Outlook Cached Address showing as SID

A client of ours just moved to a new domain, as their PDC died.  They use a hosted exchange service.

When migrated to the new domain, one of the users has SID's showing up instead of an email address when they start composing an email address.  Anyone seen this before?

The SID's would be associated with the old dead domain, so you would need to delete them from the NK2 file in Outlook and have them recreated next time they compose an email.

I have opened up their new Outlook profile, started entering the email address, deleted the cached entry, and then typed the entire email address and sent a message successfully.  Tried to address another message, and the same SID issue is showing up again.
You can open the file with this utility and remove all bad listings.  


Have you tried to delete/recreate the Outlook profile?
