    Mysteriously this morning it is now all working again as before (as of 9am UK time).

    I can only suggest a MS glitch yesterday which is now resolved.

    Thanks for all and any assistance from those on this thread and any others who noticed and were in a position to get it fixed. 🙂

    Kindest,

I have been trying now for 10 consecutive days to get into my work email using the text verification and the messages are not being sent. MAY 2021. I have no other option set up, is there any way to circumnavigate the text or add another option? Everything returns to the same mobile text verification option .

Hi,
You don't say where in the world you are, but I only mention as MS have different service components around the globe and a fault in the UK is unlikely to affect elsewhere...

I'd try using an unauthenticated browser (maybe Incognito mode) and go to https://aka.ms/MFASetup as this goes direct to the setup portal for your MFA. I'm assuming that might let you log in okay and allow you to change your MFA details.

If you have setup more than one method when you first configured MFA then you should be able to select alternatives on the web module that requests a text response (i.e. a second mobile number or an email to alternative ISP etc.).

If you didn't set up a second MFA Auth method, why not?

Assuming you have only setup one MFA Auth (SMS) then in the event you made a typo in the number then you'll never get the text... You may need to contact MS Support for that as you may have no way of getting in... get them to clear your MFA, then you can set it up again (two of them!).

HTH?

    Thanks Andy! I'm in the UK and yes, tried all the options you've mentioned, everything returns to the verification texts, I'm waiting for MS support to get back to me. Helpful to know I'm not being stupid though,
