Had this problem suddenly crop up since the update of one of my accounts not sending mail due to timeouts. I've not changed any passwords or settings since I had it working last. The message is the "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) [my workplace's SMTP server] timed out. Try again." one, and it's preventing me from sending any emails.
Specifics:
- It's one account (my work one: work runs an Outlook/Microsoft mail server).
- My personal account (gmail) sends fine. Both accounts recieve email fine too, so this is just one direction on one account.
Things I've tried:
- Switching my Firewall off makes no difference, so it's not a firewall problem
- It's not that the emails I'm trying to send are too large, one word test emails also don't send
- Extending the timeout time by 3x doesn't help
I also opened a second computer not yet running the latest version - the account worked fine. Then applied the upgrade and that broke things in exactly the same way as described above. So I'm pretty sure this is an issue caused by the upgrade in some way. Not sure if other people with Outlook servers are having the same problem or if there's any workaround available but would appreciate advice.
