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?
