Been working on trying to find this answer for a LONG time...here is the best I can do for you..
Open up OUTLOOK EXPRESS...then click on
TOOLS
ACCOUNTS
MAIL
PROPERTIES
ADVANCED
Once you are in ADVANCED you will see your present port settings. Just click on the one you want to change (this will hilite it) click on delete and then put what number you want in the box. Go below and click on APPLY...
This should do it??
NOTE: Please remember to pick one of your answers as the best answer by clicking on
the THUMBS UP at the end of that particular answer...otherwise Yahoo will have to do it for you and they have enough to do....thanx
