Hi Greg,
I'm following the instructions above to try the 'Self-Service Re-Enablement'.
When I do the search for Diag: Enable Basic Auth in EXO I get the confirmation of the problem:
Exchange Online POP3 Basic Auth Disabled
Incident # EX402696
Users not configured to use Modern Authentication with the affected protocol may be unable to sign in.
However, when I then click on 'Run Tests' in the diagnostics section underneath, I don't get the option to re-enable any of the protocols - I just get this message instead:
These are the current Basic authentication settings:
The organization configuration is dehydrated. In the Microsoft datacenters, an organization configuration being dehydrated means that it has certain objects consolidated to save space. In this state, configuration cannot be modified. This can be changed by running the Enable-OrganizationCustomization cmdlet.
Note that you are only required to run the Enable-OrganizationCustomization cmdlet once in your Exchange Online organization. If you attempt to run the cmdlet again, you will get an error.
