Hi,
I wrote an outlook add-in. Sometimes on some computers, the forward, reply and answer-icons in the explorer-mail-list
aren´t shown.
Do you have an idea what can cause this behaviour? My add-in changes nonew of them directly. It´s outlook himself.
On my develop-pc and on my "naked" test-pc everything works fine!

Hello Bernd,

No idea. You can start with restarting that machine. If that doesn't help, try to repair the Office installation.

Hi, here´s the icon problem again :-)
We restarted, we updated, we "switched-cachemodus-off" ... nothing helped. Without my Add-in everything is fine. With my add-in, the icons are "missing".
The customer tries to make copies of an mailitem forwards the new one and this works (somehow).
Maybe it´s a problem that I didn´t release some objects in my explorerselectionchange or somewhere? Can this cause somehow Outlook preventing vom refresh its list of mailitems? If so, I will search for it ..

I've never met such a behavior myself so I can't answer this question.

Nevertheless, cleaning the code is always for the best.

If you access Office events through Add-in Express components, you shouldn't bother about COM classes passed to your code as parameters of an Office event: Add-in Express releases such COM object immediately after the event handler completes.

Also check if your code gets unhandled exceptions.
