When you run SCANPST and it finds errors you need to keep running it until it comes back clean. See if this helps: http://www.officeforlawyers.com/outl...ol.htm#SCANPST

Hi I tried that repeating scanpst.exe method but it did not show my missing folders although tool said "0" errors.I believe there is a synchronizing issue.Hope those missing folders are somewhere in local PC but does not show in outlook due to synchronization issue.What should I do?Thank you.

Hi asiri85,

I too have a similar problem. The same thing happened to a client of mine last week (but actually switching IP address to a different server) - yet of the 10 clients on that domain (all using Outlook 2010) only 1 reported missing folders.

Even more interesting, a client (same company) added Gmail IMAP to their account list, and all of their personal folders disppeared (these were POP3 folders).

Will SCANPST work here?

SCANPST might help. What kind of server was it that you changed from/to? Are your users storing their data in PST files? Are those PST files located on their local hard drives? Do you have them backed up?
