The account does not have permission to impersonate the requested user.
This error indicates that the specified administrative account does not have permissions to impersonate users and log in to their mailboxes for migration purposes.
When migrating to Office 365, we automatically execute remote PowerShell commands to grant the admin account impersonation rights. However, those PowerShell commands can time out before they complete. In this case, it will be necessary to manually grant permission using remote PowerShell. There is no need to install any additional software in order to do this. Please be patient; the remote PowerShell commands below can take several minutes to complete.
Resolution:
- Make sure the admin account is a global admin.
- Click on the Windows Start button.
- Search for Windows PowerShell (PowerShell should already be installed).
- Start PowerShell under an administrator context (right-click -> run as administrator)
- Run the following PowerShell commands (one at a time):
Set-ExecutionPolicy Unrestricted$LiveCred = Get-Credential$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirectionImport-PSSession $SessionEnable-OrganizationCustomizationNew-ManagementRoleAssignment -Role "ApplicationImpersonation" -User admin@domain.com
Notes:
- Enable-OrganizationCustomization command can take a very long time to run.
- Ignore any error such as "This operation is not available in current service offer."
- Ignore any error such as "The assignment of the management role 'ApplicationImpersonation' [...] won't take effect until user is migrated."
- Make sure to replace "admin@domain.com" in the last PowerShell command above with the global admin account used for migration.

These directions don't make sense for Office 365. It is a web site, I don't have a Windows Start Button in Office 365
These directions make complete sense, as you are using Windows PowerShell to remotely connect to Office 365 services. Followed them completely, and worked w/o issue.
Hello Mike,
There is a bit of propagation that takes place once the permissions are applied. If you have waited 20-30 minutes after applying the permissions and the error is still happening, you would need to create a support ticket here.
Our technicians can investigate the matter further for you.

Followed the information above but get the following notice:
Enable-OrganizationCustomization : The term 'Enable-OrganizationCustomization' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify
that the path is correct and try again.

Hello Tahir,
That error can mean that the admin account you are using to connect to the tenant does not have the proper permissions levels to make the ''Enable-OrganizationCustomization' change. Please make sure the admin you are connecting to the tenant with is a global admin and try again. Another factor that can cause this error would be the credentials being provided in the '$LiveCred = Get-Credential' command had a typo or are incorrect.
If you have any further issues with these commands, please open a support ticket here.

After running the final script, I receive the error -
Multiple user objects match the identity "admin@domain.com". Please specify a unique value. And I did input my username in place of admin@domain.com. Any idea?
I found this thread at Microsoft. https://support.microsoft.com/en-us/help/3001960/there-are-multiple-recipients-matching-the-identity-error-message-when
So, it looks like I need to rename my global admin username to something else.
Yep! That solved the issue.

Hi Support.
I have followed the instructions and all worked fine. Although, its only giving me the option of importing 1 user from 365. And this is the account I have used to setup the endpoint.
Any help with this?
Hello KS,
