Outlook Add-In dev. problem

[szukuro]

I'm writing an Outlook Add-in using VSTO 2005. However there's a
slight problem; when I attach event handlers to the CustomAction event
of MailItems sometimes the method doesn't get called. There are cases
when attaching them more times (at run-time) overcomes this problem,
however sometimes it looks like they don't "stick", meaning I click a
custom action button once and it works, then I click it a second time
and now the handling method does not get called. I even fail to
recognize the pattern in this random behavior.
Has anyone else faced similar issues, and if so how do I overcome them?

Hello,

You do know the answer: you should reconnect the event handlers on-the-fly.
Here, in Add-in Express, we don't know the pattern too.

In addition to Andrei's advice also make sure all your event handlers are
declared at a class level scope so they don't go out of scope or get garbage
collected while you still need them.
