We have 2 Exchange server, 1 is an older one that we are trying to migrate to the second.
I am trying to run Exmerge on the 2nd new Exchange server to migrate a user off (PST).
When I run I get the following error:
[09:35:43] Error opening message store (MSEMS). Verify that the Microsoft Exchange Information Store service is running and that you have the correct permissions to log on. (0x8004011d)
I have verified that the IStore services are running, the account I am using has delegated rights to Exchange Full Admin and has a mailbox (not on the new server though...).
One thing I did notice in AD on the new Exchange server, was that when I goto Exchange Advanced of the user's properties, then Mailbox Rights, the "Full Mailbox Access" tab has both the Allow and Deny checked and greyed out?!
