Unable to send Blueyonder emails from Outlook

In the last few days I lost the ability to send emails via my Blueyonder account using Outlook (on Windows 10). It prompts me for my password every time I send/receive. Incoming emails are arriving OK. I have the same problem on both a desktop and laptop, both running Outlook and both connected to the same Blueyonder account. This was all working fine until a few days ago. Webmail also works (so I know I am using the correct password).

I've tried removing and re-adding the mail account from Outlook but it didn't help.

Can someone please advise on how this can be fixed?

Re: Unable to send Blueyonder emails from Outlook

Try opening a command window and enter the following

curl -v smtps:// -u username:password 2>&1 | findstr "235 VM"

Replace username with your full email address and password with your password (Note you must remember to leave the : between the two).

You should either get:

< 235 2.7.0 ... authentication succeeded

or some error code

< 535 5.7.8 Authentication Credentials Invalid (VM300) - If the latter the VM code will prove useful.
