LionMail logo

LionMail is Columbia's state-of-the-art email, contacts and calendaring system, powered by Google. It provides a secure and convenient way to send and receive mail from any location using just a web browser such as Chrome, Firefox, Internet Explorer or Safari. The supported browsers are the current and the previous release of your preferred browser.

All Columbia University Morningside students, faculty and staff have LionMail, though some administrative departments have opted to use Outlook Exchange. CUMC students, faculty and staff use the CUMC email system. CUMC affiliates do not use LionMail.

LionMail setup for your non-Gmail email client

An email client is a program used to access and manage your email.
Please remember that the Gmail web interface is CUIT's only fully supported method for reading LionMail.

Before you set up your email client (required)

The Allow less secure apps setting is set to ON.

After your set up your email client

LionMail can be configured to allow unlimited messages, which works well in the Gamil web interface, but can create syncing delays if you use an email client. This can be reduced by setting the folder limit size to a suggested limit of less than 1,000 messages.

How to set folder size limits:

  1. Log into your LionMail account in the Gmail web interface.

  2. Click the gear in the upper-right corner and select Settings.

  3. Select the Forwarding and POP/IMAP tab at the top.

  4. In the IMAP Access section, under Folder Size Limits make sure Limit IMAP folders to contain no more than this many messages is selected, then choose the preferred limit from the drop-down menu.

We suggest hiding certain folders to prevent your device from syncing GBs of mail.

  1. Log into your LionMail account in the Gmail web interface.

  2. Click the gear in the upper-right corner and select Settings.

  3. Select the Labels tab at the top.

  4. Make sure Show in IMAP is not checked for any folder or label you want to hide from your device or email client mailbox. Since archiving a message in your email client moves it to All Mail in LionMail, we suggest that you hide (uncheck) All Mail.

Settings section of Gmail web interface

All Google accounts, including LionMail, have a limited amount of bandwidth, and this extends to bandwidth used for account synchronization. If you exceed the bandwidth limit, your account may be temporarily suspended. In this case, you can still log into your LionMail account with the Gmail web interface.

Google provides specific information on the bandwidth limits as well as recommendations to avoid reaching the bandwidth limit for syncing.

The default user experience in LionMail when accessing it via ActiveSync (iPad/iPhone) or IMAP (Thunderbird, Apple Mail, Outlook or Blackberry) is different than is when you access LionMail via the Gmail web app. We have created a table comparing how actions in your device or software will affect your LionMail account.

Configure your email client to offer UNIs and names from the Columbia directory by adding LDAP (Lightweight Directory Access Protocol).

Please note that Columbia LDAP is not available for Apple Mail. If you prefer to use an email client on your macOS computer, CUIT recommends that you use Mozilla Thunderbird.
