Hi,
Currently the basis auth was enabled, I run the diagnostics hope to opt out the basic auth, but i got below message,
{
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 https://docs.microsoft.com/powershell/module/exchange/enable-organizationcustomization?view=exchange-ps 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. }
need https://docs.microsoft.com/powershell/module/exchange/enable-organizationcustomization?view=exchange-ps first?
Regards,
Tommy
