- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Importing PST files into Microsoft 365 and attempting to assign necessary migration role groups.
- Observed behavior
- A role group creation error blocks the process, requiring the execution of the Enable-OrganizationCustomization cmdlet to proceed.
Ensure you have Exchange Administrator or Global Administrator privileges in Microsoft 365, and verify that the Exchange Online Management module is accessible on your system.
Run Enable-OrganizationCustomization via Exchange Online PowerShell
Use this method to authenticate your tenant through PowerShell and activate the customization features required for PST import role assignments.
By default, Microsoft 365 tenants are created with a dehydrated state to save space. Before you can make changes to role groups for PST imports, you must enable organization customization using PowerShell.
Launch PowerShell on your computer as an Administrator.
Install the necessary module by running 'Install-Module -Name ExchangeOnlineManagement'. If it is already installed, load it with 'Import-Module ExchangeOnlineManagement'.
Execute 'Connect-ExchangeOnline -UserPrincipalName your_email@domain.com' to sign in with Multi-Factor Authentication (MFA). If MFA is disabled, use the 'Get-Credential' command to authenticate.
Type 'Enable-OrganizationCustomization' and press Enter to activate the necessary settings for your Microsoft 365 tenant.
Once the command executes successfully, return to the Microsoft 365 compliance portal and retry your PST import or role group assignment.

Frequently Asked Questions
Why do I get an error saying Enable-OrganizationCustomization is already enabled?
This indicates that your Microsoft 365 tenant has already been hydrated or customized. If your PST import still fails, the issue is likely due to propagation delays or insufficient administrator permissions.
Can I run Enable-OrganizationCustomization on a Mac?
Yes, Mac users can manage Exchange Online by installing PowerShell Core for macOS and then installing the ExchangeOnlineManagement module via the terminal.
Do I need to run this command every time I perform a PST import?
No, the Enable-OrganizationCustomization cmdlet only needs to be executed once per Microsoft 365 tenant. Once enabled, the customization state remains permanently active.
What roles do I need to run this cmdlet?
You must be assigned the Organization Management role group in Exchange Online, which is typically granted to Global Administrators by default.
