GAM now supports Google Calendar Management with the ability to modify Access Control Lists (ACLs) for calendars and to add, list and remove calendars from a users Google Calendar display. GAM can work with user primary and secondary calendars as well as resource calendars.

All Google Calendars have an email address associated with them. All users who have the Calendar service enabled have a primary calendar identified by their email address. Secondary calendars created by or for the user have a special calendar email address which can be learned with the gam user <username> show calendars command. Resource Calendars also have a special email address that can be learned with the gam print resources command.

Modifying and Viewing Calendar Access Control Lists (ACLs)

Viewing a Calender's ACL

Syntax

gam calendar <calendar email> showacl

Prints the ACLs for the given calendar. The ACL list will show who has access to the calendar and what level of access they have.

Example

This example displays the Calendar ACLs for [email protected]

gam calendar [email protected] showacl

---

Adding Users to a Calendar's ACL

Syntax

gam calendar <calendar email> add freebusy|read|editor|owner <user email>

Gives user email the desired level of access to the given calendar by adding the user to the ACL. freebusy allows the user to see only times whe n the calendar is busy without showing event details. read gives the user rights to view but not edit the calendar. editor gives read/write access to the calendar but not ACL or settings modification rights. owner gives the user full access to the calendar with the ability to modify the ACL and calendar settings.

Note: The special users domain and default cannot be added to a calendar, they can only be updated or deleted by GAM (see below)

Note: giving a user rights to another calendar adds that calendar to their list of calendars automatically. A separate command to add the calendar should not be necessary.

Example

This example gives Bob editor access to Joe's primary calendar.

gam calendar [email protected] add editor [email protected]

---

Updating a User Entry in a Calendar ACL

Syntax

gam calendar <calendar email> update freebusy|read|editor|owner <user email>

Update the given user's rights to the given calendar. The user should already have explicit access to the calendar. This command will upgrade (or downgrade) the user's access to the desired level of freebusy, read, editor or owner.

Note: the special users domain and default can be used instead of an actual user email address to modify public sharing of the calendar. domain applies to all users in the Google Apps organization. default applies to anyone with a Google account (even @gmail.com) and is limited to read or freebusy. Note that your Calendar control panel settings may prevent read sharing of calendars outside the domain in which case you'll get an error trying to set default to read.

Example

This example upgrades Bob to be owner of Joe's Calendar:

gam calendar [email protected] update owner [email protected]

This example allows anyone with an account in your domain to edit the given resource calendar (including delete others appointments!).

gam calendar example.com_436d6e646572656e6365526f6f6d732d3239352d3372642d5164616d536d6974682d38@resource.calendar.google.com update editor domain

This example allows anyone with a Google account to view Bob's calendar

gam calendar [email protected] update read default

---

Deleting Users from a Calendar's ACL

Syntax

gam calendar <calendar email> delete user <user email>

Removes user email rights to the given calendar. Note that the user may still have some level of rights (freebusy or read) to the calendar based on the default level of access to calendars set within the domain.

Note: deleting the domain and default users disables public sharing of your calendar. domain applies to everyone in your Google Apps domain while default applies to everyone with a Google Account.

Example

This example removes Bob's direct rights to Joe's calendar

gam calendar [email protected] delete user [email protected]

These two examples remove all public sharing of Bob's calendar. Only those with explicit rights will be able to see anything (including freebusy):

gam calendar [email protected] delete user domain
gam calendar [email protected] delete user default

Viewing and Modifying a User's List of Calendars

Showing the Calendars a User Has Listed

Syntax

gam user <user> show calendars

Lists the Calendars the user has listed in their Google Calendar.

Example

This example lists the calendars that Bob has added to his Google Calendar app

gam user [email protected] show calendars

[email protected]'s Calendar List
  Name: [email protected]
    ID: [email protected]

Deleting a Calendar from a User(s) List of Calendars

Syntax

gam user <user>|group <group>|ou <ou>|all users delete calendar <calendar email>

Removes the given calendar from each of the users' list of calendars. Deleting a calendar from a user's calendar list does not change ACLs on the calendar, it simply removes it from the display.

Example

This example removes Joe's calendar from Bob's display of calendars.

gam user [email protected] delete calendar [email protected]

---

Adding a Calendar to a User(s) List of Calendars

Syntax

gam user <user>|group <group>|ou <ou>|all users add calendar <calendar email> [selected true|false] [hidden true|false] [reminder email|sms|popup <minutes>] [notification email|sms eventcreation|eventchange|eventcancellation|eventresponse|agenda] [summary <summary>] [colorindex <1-24>] [backgroundcolor <htmlcolor>] [foregroundcolor <htmlcolor>]

Adds the given calendar to each of the users' list of calendars. Adding a calendar to a user's calendar list does not give them any rights to the calendar that they didn't have before. If the user does not have rights to the calendar, use the ACL command above to both grant them rights and add the calendar to their list of calendars.

The optional argument selected determines if the calendar is selected in the user's list of subscribed calendars by default. The optional argument hidden determines if the calendar is hidden from the user's list of subscribed calendars. The optional argument reminder sets the default reminder type and time for calendar events and can be repeated. The optional argument notification sets the default notification type for calendar events and can be repeated. The optional argument summary overrides the calendar's default name. The optional argument colorindex sets the calendar entries colors. Index colors can be viewed here. The optional arguments backgroundcolor and foregroundcolor manually set the calendars colors.

Example

The following example adds Bob's calendar to Joe's list of calendars without it being selected in Joe's calendar display.

gam user [email protected] add calendar [email protected] selected false

---

Updating a Calendar in a User(s) List of Calendars

Syntax

Update how a given calendar is displayed in a user's list of calendars. The optional argument selected determines if the calendar is selected in the user's list of subscribed calendars by default. The optional argument hidden determines if the calendar is hidden from the user's list of subscribed calendars. The optional argument reminder sets the default reminder type and time for calendar events and can be repeated. The argument reminder clear clears all reminders from the calendar. The optional argument notification sets the default notification type for calendar events and can be repeated. The argument notification clear clears all notifications from the calendar. The optional argument summary overrides the calendar's default name. The optional argument colorindex sets the calendar entries colors. Index colors can be viewed here.
