I realize I'm posting on an article that's 3 years old, but I'm posting here as a last resort as every other support route has turned into a dead end. Worst case, let it serve as a cautionary tale for someone considering going down this path that makes it this far down the comments...
We implemented HMA about 2 years ago for our organization and when it works it works great. It's been our favorite mobile email solution to date. HOWEVER, when it does not work as described it is quite literally impossible to get support for this solution. We've opened a number of cases with Microsoft support and each time, I have to first explain to the member of the Exchange Online team the case has been assigned to what this solution I'm talking about is (I've been repeatedly told no such thing exists). That in itself is fine, but then the case inevitably and without warning gets transferred to some other team - Intune, identity, etc - because the Exchange Online support team does not have the visibility or tools to troubleshoot the issue even when the problem is quite clearly with Exchange.
The_Exchange_Team , on the off chance you see this, how can we get support for this solution? For the past 6 weeks we've been experiencing 30 minute sync delays between our mobile and on-prem environments and have not received so much as a theory as to what's causing the problem. Any suggestions would be greatly appreciated.
