Now close any Office apps.and open.I usually pick Word first.I have them log out of Word (if 365 sourced).log in.username, password.approve MFA. On their computer, log out of, log in.test.show them the ropes. I have the user open the app, skip the backup stuff, go to add account, Work/School out of the 3 choices, allow app to access camera.hold camera up, I click next.have them grab the QR code, send the test.they approve.and then fill in the cell phone number in the next screen as the alternate method for the old fashioned text code to phone approach. I prefer the 'Approve/Deny' method via the Authenticator app.so I select the radio button and download menu choices for Auth app and send request to phone. I remote into their computer.I then open on their computers then the expected 'Additional information is required' dialog box kicks in. Once I'm doing the phone/remote session with them, I have their 365 tenant open on my computer, I enable MFA on their account. Once they have that installed, you can then schedule your remote session. Saves you time on the phone, there's always a few users that have an iphone and don't know their Apple ID which is required to install from the iTunes store.so you don't want to deal with that time waster while on the phone. Send out an email explaining how to do so. I have clients download the Microsoft Authenticator app.ahead of time. I'm doing a migration of a client this week and each day getting several users setup on it.for Teams, OneDrive, etc.
