ResourceDelegate does not receive an e-mail requesting confirmation of the booking

When a room is booked through MgGraph, the ResourceDelegate does not receive an e-mail requesting confirmation of the booking.

Nevertheless, a booking appears in the room calendar which is waiting for confirmation, i.e. has not yet been accepted.

These are the settings of Get-CalendarProcessing:

    Hi @deschderman ,

    Welcome to our forum!

    Please check Spam/Junk Folders to ensure that the confirmation email hasn’t accidentally landed in the spam or junk folder of the resource delegate’s email account. Or you can search in your mailbox to check if the confirmation email is arrived.

    If you do not receive this email, in order to further confirm if the issue is related to Graph, it's suggested that you could try to book the room manually to check if the delegate receive the confirmation email.

    If the issue persists, please do the same test on the other room resource to check if there're any difference.
