LionMail (Google) Calendar

LionMail includes a sharable calendar, LionMail Calendar (Columbia's implementation of Google Calendar). LionMail Calendar allows you to create events, set reminders, and list tasks. Calendars can be shared between friends, colleagues, and teams, and are accessible via Android and iOS mobile devices.

Calendar can be found in the square Google apps grid in the upper-right corner of LionMail











  • Collaboration: Work with others by creating a designated team or project calendar
  • Share: Provide those you know with access to see when you are free or busy, or delegate the ability to see all event details and create events from your calendar
  • Search: Google's infamous search functionality can comb the title and description content of your past and future events
  • Task management: Use Tasks (to-do list) and Reminders (alerts for events set to notify you in advance) to keep you on schedule
  • Calendar mobile app: Get Google Calendar on your smartphone or tablet (Android or iOS) for quick reference

Please remember that the Gmail web interface is CUIT's only fully supported method for using LionMail Calendar. The supported browsers of LionMail Calendar 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.


Columbia University is committed to ensuring equal access to information, programs and activities through its technologies, web pages, services and resources for all its constituencies, including people with disabilities. The infrastructures behind LionMail and LionMail Calendar are fully compatible with client software such as Outlook, Thunderbird and Apple Mail; these clients can in turn be used with common screen-reader software.

Attention Faculty: At no time can LionMail Drive be made a course requirement.
Please follow our general LionMail accessibility guidelines for making your Google Documents accessible to people with disabilities. The Google Administrator Guide to Accessibility provides further information on accessibility and Google Apps, including Google Drive.

If you encounter any difficulties or have questions about using assistive technologies or creating accessible documents with Google Drive, please contact CUIT by calling 212-854-1919 or sending an email to [email protected].

Sharing and delegating your calendar

There are several permission options of sharing for Google calendars. They are:

  • See only free/busy (hide details) — ideal for group- or department-wide sharing, allowing others to identify times when everyone is free. By default, internal LionMail this setting is ON.
  • See all event details — ideal for close friends/colleagues and departmental administrative assistants, allowing them to see where you are scheduled to be at any given time.
  • Make changes to events — ideal for delegating partial calendar management to administrative assistants, allowing them to create, accept, and decline meetings from your calendar.
  • Make changes and manage sharing — ideal for delegating full calendar management to administrative assistants, allowing them to create and respond to meeting invitations from your calendar, as well as the ability to share your calendar with others on your behalf (for example, while you are on vacation)

Your delegate cannot change your calendar settings, such as time zone or language, or have access to your contact groups at any of these permission options.

For external sharing options LionMail Calendar options for primary calendars

    • Restore or permanently delete events from the calendar's trash. 
    • Find calendar time zone setting. 
    • Subscribe to email alerts when events are created, changed, canceled, responded to, or coming up.

  • Share all information, but outsiders cannot change calendars — Find details for all events except those marked as private.
    • Find the time zone setting for the calendar. 
    • Subscribe to email alerts when events are created, changed, canceled, responded to, or coming up.

How to share or delegate calendar access

Log into your LionMail account and then select Calendar from the app grid in the upper-righthand corner of your email inbox.

After you've opened your calendar, find your name in the left-hand column under My calendars.

Navigate to the right of your name and click on the three dots that appear: Options for [your name]. Select Settings and sharing.

Scroll down to the Share with specific people section and select Add people

Enter the email or name of the person(s) or Google/LionMail Groups that you would like to share your calendar with and select the permissions option that you would like to give them.

Click Send to complete sharing your calendar.

The recipients will receive an email notifying them that you have shared your calendar with them, the level of permission you have given them, and a link to click on that will bring them to your calendar. They can access your calendar at any time in their own LionMail calendar by looking for your name under My calendars or Other calendars, depending on the permission you gave them. 

If you have given Make changes and manage sharing permission, your delegate will see your calendar under the My calendars list on the left. If you have given any of the other levels of permission, your delegate will see your calendar in their Other calendars section.

Yes. Please follow these steps:

In CourseWorks
  1. Click Calendar under My Workspace on the left.
  2. At the top click Subscribe (User defined feed).
  3. On the next screen, enter a name for your calendar and make sure Enable Subscription? is checked.
  4. Click Save. Copy the Subscription URL that appears. (To copy, right-click in Windows or Command-C in MacOS). 
In LionMail Calendar
  1. Click the + button next to the "Add a coworker's calendar" field on the left-hand side.
  2. Select From URL.
  3. Paste the copied URL into the URL: box and click Add Calendar. You’ll see your New Courseworks schedule listed under Other Calendars. The name by default will start with “https://newcourseworks...” 
Naming your new CourseWorks Calendar in LionMail Calendar
  1. Click the three dots to the right of the calendar name and select Settings.
  2. Enter a new name (for example, "Classes" or "My Class Schedule") for the calendar and click the Save button.
  3. Go back to the main Calendar screen and you’ll see your calendar listed with its new name.

Anytime you mark an event as "all day" in your calendar, you must modify the visibility option (near the bottom of the event) to "busy" rather than "free", which enables anyone who shares your calendar to see it as blocked.

Even if your default visibility is "busy", Google calendar automatically changes all-day events to "free" because people often use "all day" to indicate holidays, birthdays, announcement dates, go-live dates, etc. These events don't necessarily preclude you from doing other things, so Google automatically changes you to "free".

You can create multiple calendars, share them with different groups of people, and show/hide them as you need. This is particularly useful for documenting project milestones and documenting vacation schedules for a team.

To create a new calendar:

  1. Open your LionMail calendar
  2. On the left-hand side, click the + button next to the Add a coworker's calendar field
  3. Select New calendar
  4. Provide a name and description (optional)
  5. Click Create calendar
  6. Your calendar can be found in the My Calendars list on the left-hand side of LionMail Calendar. You can share this calendar by clicking the three dots (Options) to the right of the calendar's name, and then selecting Settings and sharing.

To customize or easily distinguish your own calendar from another calendar to which you have access, choose distinct colors for each calendar.

Change the color of a calendar by navigating to the right of a person's name, clicking on the three dots that appear: Options for [calendar holder's name], and selecting a new color. If you would prefer a more muted color than the bold options, you can pick a custom color by clicking on the + sign at the bottom.
