+==== Enable-OrganizationCustomization ====
+<note important>The command you tried to run isn't currently allowed in your organization. To run this command, you first need to run the command: Enable-OrganizationCustomization.</note>
+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.
+https://docs.microsoft.com/en-us/powershell/exchange/connect-to-exchange-online-powershell?view=exchange-ps
+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.
