This can happen if you access your emails in more than one way e.g. via webmail and Outlook. If you use more than one method to collect your email
you may find your emails disappear and are marked as unread when you have already read them. The solution is to change your incoming mail server to use IMAP.
There are two ways your devices and clients can communicate with UkMailExchange:
- A one-way communication path (POP). Your device asks us for data and pulls it from our servers -- but that's it. Things you do on your device have no effect on the server.
- A two-way communication path (IMAP). Unlike with POP, your devices talk back to our servers and sync your changes automatically with IMAP.
