Two things you can check:

  1. Disable your anti-virus application, and then try again.

  2. Check your IMAP settings. Go to Menu > Tools > Accounts and click on the IMAP tab. Make sure you have the correct combination of port and security policy. For port 993 select Use SSL/TLS on special port (legacy), and for port 143 select Use SSL/TLS if available
