Outlook "forgot" a distribution list I use quite often, so I had to rebuild it. Ugh! Over 100 names! After all that work, I can't use the darn thing, getting an error code 554 5.7.1. I saw a forum where one of the techs thought it was related only to a surface book, but I'm using a PC. HELP!!!

    I haven't taken a look at the link--afraid it might contain a virus. Earlier this week my distribution list worked just fine. I had to rebuild it when Outlook "forgot" it. Though with all the same names, the distribution list no longer works. Seems like nothing really changed except I can't send email using it.
