Password popups due to Microsoft changing the office 365 authentication method.

Some users are reporting a persistent password popup in their mail application this morning, this is due to Microsoft changing the Microsoft/Office 365 authentication method and requiring 'modern authentication' by default.

This can also be easily pushed out by 'group policy' if you have a Windows domain.

If you're seeing this in another mail app for example on your phone this will require further investigation and planning.

Alternatively, some authentication methods can be turned back on again but Microsoft has made this change to improve security.
