The last 2-3 days Outlook started to misbehave and ask for my id and password during a session. I changed the security settings several times and managed to get and send emails, but they bounced several times. Today I got in touch with the comcast support line (phone support) and spent about 1/2 hour getting the point across that I had tried all the things that she was recommending.
The last thing I was told before I hung up in disgust was that Microsoft had acknowledged a problem with Outlook and was working on it for Comcast. I was supposed to use the internet joke mail provided by them until Microsoft got things sorted out. I don't know for sure, but its my guess that there is absolutely no people at Microsoft working on a Outlook problem for Comcast one way or the other. I believe that they (Comcast) are just upgrading or changing something and dont want to support or deal with the issue.
I could put up with something like " you will have email back by tomorrow or this week" but to BS me with the stuff about Microsoft working on security bugs just for comcast is just tooo much.
