I have a sparadic issue of Outlook adding "=STMP:" to all my external meeting invitees after the meeting has been setup and saved. I say sparadic because it does not happen to every meeting but when it does, it happens to all external mtg invitees. My original meeting request is delivered without a problem. I am only aware of the problem if I need to send email with Reply All using meeting request or need to update the meeting request. If I update mtg request, I must delete the bogus invitee info and re-add the invitee, from my Contacts. Usually this results in 2 versions of same mtg request, with same time stamp, requiring me to save both versions before I can save updated request. One time I deleted what I thought was the bad version of mtg request and ended up deleting the whole request from just my calendar. All my meeting request invitees are housed in my Contacts and their email address in the Contacts field looks fine.
Today I deleted all email address in AutoComplete with the leading "=SMTP:". Maybe that will help but I'd still like to know why it happened?
