Exchange Error after migration to Office 365

Been seeing this error in our Exchange Server Application Log since we completed the migration for this user. After some searching I still have nothing. Has anyone seen this error or have an idea of how to fix it. From what I can tell, the user is unaffected.

Microsoft Exchange Information Store service encountered a corrupt AD object with ID (fa2f2782-2b6d-42d5-9af6-48713ba92d87). Error text is (Mailbox Database attribute is null mailbox location type Primary for recipient fa2f2782-2b6d-42d5-9af6-48713ba92d87

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi,

Probably something went wrong while converting from mailbox to a mail enabled user for any reason (permissions, illegal character and so in)
Solution is to convert manually but there are Some cave-eats.

In the link below you can find a script that deals with them.
