Hi,

Please provide more information about your issue. If all users can't connect to this server, please do the following steps to narrow down the issue:

1. Make sure all services are started and running on your Exchange 2010.

2. Create a new profile for the problematic users who are hosted on this Exchange 2010.

3. Is there any error for the failed connection in Outlook
