I'm having a tough time troubleshooting this. On a handful of customer machines, my VSTO add-in works fine 99% of the time but occasionally the Outlook process becomes unresponsive and crashes. After the process dies and the program is restarted, there's
an error message, "Outlook experienced a serious problem with the '<My Addin Name>' add-in. If you have seen this message multiple times, you should disable this add-in and check to see if an update is available. Do you want to disable this add-in?".
One user didn't seem to be doing anything in Outlook when the process became unresponsive. Another user reported it happened when clicking buttons in my add-in's ribbon controls. I can't seem to rero the problem myself.
I have event logs from a few of the machines, and the only common exceptions I see are like this:
Faulting application name: OUTLOOK.EXE, version: 14.0.7012.1000, time stamp: 0x514a1b69
Faulting module name: KERNELBASE.dll, version: 6.1.7601.18409, time stamp: 0x53159a86
Exception code: 0xe0434352
Fault offset: 0x0000c42d
Faulting process id: 0x1984
Faulting application start time: 0x01d00fcf487df866
Faulting application path: C:\Program Files (x86)\Microsoft Office\Office14\OUTLOOK.EXE
Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
Report Id: f9f4d362-7c02-11e4-b727-ecf4bb39a865
Faulting package full name: %14
Faulting package-relative application ID: %15
And
The description for Event ID 2000 from source Microsoft Office 14 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local
computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Microsoft Outlook
Outlook experienced a serious problem with the '<My Addin Name>' add-in. If you have seen this message multiple times, you should disable this add-in and check to see if an update is available. Do you want to disable this add-in?
And
Add-in execution error. Outlook crashed during the 'Close' callback of the 'InspectorEvents_10' interface while calling into the '<My Addin Name>' add-in.
That last one seems promising but it's pointing to Inspector wrapping code that's boilerplate from this MSDN article: http://msdn.microsoft.com/en-us/library/office/ff973716%28v=office.14%29.aspx . So, I'm not sure why it would have issues.
I saw this thread (https://social.msdn.microsoft.com/Forums/vstudio/en-US/edbdea28-c756-4fe0-9413-c9f55ed870c3/outlook-2010-experience-a-serious-problem-with-crm-2011-addin?forum=crm) with a similar error, but their cause was a conflicting add-in which I don't see on our problem machines.
Let me know if anyone has ideas on how to troubleshoot this. Some of the customers are internal to my company, so that opens some doors. But I'm really hitting a brick wall at the moment.
