Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

Hi @Laura Wheatley ,
Sounds like you are having trouble with logging into your email account, right? If so, to confirm if this is a client issue, please try to log into your web mail and see if your email account could work fine.
If you can get the same error on your web mail as well, I'm afraid that the issue might be related your email account itself, please try to contact the administrator of your mailbox for help.
If everything can work fine on your web mail, we could refer that this is an issue related to your mail client. So, what mail client are you using right now? The win10 Mail app or Outlook desktop client(such as Outlook 2013 or 2016)?
If you are using the Win10 Mail app, you could check the link @Anonymous mentioned above to modify your sync settings on Windows 10 and see if the issue could be resolved.
If you are using Outlook desktop client, corrupted profile might lead issues like this, so please try creating and using a new Outlook profile via Control Panel > Mail > Show profile and see if there is any difference.
If you have any update about this issue, please feel free to post back.
