We make use of 'autodiscover' technology so that in the majority of cases, Microsoft Outlook can set up your account for you with only an email address and a password. This means that you shouldn't need to enter server information. Here is some more options about our setup options.
If automatic setup failed, you can choose Manual setup or additional server types to enter your settings manually. Use these settings:
Account type: IMAP
Incoming mail server: imap.stackmail.com
Incoming server port (IMAP): 993
Use the following type of encrypted connection: SSL
Outgoing mail server: smtp.stackmail.com
Outgoing server port (SMTP): 465
Use the following type of encrypted connection: TLS
When setting up your account, please choose More Settings > Outgoing Server and check the box for 'My outgoing server (SMTP) requires authentication'.
If you experience any problems with the connection or receive a certificate warning, please disable SSL/TLS encryption and change the incoming server port to 143.
