Outlook is 2007
ActiveSync is Version 4.5.0 (Build 5096)

I am not sure how to locate the current PST files - I scanned my backup PST file and it did find some errors. I guess I could backup Outlook, scan the backup, then restore that backup...

I ran the PIMbackup utility and made a copy of my current files and saved that copy onto my SD card. I used FileExplorer to find the PIM file, tried to delete it but got the following error:

Problem deleting the file "pim"

Any suggestions?

I greatly appreciate your help so far
