Outlook Form Region – Blog


Outlook has certain built in forms that can become corrupted at times. In the most recent case, this issue happened when a user was trying to view their Lync messages in their Conversation History folder within Outlook, and was greeted with the “Outlook Form Region Cannot be Opened” error. Of course, they can double click the email to view the messages, but will not be able to view it in the Email preview.

Follow these simple steps to resolve this issue with the Outlook Forms. This can be done under the user’s profile, and does not need administrative privileges. Proceed with caution when working with the Registry Editor on your PC. Follow the instructions carefully so you do not accidentally remove the wrong key.
1.Close Outlook (This has been tested on Outlook 2013, but should be valid on earlier Outlook versions as well.)

2.Open up the Registry Editor – For Windows 7, Go to Start Menu > Type regedit in the search box. For Windows 8 PCs, go to your Metro Start screen and simply just start typing registry editor and the search will pull it up for you.

3.Navigate to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\FormRegions

4.Just in case, right click FormRegions and select EXPORT, then save this .reg file to your desktop in the event you have to revert back.

5.Delete the entire FormRegions folder from the above registry location

6.Now, Reopen Outlook and try viewing the messages in the Outlook preview to make sure it opens correctly now.

    A minor, but important correction to your post, especially for those of us who don’t spend much time in the registry. The location in step 3 is missing the necessary backslashes:
    Those make all the difference in the world when searching the registry!

    Apparently, some process regenerates the folder and the four keys/values. Not sure whether it is Windows reboot or something else. (FWIW, I’m using Win7 Enterprise and Outlook 2010.) Is there any reason why one shouldn’t just create a .reg file to delete this folder and put it in the Start folder so that it runs at every reboot?

    According to a Microsoft webpage on creating .reg entries, the following .reg file should do the trick (note the dash preceding the key value):

    Windows Registry Editor Version 5.00

      When you delete the registry, it is basically getting rid of the corrupt form data that is in Outlook. If I am not mistaken, Outlook recreates this registry key the next time it is opened up setting it up with a fresh start for the Form Regions. Maybe if it is an ongoing issue and the registry deletion doesn’t resolve it permanently, the next step should be to do an Office repair. I don’t see anything wrong with deleting this on the user’s login, but it would get recreated every time Outlook is opened.
