Morning @morag11 

Thanks for coming back to the community. 

I'd recommend running a virus/malware scan on your device and updating your password. Once you have done this and if you still have the same error, please send me a private message with a screenshot of the error message/non-delivery report and the email address affected and we will help you further.

Speak to you soon

Leanne.
