Exchange 2013 Migration - Outlook Prompts For Credentials After Move

[FN-GM]

Hi,

 

When a mailbox is moved from our 2010 to 2013 exchange server when the user opens outlook its prompting the user for credentials. If you delete the mail profile and recreate it all is fine.

 

Any ideas please? @mrbios might know

 

Thanks

Weird, doesn't do it for everyone some users work flawlessly. Any ideas please?

Had the exact same thing but only one user (out of 6 who have been in and use outlook regularly), i ended up doing what you've done and deleting it and adding it again. Haven't looked to see if there's an official fix process for this yet, but it'll be interesting to see if anyone comes up with one here.

It seems to be only people who have a shared inbox. Everyone else seems ok. Hmmm

we had this issue for nearly all our users, changing from userid@emaildomainname to userid@FQDN solved for most, for those who it didn't we just deleted their profile in mail settings and let outlook 2013 recreate it

Oddly enough it just disappeared for us.
