Cannot cancel meeting RRS feed

  • Question

  • I have a client who have moved from Office 365 to Exchange 2019 on-premise.

    Mailboxes have been backed up with Veeam from Office 365 and restored to the mailboxes on-premise with Veeam.
    At least one user is now complaining about issues with cancelling meetings.
    When trying user is getting an error message "You are not allowed to send the message on behalf of the specified user."

    It is only for meetings created when they were in Office 365.

    I suspect it is a permission issue, but I cannot find a command that shows me permissioins on items in a mailabox or a command that pushes permissions from parent folder to all folders and items in the mailbox.

  • I have clicked around in the program but I cannot see how I can change permissions on items.
