This is an issue with Meeting Responses and updates. This has only happened since the migration. I have been testing with TO’s and colleagues to replicate the issue. The problem still occurs even when “My delegates Only” is set under delegate permissions. Example Scenario: My colleague was setup as a delegate with editor permissions on my calendar. “My delegates Only” was also set under delegate permissions. He created a meeting through resource central under my mailbox. The results of the test show: See attached two e-mails. 1) New Reservation of…: I received this e-mail 2) FW: Test Meeting 3…: My colleague received this e-mail I also received Updates to Meeting. So to summarise, the delegate only gets acceptance messages and not the changes or updates. The organiser who wishes for the updates to go to the delegate is receiving the updates
