We have an Exchange 2010 environment on virtual Windows 2008 R2 servers. We have two of them, with Enterprise licenses.
We used to have them split into only a few databases, after which the size of some databases was hitting 1TB. So, we added more storage to our SAN, added more drives to our Exchange and created around 14 databases and began to move mailboxes over to the newly created databases, so that their sizes are smaller. I am one of the people who has moved across to the new database.
I'm using Outlook 2013 64-bit version (used to have 32-bit and still gave the same issues), but every single time I click into my 'Calendar' my Outlook hangs and freezes, then moments later I am prompted to enter username/password. I will cancel it and click into the corner where it says 'Not connected' and then it Reconnects again and shows me my calendar. But from time to time, the application again freezes.
The same thing happens with some of my colleagues. My mailbox size is no more than 4GB.
What could be the cause of these hangs? Is there something we can do to find out what is causing these issues?
Thanks for your help
