I have several users that are unable to attach using Outlook over RPC. Two things changed. I moved their mailboxes from a CAS/HT/MB server to a dedicated Mailbox server. I also brought a new CAS/HT/MB server online with the intention to move it to another office after it is fully configured.
I checked the RPC logs and got the following:
2013-04-26T06:05:20.340Z,16351,1,/o=Contoso/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=EC3811ed,,OUTLOOK.EXE,14.0.6131.5002,Cached,,,ncacn_http,,OwnerLogon,-2147221231 (rop::LogonFailed),00:00:00,"Logon: Owner, /o=Contoso/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=EC3811ed in database Houston last mounted on HOUEX01.contoso.com at 4/25/2013 8:58:42 PM, currently Mounted","RopHandler: Logon: [ConnectionFailedTransientException] Cannot open mailbox /o=Contoso/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=EC3811ed. -> [MapiExceptionLogonFailed] MapiExceptionLogonFailed: Unable to make connection to the server. (hr=0x80040111, ec=-2147221231) "
I found that the RPC server specified was the new server I brought online. I changed it to the original CAS/HT/MB Server which is in a pair with the new MB server hosting the mailboxes. The issue persists.
Here is the log of the database hosting the mailboxes.
