I'm trying to set a delegate for a mailbox via powershell in Exchange Online (Office 365), but the delegated user does not receive the "Meeting Accepted" messages. I've tested it with my account, and I don't get the meeting accept messages.
I've read that the ResourceDelegates parameter for Get-CalendarProcessing is only for resource mailboxes, yet when I set the delegate as Editor on the Calendar and give them GrantSendonBehalfTo, it updates the ResourceDelegates to that user.
All of that aside, the fact that I got this to work before but I can't now is driving me absolutely insane. I know that you can set the delegate within Outlook, and then set it to forward the meeting messages to the delegate, but I can't seem to get it to work via powershell. Help?
