Can't open a shared folder in Outlook on the web in Exchange Server

View products that this article applies to.

Symptoms

Consider the following scenarios:

Scenario 1

  • You have Microsoft Exchange Server 2016 or Exchange Server 2013 coexistent in an Exchange Server 2010 environment.
  • User1 has a mailbox on Exchange Server 2016 or Exchange Server 2013.
  • User2 has a mailbox on Exchange Server 2010.
  • User1 has full access permissions to the mailbox for User2.


Scenario 2

  • You have a hybrid Office 365 environment.
  • User1 has a mailbox in the cloud.
  • User2 has a mailbox on-premises.
  • User1 has full access permissions to the mailbox for User2.
In these scenarios, User1 can't expand the mailbox for User2 after User1 added the mailbox by using the Add shared folder option. Additionally, User1 receives the following error message:
Can't complete your request.

You might not have permission to perform this action.

Note In scenario 2, if User1 has a mailbox on-premises and User2 has a mailbox in the cloud (that is, regardless of which environment hosts which mailbox), User1 can't expand the mailbox for User2.

Cause

The AddSharedFolder request is successful and adds the shared mailbox to the folder list. However, the request to expand the shared mailbox is proxied to the mailbox server for the user. This triggers a "WrongServerVersionException" message and a status of HTTP 500. The HTTP response may include the following:

{"Body":{"ErrorCode":500,"ExceptionName":"WrongServerVersionException","FaultMessage":"The Client Access 
server version doesn't match the Mailbox server version of the resource that was being accessed. To determine 
the correct URL to use to access the resource, use Autodiscover with the address of the resource.",
"IsTransient":false,"StackTrace":"Microsoft.Exchange.Services.Core.Types.WrongServerVersionException: The 
Client Access server version doesn't match the Mailbox server version of the resource that was being accessed. 
To determine the correct URL to use to access the resource, use Autodiscover with the address of the resource.

Workaround

To work around this issue, use the Open another mailbox option in Outlook on the web to open a shared mailbox where you have Full Access permission.

Note: This will generate a redirection link and credentials prompt before you can access the mailbox. For more information, read Mailbox permissions supported in hybrid environments section in this article.
