Determine Outlook Users

[sadams@bigrocksports.com]

Is there a way to determine Outlook users who are syncing to the Zimbra server? I am thinking there is a string in a log file that I can grep on to see determine these users.

The problem is that every time we upgrade, we email the latest connector to the Outlook users and seem to always forget some. I want to get a list of the users so that I can create a distribution list for emailing the connector in the future.

Thanks,
Shannon
