Exchange online: Conference Room Provisioning changed to AutoAccept

A heads up for admins who plan to provision new resources in Exchange Online: the defaults will change from AutoUpdate to AutoAccept.  This change will occur on November 15, 2018.

What does this mean? It's another 80/20 rule: depends on the type of resources and if you are a new or existing customer.

For existing Office 365 customers:  
  • 80%: Most of our clients configure resources (rooms, equipment) as AutoAccept. If the user wants to book a room on a particular date/time, Exchange will book it if it's free. 
  • 20%: "Managed" rooms.  Those are the ones only specific users can book, or an admin has to approve. Examples are the Executive conference rooms, HR Interview rooms, the Auditorium, etc.  For those rooms, this will be a problem. 
For new Office 365 / Sumatra's Migration customers,
  • NO IMPACT:  For all migration customers, we recommended you set ALL of your rooms to either None or AutoAccept (depending upon the migration tool). You will replace the defaults.
To check:
Get-Mailbox -RecipientTypeDetails @("Equipment","RoomMailbox") -ResultSize unlimited | Get-CalendarProcessing | Format-Table-Property Identity, AutomateProcessing
