Users is unable to access OWA options (ECP) in Exchange 2010 and 2013

This is not an especially new issue but there is not much information about it so here goes anyway.

The issue

Some users, but not all, of a customer of mine reported that they could not save their signatures in OWA. After some investigation I found that the users that could save their signature had the an Role Assignment Policy set, “Default Role Assignment Policy”. This was the only policy in use and all users should have that policy.

When I did a quick check online, some had reported that the following event with event ID 4 and the error message "The user "username" isn’t assigned to any management roles."  where logged in the Application Log on the CAS servers. However, my customer had no such events in the Application Logs on their CAS servers.

The users that could not save their signature had an empty Role Assignment Policy attribute set. Exchange needs to have the RoleAssignmentPolicy property (msExchRBACPolicyLink  attribute) to be able to determine which settings the users has the rights to change in ECP. This is based on RBAC and if you want to read up on Role Assignment Policies have a look here.

Lets have a look at this in more detail. I have got two users, Test User1 with no policy set. And Test User2 with the “Default Role Assignment Policy” set. We will start with the first user…


A broken Mailbox

Test User1 (no policy set)
Run the following command to view the RoleAssignmentPolicy property.

Get-Mailbox <identity> | Name,RoleAssignmentPolicy



As you can see, the RoleAssignmentPolicy property is empty. In ADSI Edit the attribute you should look for is called msExchRBACPolicyLink as shown below.


As you probably have guessed already, the attribute is empty for Test User1. If I go to OWA and try to change some of the options I receive the following error message “Sorry! Access Denied. 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.”.

In both Exchange 2010 and 2013 the message looks like this.



A working mailbox

Test User2 (“Default Role Assignment Policy” set)

Again, run the following command to view the RoleAssignmentPolicy property:

Get-Mailbox <identity> | Name,RoleAssignmentPolicy



Much better as you can se, when we use ADSI Edit the msExchRBACPolicyLink contains the Distinguished Name of the “Default Role Assignment Policy”.


For Test User2 it works fine to change the settings in ECP.


Why did it happen?

I did some more investigating and found that the reason that this issue occurred for some users was that my customer create some mailboxes using AD Toolkit. When AD Toolkit creates the mailboxes the msExchRBACPolicyLink attribute is not set.

This can be achieved in AD Toolkit as well by adding an attribute when creating the mailboxes and specifying the msExchRBACPolicyLink attribute with a correct Role Assignment Policy.



Well the easiest way to solve the issues is to add a Role Assignment Policy for the affected mailboxes. To find all users with an empty msExchRBACPolicyLink attribute you can run the following command.

Get-Mailbox -ResultSize Unlimited | Where { $_.RoleAssignmentPolicy -like $null}



To add a Role Assignment Policy for all the listed users run the following command:

Get-Mailbox -ResultSize Unlimited | Where { $_.RoleAssignmentPolicy -like $null} | Set-Mailbox –RoleAssignmentPolicy “Default Role Assignment Policy”



And that should be it, all users should now be able to change their settings in ECP.

Access rights error when moving mailboxes from Exchange Server 2003 to Exchange Server 2010

When I did the mailbox migrations from Exchange Server 2003 to Exchange Server 2010 yesterday, I received the following error for a couple of mailboxes:

Active Directory operation failed on <DomainControllerName>. This error is not retriable. Additional information: Insufficient access rights to perform the operation.
Active directory response: 00002098: SecErr: DSID-03150E8A, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

The user has insufficient access rights.

Exchange Management Shell command attempted:
’<PathtoOrganizationalUnit>’ | New-MoveRequest -TargetDatabase ‘Mailbox Database 147171981′ -BadItemLimit ‘-1′

In my case, this was caused by inheritable permissions for the user object. To check this setting do the following:

  1. On a domain controller, Open Active Directory Users and Computers.
  2. Make sure that you have advanced features activated. Choose view and then Advanced Features.
  3. Find the user that matches the mailbox you where trying to move.
  4. Open properties for the user and navigate to the Security tab.
  5. Click on Advanced and activate the checkbox Include inheritable permissions from this object’s parent”, then click Ok twice.

And that should do it, you can try to move the mailbox again and it should work. Thanks for reading and do not hesitate to let me know if you run in to any problems!
