I can receive emails but can't send. I checked the SMTP & SPA settings and
it's not that. It was an acute problem. It worked fine then changed without
changing any settings.
And what does the error message say for the failed send in the
UNIDENTIFIED version of Outlook?
Just because you didn't change anything doesn't mean nothing got
changed. You are only half the equation. The other half is up on the
server. Maybe your e-mail provider changed to requiring a different
port number for SMTP transactions, like changing from port 25 to 587.
Maybe you cannot reach their SMTP mail host because it is down, too
busy, unresponsive, or the route to it is broken. Can't tell without
the error message that you omitted in your post.
If it is a supported e-mail account, what did their tech rep say when
you called them to report the sudden outage in availability to use their
SMTP mail host? Are you on their network for where is the SMTP mail
host (i.e., is it your ISP's mail host)? Or is the SMTP mail host on
someone else's network than your own (with your ISP)?
No one here knows who is your e-mail provider because you did not
identify them. Maybe they are having problems with their service that
someone else using the same e-mail provider would know about the problem
but they would have to know who you use to see if was who they also
used.
"Cannot send now, worked before" gives nothing to go on.
