Sometime Add In don't show up on the toolbar

[Shashi Bhosale]

Hi ,

I am using Outlook 97.

I have writeen a COM add-In in Visual Basic 6.0 for Outlook . I am
registering that dll and explicitly adding in the outlook using Tools-
Options - Other-Advanaced Option- COM Addin. The Add-In shows up on the
toolbar.
But sometimes it doesn't show up, the i will have to remove that add-in and
add it again.
Any idea why it is causing this?

Thanks in advance,

Shashi

Outlook 97 does not support COM addins at all. Support for COM addins was
added in Outlook 2000. Previous versions of Outlook only supported Exchange
extensions, written in Extended MAPI.

I am sorry i have Outlook 2000 only. I have a issue with this 2000 version.

You will have to run in debug mode and see if your On_Connection event
handler is being called. Also, you should check in the registry for your
addin and see what LoadBehavior is set to when the addin isn't available. If
it's not 3 then you have to track down what's changing it from 3 to whatever
it is.
