"I have phantom folders named Edit <0W> X folder (the X increments from 0 to 89 at last glance showing up in a .pst file. I can delete most of them, but 0 and 2 I cannot, and when I close Outlook, a lot of them come back!
Those folders are created by security or anti-spam software, such as Norton or McAfee, that installed an addin in Outlook. Disable the addin to solve the problem of these folders even being created.
The inability to delete those folders indicates the data file is corrupt. Close Outlook then run scanpst and the problem should be solved.
If that doesn't fix the problem, export your data to a new pst file, add it to your profile and remove the corrupt profile.
To disable the addin, go to File, Options, Addins and click the Go button at the bottom of the dialog. Uncheck the addin and close the dialog. More information and screenshots are in the following article:
