Thank you. My email was was back working and synching with Outlook after the major outage. It's today the problem has occurred and it seems to be something to do with last nights maintenance. I only have one VM email address and have checked my passwords and settings and they are correct. The cURL command produces the following:
C:\Users\bridg>curl -v imaps://imap.virginmedia.com/
* Trying 84.116.6.19:993...
* Connected to imap.virginmedia.com (84.116.6.19) port 993 (#0)

curl: (21) Quote command returned error
I don't really understand what this means but seems that there is an error in the IMAP command received by the server. As the settings in Outlook are correct I'm not sure why that is. But you are probably right that I should ask for help from forum admin team. I should perhaps post this as a new topic tomorrow.
