Office phone number format in AzureAD

Copper Contributor

I'm a bit stumped... I'm unable to enter an office phone number in the AzureAD admin control panel.. it is as if the validation rule was hardcoded for US numbers. But I'm in Switzerland, and the user's license usage is set to Switzerland as well. Using MS graph, I can write the number I want (in proper E.164 Format for Switzerland: +41XXYYYZZZZ). It is as if there was some setting that forced the number format to a given country.. but only for the GUI. How can I change that?

If you are talking about this area of Azure AD? Then I just checked it and works perfectly fine. Have a look below.




Thank you


Yup, no issues here either. Just put a space after the country code.
