Exchange mailbox permissions & processing

When setting up your MTR device, it is important to remember the exchange calendar!

All of the systems behaviour is directly controller by the exchange mailbox, if the system isn't showing scheduling information or "join" button, please check our the below.

ANY CHANGES TO THE EXCHANGE BOX, will take 24-48 hours to fully replicate, to behaviour maybe intermittent!

ALWAYS run the commands in powershell, not all commands are available in the Exchange admin portal


In addition to the MS requirements you may also need to do some additional Powershell work on the mailboxes to allow for external invites (not in the exchange admin portal).

The following commands are important:-

-DeleteComments $false -DeleteSubject $false

Set-CalendarProcessing -Identity yourResourceMailbox@yourdomain.com -ProcessExternalMeetingMessages $true

here is a string that should help

Set-CalendarProcessing -Identity <insertresourcename> -deletecomments $false -deletesubject $false -ProcessExternalMeetingMessages $true

A full command list for mailbox processing is here:- https://docs.microsoft.com/en-us/powershell/module/exchange/set-calendarprocessing?view=exchange-ps
