I have an Exchange 2010 server that is a 2003 conversion. When we delete users, add users, etc. the additions ro deletions do not show up in the GAL when a user tries to create a new email. It may appear after several weeks, but never in a timely fashion. We have tried to update the GAL manually using the command line, but receive errors. A screenshot of the errors is attached. The domain is a 2003 AD domain with a trust to another domain.
