Local Move Requests in Exchange Online – Why They’re Not Supported

With all due respect, it is Microsofts own support engineers who often suggest utilizing a New-MoveRequest, so you may want to push out some training to your MSFT engineers. Also - stand by for loads & loads of tickets coming your way for these "one-off" issues - of which I've had SIX since Friday. And we are not a large environment, relatively speaking. In some cases engineers "did a sync" or "diagnostic" (whatever that means - but we corporate EXO admins do not have the capability to do these operations ourselves I'm told) and in others, I was advised to perform a New-MoveRequest - which have been stalling and failing the past week or so. So I've got unhappy customers, and its creating more work for me & my internal support teams.

I will add - I do NOT "Trust the service's automatic load balancing for optimal performance" because too often, issues are one-offs, and secondly - I can't tell you how many times "I" bring medium to wide spread outages to your attention well before your automated load balancing does. Some that result in later MS service advisories, but many that do NOT.
