"Mailbox Import Export" role issue

[MiSum83]

Hello,

I'll be doing emails migration soon and would need to import PST files. Would like to use the Import tool available in MS Purview.... However, to be able to use Import feature, I need to add "Mailbox Import Export" role in Exchange Online.... I was trying to add that role but getting the error below... I've been trying to do it for 2 days already and still no luck.... The error doesn't give me any idea of what could be wrong...

I have a "global admin" group in "Assigned" tab and I'm logged as an admin that is included in that group.

Any idea what I'm doing wrong here?

Seems you are not the 1st or 2nd user hit the problem, may raise a ticket to Microsoft to check from the back:

"We couldn't save your changes. Please try again." error and July 2022 - Microsoft Community

Try adding the role via PowerShell:

New-ManagementRoleAssignment -Role "Mailbox Import Export" -SecurityGroup "Organization Management"

Or, you can directly assign it to the user(s) in question:

New-ManagementRoleAssignment -Role "Mailbox Import Export" -user admin1

the powershell worked.

1stly - it reported an error mentioning that I'm not allowed to make changes in roles.... So I have removed the global admin account I was using, created new one again... After connecting via powershell, the command ran with no issues and the role has been assigned.

Thanks!
