Exchange Control Panel errors on Exchange 2010

I thought of collating some ECP errors I had troubleshot recently.

Error1:

“The user name or password that you entered is not valid. Try entering it again.”

This behavior was caused due to incorrect authentication setting on the ECP VDir (virtual directory)

To resolve this,

Disable “Forms Authentication” on ECP Virtual Directory. Set it to Basic, Windows and Anonymous Authentication

Error2:

After logging into ECP using the admin credentials, and clicking on “Manage your organization” à “Mailboxes”, we get the following error:

‘The Server Method GetList Failed’

To resolve this,

Recreate the ECP virtual Directory by using the cmdlet:

Remove-ECPVirtualDirectory -Identity “Servername\ECP (Default Web Site)” New-ECPVirtualDirectory

Click this link to get more info on how to remove the ECP VDir

Error3:

After logging into ECP using non-admin credentials, we get :

“You don’t have permission to open this page. If you’re a new user or were recently assigned credentials, please wait 15 minutes and try again. If the problem persists, contact your administrator”

Here, if we create a new non-admin account, they could log in just fine. So, this was happening only for old accounts.

Run the cmdlet:

Get-ManagementRoleAssignment –RoleAssignee “username” | FL

We can see “Default Role Assignment Policy” is not added for old accounts

Run this cmdlet:

Set-mailbox “username” –RoleAssignmentPolicy “Default Role Assignment Policy”

Now run,

Get-Mailbox | Set-mailbox – RoleAssignmentPolicy “Default Role Assignment Policy”
