A user is repeatedly prompted for credentials during sign-in to Office 365

Hi I am having an issue with a user getting access to their mail on 365. When the user tries to access their account through Internet explorer it asks to authenticate over and over. Just to go through our setup we have exchange 2013 hybrid setup with adfs. I have just started to migrate users up to 365 and out of 30 only one user was having issues getting access?

Whenever I've came across this it's been down to an incorrect password being supplied. Had it changed recently and the DirSync had yet to run maybe? Be interesting to try accessing outside of your network and see if you have the same authentication issue.

I've reset the students password. Forced a sync and tried to log on externally which works.

Hi,

 

If possible, can you drop me a PM with the UserPrincipalName of the affected account, or better still if you can get a Decrypted Fiddler Trace and drop me that to me also I should be able to see what is going on here.

 

Thanks,

James.
