Description
The other day when I try to update the Offline Address Book in my Exchange Server, I get an error like this:
Exchange System Manager Error. The information store could not be opened.
The logon to the Microsoft Exchange server computer failed.
MAPI 1.0 ID no: 80040111-0286-00000000
ID no: C1050000 Exchange System Manager
Resolution
Make sure that the DNS and Active Directory are function correctly in your domain. Run DCdiag and Netdiag to make sure everything is ok.
Restart the Domain Controller and then restart the Exchange Server.
