"Specified Message Identity is Invalid" error when you open delivery reports in Outlook

Symptoms

When you open a delivery report (File > Open Delivery Report) to track a sent email message in Microsoft Outlook, you receive one of the following error messages:
The Specified Message Identity is Invalid
The operation couldn't be performed because '{MailboxGUID}' couldn't be found.

Cause

This issue occurs if the delivery report has a corrupted or incorrect URL, or if the URL has an incorrect mailbox GUID. Here's an example of the URL of a delivery report:
https://outlook.office365.com/owa/options/ecp/PersonalSettings/DeliveryReport.aspx?rfr=olk&exsvurl=1&IsOWA=N&MsgID=xxxx&Mbx=%<MailboxGUID>
Note The <MailboxGUID> placeholder represents the mailbox GUID. You can check whether the GUID in the URL matches the GUID in the error message or on the Exchange server.

Resolution

To fix this issue, use one of the following methods.

Method one: Clear the value of the UseRWHlinkNavigation registry entry

  1. Exit all Microsoft Office applications.
  2. Start Registry Editor:
    • In Windows 10, go to Start, enter regedit in the Search box, and then select regedit.exe in the search results.
    • In Windows 7, select Start, enter regedit in the Search programs and files box, and then select regedit.exe in the search results.
    • In Windows 8 and Windows 8.1, move your mouse pointer to the upper-right corner, select Search, type regedit in the search box, and then select regedit.exe in the search results.
  3. Locate and right-click the following registry entry:
    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\x.0\Common\Internet\
    Note The x.0 placeholder represents the version number (Outlook 2010 is 14.0, Outlook 2013 is 15.0, Outlook 2016 is 16.0).
  4. In the Details pane, click and hold (or right-click) UseRWHlinkNavigation, and then select Modify.
  5. In the Value data box, clear the value, and then click OK.
  6. Exit Registry Editor.
  7. Try to open the delivery report again.

Method two: Refresh the value of the UseRWHlinkNavigation registry entry

  1. Open another link in an email message in Outlook.
  2. Check whether the value in the following registry entry is updated to the opened link URL.
    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\x.0\Common\Internet\UseRWHlinkNavigation
    Note When you open a delivery report or any link in Outlook, the value of the following registry entry will be updated to the URL of the delivery report or the link.
  3. If the value is updated to the opened link URL, try to open the delivery report again.
