SBS 2011 server having some issues when we open calendar from Outlook 2010

On a users machine when outlook is opened the mailbox opens in just a few seconds like it should. But when I go to open the calendar, this process can take several minutes to complete. It will sit and hang like it is busy. I ran outlook.exe /rpcdiag and it showed me the calendar request was trying to open "mail.companydomain.com" versus using 2k11sbs.companydomain.com (internal name). Other requests all use the 2k11sbs.companydomain.com which is the internal server name vs the external DNS name. I can't seem to find out where the calendar is trying to open the external DNS name from.

The issue is resolved. This was a problem with iCloud integrating into Outlook 2010 after a recent update.
Removing / unchecking iCloud from the addins page (Comaddins) resolved the problem.

I unchecked the cached exchange mode, but still no go

I don't expect any points, just glad I could resolve the issue. I have seen that iCloud application updates for windows machines have caused some issues in the recent past.

Thought I would try this.
