How to add a DreamHost email address to Outlook

See the official Microsoft 365 support page for more information on setting up and adding an email account to Outlook:

Choosing an account type

When the Choose account type page opens in Outlook, you can select either POP or IMAP. IMAP is recommended.

IMAP Account Settings

On the IMAP Account Settings page, enter the following Incoming and Outgoing mail settings:

  • Server — This is your DreamHost mail server name. The example above uses imap.dreamhost.com for the incoming server. If you'd prefer a POP connection, you can use pop.dreamhost.com instead. The outgoing server is always smtp.dreamhost.com.

    Make sure you only enter your DreamHost mail servername. Do not use a subdomain such as mail.example.com. You may get an insecure warning if you use the wrong mail hostname.

  • Port — If you chose IMAP, the secure port is 993. For outgoing ports, use 465 or 587.

    Port 465 with SSL is recommended, however, some email clients are unable to use this port. If you are unable to use port 465, the next best option is port 587 using STARTTLS.

    DreamHost does not support Secure Password Authentication (SPA), so make sure to turn off the SPA option for both incoming and outgoing settings.

  • Encryption — Select SSL/TLS from the drop-down menu.

Adding or removing IMAP folders

Instructions for adding or removing IMAP folders can be found in the following Microsoft documentation:
