Yesterday I tried to send emails and I got an error message. I could
receive but not send. I tried all the usual things several times:
turned off the computer, turned off my router and cable modem,
checked all my connections, started fresh. The problem persists. Is
this a problem with Outlook?

Make suer you''re properly authenticating to your outgoing server. Since
you didn't think it was important to state your Outlook version, no one can
tell you exactly how to do that.
