Learn how to exclude attachments and notes from a resource calendar in Microsoft Exchange
Many organizations have the policy of ensuring that no attachments and notes are related to a resource calendar. Here is how to ensure this:
Connect to Microsoft Online using PowerShell and execute the following, where <Identity> is the email of the resource calendar:
Set-CalendarProcessing -Identity "<Identity>" -DeleteAttachments $true -DeleteComments $true
Note that attachments and notes of existing meetings in the resource calendar will not be deleted unless the meetings are updated.
