We've used SpamBayes for several months on 2 Windows XP (with Outlook XP) machines with no problems - it's a terrific product and we plan to deploy it for many of our 100+ users throughout the college. Last week we installed it on a Windows 2K (with Outlook XP) machine, and it seemed to be working fine. But when the user logged off and logged back in (he had Outlook in his startup folder so it loaded automatically on login), Outlook froze and an error message popped up saying that SpamBayes had caused a fatal error. The error asked if the user wanted to deactivate SpamBayes so Outlook could load, and he selected yes. Outlook loaded fine, but the SpamBayes buttons were gone from the toolbar. The user then called me for help. A description of what I tried is listed below. In each case, "FAILED" means the Object Libraries didn't load upon the first opening of Outlook after installing SpamBayes, and the SpamBayes buttons didn't show up on the Outlook toolbar. 1. Followed your suggestions in troubleshooting.html for resetting Outlook's toolbars and checking the logs. The logs contained no errors, and resetting the toolbars didn't bring the SpamBayes buttons back; Result: FAILED 2. Un-installed SpamBayes from the control panel; rebooted; re-installed SpamBayes; Opened Outlook; Result: FAILED 3. Un-installed SpamBayes and Outlook XP from the control panel; rebooted; re-installed Outlook XP (+ updates); re-installed SpamBayes; Opened Outlook; Result: FAILED 4. Un-installed SpamBayes and Outlook XP from the control panel; deleted all SpamBayes entries in the registry; rebooted; re-installed Outlook XP (+ updates); re-installed SpamBayes; Opened Outlook; Result: FAILED 5. Un-installed SpamBayes and Office XP from the control panel; deleted all SpamBayes entries in the registry; rebooted; re-installed Office XP (+ updates); re-installed SpamBayes; Opened Outlook; Result: FAILED 6. Un-installed SpamBayes and Office XP from the control panel; deleted all SpamBayes entries in the registry; Re-installed Windows 2000 Service Pack 4; rebooted; re-installed Office XP (+ updates); re-installed SpamBayes; Opened Outlook; Result: FAILED Each time SpamBayes was re-installed, the SpamBayes folder was put in C:/Program Files, and SpamBayes showed up in the Control Panel. But for some reason it will not load up with Outlook no matter what we do. Any help would be greatly appreciated. Thanks, Brandon M.
