Just recently upgraded Exchange 2013 to CU22, now I am unable to create new mailboxes but I can update / change settings on already created mailboxes within SolidCP.
When creating new mailboxes, the following error is produced - The WinRM client received an HTTP bad request status (400). No settings have been changed on the SolidCP server after the upgrade.
Hello,
Have you rechecked the Powershell virtual directory for windows users?
Thanks,
Trevor
Current PowerShell VDir Settings
Most easy is to check it in ECP,
It needs "Integrated Auth" checked (and nothing else) on the auth tab.
After thats correctly set you could do an iisreset as sometimes it caches the connection/ auth method.
Even with the authentication set to Windows Intergrated, the error still happens. Can you confirm if you have a WinRM HTTPS listener?
