Outlook not displaying images
Jan8
If you are having trouble seeing embed images in your outlook emails here could be the issue. Outlook uses a temporary folder to cache images and files that are sent with emails. Sometimes this folder gets corrapted and the only way to fix it is to clean out the directory with the cached items.
To find out where the folder is on your system go to start > run > type regedit. Be very careful here this is the operating systems central nervous system. DO NOT MAKE CHANGES TO THIS! in the regedit program browse down to this path HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security. When you get to security look for the value OutlookSecureTempFolder this will contain the path to the folder you will need to clean out. Find that folder and delete everything in it. Then restart outlook. If you had a lot of files in this folder you should notice outlook running faster. I have only tested this with outlook 2003 and windows xp professional.

I have a user running Outlook 2002 that had the same problem. Your solution did work on that version as well. The only difference was the path. Being an earlier version it is: ~ \Office\10.0\Outlook\Security vs.~\Office\11.0\Outlook\Security. After deleting the 1000 plus items in the folder images would display in emails, and Outlook was running faster.
Thank you for taking the time to post your knowledge.

This worked for one of my users as well – WinXP Pro/Outlook 2003. She had over 2500 items in the temp folder!
