WINXP BUILDIN OUTLOOK EXPRESS 5  COMPRESS COUNTER RESET TO ZERO EACH TIME

Hi Stanley you will need to create a reg file first. In regedit, can you click on the link you provided, then File > Export say to your desktop, and name the file CompressFix.
Right-click on the file, select edit, and strip out everything except for the key name and the CompactCheckCount, so when finish editing the file would look like this or similar:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Identities\{identity}\Software\Microsoft\Outlook Express\5.0]
"CompactCheckCount"=dword:00000001

Select all Open in new window

Then just double-click on the file to reset each time
You should think about moving your mail to Gmail soon though, sounds like your Outlook is ready to crash.
Let me know how it goes
