Error Message: "not a valid outlook plugin"
At one point this was working. I closed the tool bar once, however, and have not been able to reinstall or access the plug in. It does not show up in the trust center, and when I try to add it, I get the above message that the .exe file is not a valid add-in. Any ideas? The microsoft.net etc is all up to date. Running on a 64 bit. Recently had a itunes update that apparently added something to outlook (?!) but other than that, no outlook addins.
