These are the possible solutions to this issue. Listed in order of most common solution to rarest solution.
It is possible you somehow disabled SpamBully.
Have a look in outlook. Help menu>About Microsoft Outlook>Disabled Items – make sure SpamBully is not disabled.
Also try going to Windows Start Menu>SpamBully for Outlook Menu>Enable Spam Bully.
Then right click on the outlook top menu, make sure SpamBully is listed and checked there.
Then make sure you have installed all of the latest service packs for Office. http://office.microsoft.com/ProductUpdates/default.aspx
Next do a complete uninstall of SpamBully for Outlook and make sure you reinstall the latest version.
1. Close Outlook or Outlook Express. Go to your windows control panel > select add or remove programs. Find spambully 4 in the list. Make sure Spambully For Outlook and Spambully Training Data files are both checked and click uninstall.
2. Shutdown and restart.
3. Then download the latest version from http://www.spambully.com/download.php and install SpamBully.
Make sure Outlook is closed while you do this.
If you still have issues, it may be that a file in Outlook has become corrupted.
Do a search for the file outcmd.dat. When you find this file with Outlook CLOSED, rename this file to something else. Then when you reopen Outlook it should automatically receate this file.
To prevent possible future corruption of this file, it is best not to move items around on the outlook toolbar and also don't hit those little down arrows which appear at the end of some toolbar lines.
