How to configure my email client?

Please use the following mail servers to configure your mail client (e.g., Outlook, Thunderbird, Apple Mail, or a mobile device):

Incoming Mailserver IMAP
imap.openxchange.eu
Port: 993
Security: SSL
 
Outgoing Mailserver SMTP
smtp.openxchange.eu
Authentication same as incoming, user + password
Port: 587
Security: TLS or STARTTLS 

Note: The outgoing mail server (SMTP) requires authentication using the same credentials as the incoming server.

IMPORTANT: We recommend using the following ports and encryption methods to connect to the mail servers:

• POP: 995 SSL
• IMAP: 993 SSL
• SMTP: 587 TLS or STARTTLS

TLS/SSL versions 1.0 and 1.1 for POP, IMAP, and SMTP are no longer supported by the Open-Xchange mail service. Please use an email client that supports TLS/SSL v1.2 or later, such as Outlook 2016, MacMail on macOS 10.11, Windows 10 Mail, Android 5, or iOS 9 and above.
