[dba-Tech] Outlook 2010 hanging up

I've installed Outlook 2010 so I can write about it, but I'm not using it. Today, I forwarded some messages while working up an example and Outlook hung up for several minutes. I tried a couple of times and had to cancel. Most of the tasks are marked completed, but there's one I'm not familiar with -- says it's synchronizing subscribed folders -- that's what holding things up. I get the following info, which means nothing to me: 

The TCP/IP connection was unexpectedly terminated by the server.
 Protocol: IMAP
 Server: imap.gmail.com
 Port: 993

Anyone familiar with this particular "task?"
