- you're sending emails to people who haven't opted to receive them

Change your email password and run a full virus scan on all devices that access the email. If this doesn't work, contact us to check to see if you are on a bad sender list.

Error 0x800CCC0E - Cannot connect to server
Your mail client is unable to connect to your mail server.
Assuming that your connection to the internet appears to be working fine, you should first check the service status in your area to see if there are any intermittent outages or problems with the email service.
If there are general problems with the network in your area, this may be preventing you from being able to use our services as normal.
If there are no reported problems with the service status in your area then the most likely culprit is the set-up of the account details in your email client. If your email is with us check your set-up.
