What is disabled in Outlook 2003 running in Safe Mode?


One of my users complained today that emails in his Outlook 2003 were taking time to open up. When i had a look myself, i noticed that only emails with attachments were taking time to open (15-20 seconds). Emails WITHOUT attachments were fine.
I restarted outlook in safe mode, and this seemed to resolve the problem.

I then checked his add-ins and COM add-ins and he didn't have any 3rd party addins installed. Just the same default add-ins that everyone else has. (including Symantec antivirus add in), and he doesn't have any COM add-ins.

But as soon as i run outlook normally again, the problem returns. Running Outlook in safe mode seems to be resolving the issue, but i don't know what exactly it's doing to solve the problem. Is there any way of finding out what exactly is being disabled and turned off? I tried going to Help>About Microsoft Outlook>Disabled Items, but it said that there were no items to display. I even renamed the outcmd.dat file, but that didn't resolve the issue either.

Best Regards,

It's most probably the AV. Disable Symantec AV for Outlook as a test and retry. You might also have some infection on the machine, run an AV scan.
Greetings connelvalentine !

Outlook Safe Mode disables the addins.  Disable all the addins and test.

If no joy, check if Outlook cache is full. Delete the files in OLKxx folder (where xx stands for some random numbers).  OLK is difficult to find. Follow the procedure in this webpage"

connelvalentine, any update?
