Exchange Online - Standard Authentication will be permanently disabled starting 01. October

Hello everyone!

All admins who still use the Standard-Authentication Method in Exchange Online (M365) in production are strongly advised to change this as soon as possible because this feature will be deactivated permanently at the end of the year. The deactivation will be carried out in stages from 01 October 2022 in all tenants. From this date on, you should expect the permanent deactivation at any time.
There will be no exceptions for tenants this time.
