Hi Add-In Express Team.

We've developed an outlook add-in that adds an panel to the ispector window for appoitments.

Each time it's opened, it loads all items (PostItems) of an specific folder in the inbox an shows values.

After closing the inspector window and opening an new instance a few times, our customers get an "out of memory" exception.

the memory consumption looks like this

Hello Rodrigo,

I would recommend that you comment out blocks of code to locate the issue and identify it.

Do you release COM objects in the code of the add-in?

Hello Andrei,
thank you for the tipp. With your help I identified that it could be an list of objects that i create. I think the problem is that they don't get disposed.

When is the right time to dispose such a list? Is there an event after closing an inspector panel?

Do you release COM objects in the code of the add-in? Yes not everywhere. But nearly 80% in the code.

If you mean an ADXOlForm, then see the ADXOlForm.ADXAfterFormHide event.

If you mean the inspector window, see the InspectorClose (or InspectorDeactivate) event of the Outlook Events component (ADXOutlookAppEvents).
