Hi @Veyselddd
- If the domain is federated, you need to convert the domain to standard by Running below cmdlet on the ADFS Server:
Convert-MsolDomainToStandard -DomainName your-domain.net -SkipUserConversion:$true -PasswordFile C:\pwd.txt
- If AD Connect is synchronizing users with UPN suffix of your-domain.net, disable directory synchronization by using below cmdlet:
Set-MsolDirSyncEnabled -EnableDirSync $false
- Change all UPNs to use your-tenant.onmicrosoft.com domain suffix
Get-MsolUser -All | foreach {Set-MsolUserPrincipalName -ObjectId $_.ObjectId -NewUserPrincipalName ($_.UserPrincipalName.Split(“@”)[0] + “@your-tenant.onmicrosoft.com”)}
- If any distribution groups are using your-domain.net in email address, you need to change that to use your-tenant.onmicrosoft.com domain suffix as well:
Get-DistributionGroup -ResultSize Unlimited | ForEach {Set-DistributionGroup -Identity $_.Name -primarysmtpaddress ($_.primarysmtpaddress.Split(“@”)[0] + “@your-tenant.onmicrosoft.com”)}
- Run below cmdlet to confirm if no user is using your-domain.net in email address:
Get-MsolUser -DomainName labhh.com -all
If any user is still using the custom domain, change/remove that.
- Now you can try transferring the domain again. Alternatively, you can remove the domain by using below cmdlet and add it to another tenant.
Remove-MsolDomain -DomainName your-domain.net -Force
