Howdy! I am getting the following error when saving an extension when I am editing anything in the extension. An exception occurred EditExtension Error: Server execution failed. I have added/remove BLF's or change the email address. Same issue. Once I press ok to clear the message the dialog closes, and my settings appear to be changed. When open the extension again, the settings appear to take effect. 12.0.37098.738 SP.6.1 I have also seen a similar error: An exception occurened MailForm Error: server execution failed. any ideas? I have seen this for a while. I did a uninstall/re-install and restore of the data, and the problem was still there. Thanks!
