The Outlook/Exchange provider addin has been checked every time I have installed, repaired, or changed the Avast Anti-Virus program. It never shows up in the Outlook addin list after isntalling, repairing, or changing the Avast Anti-Virus installation. I don't know why, but it is never there. But, as I stated in an earlier post, it was there for a while on my wife's computer, but then it disappeared for no reason and I haven't been able to get it back. It doesn't show to be a disabled item in Outlook. I don't have any idea why, after everything that I have tried, it still does not show up in Outlook addins. If it would show up there, it would run when Outlook was open.
