-Outlook 2007, 2010-
Microsoft Outlook Configuration Analyzer is a free tool which will scan your Outlook profile (2007 or 2010) and report on any issues which might be causing you problems.
To use the program, first make sure Outlook is running, then launch the Configuration Analyzer and start a scan.
On our test PC the progress bar estimated a very long scan time (ten minutes or so), but in reality it was all over in a few seconds, so very soon we were browsing the report to see what it had to say.
The first details you’ll see are information on your Outlook configuration: your various profiles, all the addins and third-party modules you’ve installed, the Outlook updates installed on this system, and any settings issues the program thinks might be relevant.
(make sure that Outlook is running before you start an OCAT scan).
