Hi,
I'm having problems with Busy search from GroupWise to Exchange. Everything else works perfectly: mail flow, directory sync, free/busy lookups from Outlook to Groupwise.
However, when GroupWise user tries to perform a busy search he receives nothing. In the Gateway log I'm seeing the following error: Could not get TimeZone of the Exchange User
