I have a strange issue. I recently setup a not-for-profit organization with Office 365. They only have four employees with each having brand new laptops running Windows 8.1 Pro 64bit. Three of the four are running retail versions of Office 2013 with the other running Office 2013 installed from Office 365. All of them are having the issue of Outlook constantly asking for a password every time it's launched. I've checked the credential manager, autodiscovery tests that all pass, firewalls, reinstalled office, and created new profifles, but not having any luck. They share a network with another office that has identical laptops with Office 2013 that doesn't have this issue. The only difference is they are on a different 365 plan and do not use Box.com for cloud storage.
I've brought my personal laptop in that has the same Office 2013 and created a profile of theirs and I can't get it to ask for a password.
I've read somewhere that it might be related to an improper global catalog server registration, but I'm not sure with them using 365.
Anyone have experience with this that might be able to shed some light on it?
