Recieving an error message when accessing my delegates in Outlook Client?

Question

Keith Hampshire 71

I'm receiving an error message when trying to open "Delegate Access" in Outlook client. I'm logged in as me on my own Outlook client.

The message reads, "The Delegates page is not available. Cannot access Outlook folder".

I haven't even gotten to the part where I can start delegating access to folders because I keep receiving this message.

Where is your mailbox located? Have you tried sharing a folder via OWA and does it work there?

The mailbox is in Office 365.

Yes, I can share in OWA.

I have many profiles in Outlook client that I use and this is the only one that I can't open the "Delegates Access" settings. Weird....

I'm also getting the same error message on a completely different computer with Outlook client. Outlook client 2019 BTW.

If you have sufficient permissions, try running the following cmdlet to reset the delegate collection:

Remove-MailboxFolderPermission mailbox:\Calendar -ResetDelegateUserCollection
