Hello Exchange world. I have a weird issue that i seriously can't figure out.
Our domain is like thus:
ad.domain - top of the forest
grp.domain - sub tier
We are looking to close down our sub domain trees and only use the ad.domain one. My boss used a migration tool to move the shared mailboxes as a pre step before we move the users. Also he has created users in the ad domain. So they all have a grp.domain login and a ad.domain one. They all all still using the grp ones because the ad ones do not connect to anything.
The issue we are having is after he migrated the shared mailboxes (and went on holidays -_-), I am finding the shared mailboxes seems to randomly lost permissions for like 5-15 minutes. In outlook, it asks for credentials that don't work. However if I log in via owa I get an error message, but if I refresh 1-3 times it seems to regig the account.
Also, we moved one of the users from the old to the new and that mailbox is displaying the following error for 5-15 minutes 1-3 times a day:
X-ClientId: ITBW - 0CMD - T0PA - NEHWX-OWA-Error: SDServerErr;Microsoft.Exchange.Services.Core.Types.MissingEmailAddressForDistinguishedFolderException
X-OWA-Version: 15.0.1347.5
X-FEServer: MX1
X-BEServer: mx1.ad.domain

I'm at the point of manually deleting and recreating each account one by one however I thought about asking if anyone else know what is going on here.
Cheers,
Scylon.
P.S.
this is the error in owa for shared boxes:
X-ClientId: JGCS - GTBW - ZEQH - NAGBWXQW X-OWA-Error: SDServerErr;Microsoft.Exchange.Services.Core.Types.NonExistentMailboxException X-OWA-Version: 15.0.1347.5 X-FEServer: MX1 X-BEServer: mx1.ad.doamin Date: 26/06/2018 23:25:44
