If your email has suddenly stopped working, work through these checks before changing anything major.
The aim is to work out whether the problem is with the mailbox itself, one device or one particular message.

If messages appear to be missing, check:
Sometimes the email has arrived but has been moved somewhere unexpected.
Before you know what the problem is, don’t:
If you’re unsure, stop there and get in touch.
Send me:
If your normal email account can’t send, use the Contact form or another working email address.
Don’t send me your password.
