I have been troubleshooting based on reading past posts about similar
problems, but have run out of ideas would please appreciate some assistance.
Windows Mail e-mail was working fine until today; but now I cannot send or
receive without errors. It has worked briefly but not for more than a few
minutes. Every minute, I receive a message saying "Your SMTP server has not
responded in 60 seconds...." and lists my Account and Server. I receive the
following error when trying to send e-mail. I replaced my acct and server
info w/generic for this submission:
"The connection to the server has failed. Subject 'Read: Test again',
Account: 'mail.company.com.com', Server: 'mail.company.com', Protocol: SMTP,
Port: 1025, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E"
I just disabled some protections on my TrendMicro security. I have Charter
high speed and wireless router, both of which I have reset, turned off and
unplugged/replugged several times. I changed the outgoing port from 25 to
1025 several times; it was recommended by my Web/e-mail host upon setup to
use 1025.
Also, when trying to send an e-mail to myself at one point, Windows Mail
requested a read receipt, which is not a feature I have enabled on my system.
Please help! Thank you.
