“The custom form cannot be opened. Outlook will use an Outlook form instead. The form required to view this message cannot be displayed. Contact your administrator.”

We’ve been messing with custom forms in Microsoft Outlook and Microsoft Exchange lately. I had one user who tried openning a custom form in Microsoft Outlook 2007 and they received the error message below

CustomFormError

The fix for this was actually very simple. Below are the steps that solved our issue.

Open Outlook 2007
Click Tools at the top
Scroll down and click Options
Click Other tab
Click Advanced Options button
Click Custom Forms button
Click Manage Forms button
Cick Clear Cache button
Close out of everything except Outlook and you should be good to go!

Thanks. This seemed to help with Outlook 2010 as well.
