My email is affected differently on a daily basis.  Some days it's incoming that won't work, and other days it's outgoing.

Something is going on "behind the scenes" that alters my settings. I do not change email settings or other settings.

The current settings recommended by our "Comcast" server is as follows:

outgoing suggested by CC today is = 587 ( yesterday suggested setting was 465 ) ?

incoming suggested by CC today is 110

SAME PC = My husband's email is never affected. 

Anyone that can assist in some solution to this issue would be appreciated.

Thank You, B
