Hello all,
Looking for some clarification on an issue we are seeing.
On-prem Exchange 2013
Office 365 E3
Hybrid connector
AADC synching accounts to O365
On-prem ADFS server
In local AD, their internal domain is set to "<orgname>.local"; before moving them to the cloud, we change their UPN to "<orgname.ca>" so that it matches the domain configured in O365.
According to what I have read...
(for example, here: https://blogs.technet.microsoft.com/exchange/2015/03/23/exchange-activesync-on-boarding-to-office-36... )
...when users get moved from on-prem to O365, their mobile device ActiveSync profile should get automatically updated and they should have nothing to reconfigure on their mobile devices.
However, this doesn't seem to be working; the engineer working on this says that it's because of ADFS; he says:
"it looks like all Active Sync historical profiles must be recreated to point directly to Cloud following the Cloud mailbox move event. Currently, I am not aware of any main stream way to get the existing On Prem Active Sync profile to continue working after a mailbox move to a Cloud ADFS front ended configuration"
True or not? If not, then any ideas what the issue could be?
Thanks!
Jacques
