 Need to connect to M365 via PowerShell to enable it. It will take some times (1 hour) to be ready. Then you could go back to the GUI to setup.

+Connect M365 via PowerShell
+  * Run Windows PowerShell as Administrator
+  * connect to your M365 with this command, replace navin@contoso.com with your username
+<code>
+PS C:\Windows\system32> Import-Module ExchangeOnlineManagement
+PS C:\Windows\system32> Connect-ExchangeOnline -UserPrincipalName navin@contoso.com
+</code>
+  * Run Enable-OrganizationCustomization
+<code>
+PS C:\Windows\system32> Enable-OrganizationCustomization
+</code>
+The output may display "This operation is not required. Organization is already enabled for customization.". It is okay and just wait an hour for it to be completed.
