I have had a host of issues with Outlook 2003 and Outlook 2007 on both Windows XP and Windows 7 platforms, and the Ironport Plugin.
I have tried previous versions as well as the most current (that I could find) OutlookDesktopFlag_6.5.1-006.msi and about 60 % of the time the "sendSecure" add in will not be there. I usually have to dig into the Outlook add-ins section and manually browse & select it, for it to show up.
Also after a period of time, the add in can disappear.
Are there any known incompatibilities with certain MS KB patches, etc, that could be causing this?
Out of roughly 100 users I have rolled this out to, we have had issues with 70 of them either up front, or with the add in disappearing.
Anyone else experiencing these issues?
