MS Office Forum / Outlook / Programming Add-Ins / April 2004Help! Addin keeps getting disabled in Outlook 2003
I have an addin that works as expected in Outlook 2000. One of the users recently upgraded to Outlook 2003 and has the following problem. Each time he uses the addin he has to first go to the Help menu, then to About Microsoft Outlook and click on Disabled Items to revive the program. Then he has to close Outlook and reopen it. Then he gets the addin and it works fine. But then the next time he starts the computer, he gets an error message durring start up that says Microsoft Outlook has encountered a fatal flaw with the addin and will need to disable it. This puts the program back into the Disabled Items location until he retreives it again. There is NO error message caused by the addin at any point. Please Help. Any ideas will be greatly appreciated. Thanks Sanjay These are symptoms that the add-in is encountering a runtime error, but is not providing proper error handling (which might include a message to the user). The issue needs to be referred to the developer of the add-in.

It could be using CreateObject in the property page OCX and that combination will crash Outlook in the script stopper and get the addin blamed and disabled.

That was going to be the next thing I implement. Is there anything that I will need to be careful about?

In the case of McAfee you can tell it to trust certain code like DLL's and/or OCX's and that usually prevents the problem. With Norton you are out of luck. There is no way to tell it to trust anything and unless they add your code to their internal trusted list (and don't hold your breath for that) it will merrily go about crashing Outlook. The workaround is not to use CreateObject but to get your Outlook reference from PropertyPageSite.Application. That gives you the Outlook object and won't cause the script stopper to crash Outlook and get your program disabled.

How can I know where the error is occuring? Outlook does not crash or display any error at all. However the message comes up when Outlook starts the next time after the addin is used.

Make sure every procedure includes error handling.

I was afraid you would say something like that. Sigh ... Sanjay PS: Thank you for the fantastic help that you provide in the Outlook newsgroups. We would be lost without you and the other MVPs. > Unless you have added your own error handling and logging scheme, it is not > possible to know where the error is occurring.
