Two-factor authentication

Two-factor authentication is login with more than just a password. From the 29. of June, in addition to your password, you need to confirm your identity either by using a mobile app (“Microsoft Authenticator”) or by providing a code sent to you by SMS when signing on to Office 365. Configuration of two-factor authentication for Office 365 is documented here. Two-factor authentication in Office 365 can be set up on and is separated from two-factor authentication on the internal NMBU services, which are set up at

Old authentication protocols disabled

When activating two-factor authentication in Office 365 we are disabling some old authentication protocols that do not support requiring two-factor. These are protocols like POP and IMAP. If you are experiencing email issues after the 29 of June, you might have installed an application using one of these old protocols. We recommend using the official applications from Microsoft, as they are fully supported.

Devices with Office 365

Devices (PCs, tablets and mobile phones) and applications set up with Office 365 services must be logged out and logged in.


If you have previously shared a OneDrive document, the old sharing link will no longer work. You will therefore need to reshare the document if the recipient is to be able to read the document.


Old Path:
New Path: 

OneDrive – Sync

The sync app will automatically switch to sync with the new OneDrive path after a UPN change. Users may see an error in the OneDrive sync app that “One or more libraries could not be synced.” If they click for more information, they will see “You do not have permission to sync this library.” Those who see this error should restart the sync app. The error will disappear by itself after a while.

Recent files lists

“After a UPN change, users will need to browse to re-open active OneDrive files in their new location. Any links to the files (including browser favorites, desktop shortcuts, and “Recent” lists in Office apps and Windows) will no longer work”.
