Using the New Outlook for Mac features in business environments
Hi Emilio Horton Torres,
Welcome to the Microsoft Community.
I understand that you are experiencing problems with mobile number verification. Allow me to make some elaborations and suggestions.
Firstly as the error report suggests, this is a server issue. Usually this is a transient issue but I did receive some continuous feedback from users recently.
I understand that you have tried a number of devices and actions.
I would suggest that you could try it on your mobile phone using mobile phone traffic, this will maximise the chance of eliminating some of the disruption.
If that still doesn't work, I'd like to check with you if there is another verifiable way such as an alternate email.
I'll let you know here if there are further developments. Please try and wait a bit.
Best Regards,
