We have a problem that engineers from the service desk cannot create or enable mailboxes using ECP.
The following roles have already been assigned to the engineers. Everything works except the "User Mailbox"
They get the following error "500 unexpected error". Can anyone help with further troubleshooting?
Active Directory Permissions
Mail Recipient Creation
Done the following troubleshooting steps:
- Pointed to a specific server http://<servername>/ecp
- Connected exchange remotely using the engineers admin credentials . enable-mailbox command is working and they can enable mailbox.
