We're looking at enabling MFA across our organisation, but in pilot group testing we have received feedback from our users that when at home (or other untrusted/unknown network), if the user starts their laptop and three applications try launch at the same time, eg. OneDrive Sync, Skype for Business and Outlook, the user receives 3 seperate SMS/text messages from Microsoft for MFA but appears to cause confusion as to which MFA code relates to which application.
I'd be interested to hear your thoughts or opinions on this and how you'd approach fixing this for users who would encounter this?

I'd strongly recommend using the authenticator app instead with the notification method configured, it's the only method that can give you context as to what the MFA request you're seeing is for.

I believe that you can also force the end users to reset their MFA contact info so it defaults to the app.
Maybe this article will help - https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-mfa-userdevicesettings

Hi Baronne,
I facing a similar issue, have you found any solutions please?
In my case though, when my users log into O365 they receive 3 messages.
All 3 codes contained in each message fail when they attempt to authenticate.
It quite frustrating.

It seems that this hasn't been fixed. Today I got 12 codes for verification most of them (8-9) out of the blue. I'm only using Outlook 2016 and logged online once or twice.

I am piloting MFA and having the exact same experience. Random SMS texts telling me to authenticate on my phone, or multiple SMS alerts when firing up my laptop.
in ADFS 2019, there is this
not sure if the above fixes it
but i can't recommend rolling it out like this. I will have to look at alternative vendors.
