are terminated users no longer in the address book.  When he tries to remove these users and save delegate changes in Outlook, he gets the error "The modified permissions cannot be saved".  He is able to add and remove other users without issue.  User is on Outlook 2016 / Windows 10 v1803.

    How can we get these non-existent users out of his delegates list?

  • What kind of delegates are those? If they only have access to the calendar, you can try removing them via the Remove-MailboxFolderPermissions cmdlet, which now supports delegate scenarios. Otherwise, you will have to remove them via EWS, here's a good module to get you started: http://www.flobee.net/powershell-module-for-managing-exchange-2010-mailbox-delegates/

  • Hi Rasmussen,

    Agree with Vasil.

    Except above suggestion, you can also try removing calendar permission via OWA and check if any helps:

    Login OWA --> Calendar --> Right Click "Calendar" folder --> Permission --> Remove the delegate user's permission --> Save --> reopen outlook to check if delegates have been deleted 

    like below:
