Office 365: Basic Auth being disabled before October 1st

Basic Auth is being disabled in Exchange Online / Office 365 on October 1st and you should switch to OAuth 2.0 for authentication purposes:

Daemons/Services: Password grant (MFA/2FA must be turned off for this account):
Daemons/Services: Client credential flow:
Web apps (requires user interaction):
Standalone devices (requires very little interaction):
Desktop apps (requires user interaction):

However Microsoft is randomly disabling basic auth for some tenants already.

If disabled, you can use a new feature in the Microsoft 365 admin center to request that it should not be disabled yet (until Oct 1st):
