Microsoft Outlook Calendar

Microsoft Outlook Calendar is the calendaring and scheduling software used at Ithaca College which can be accessed with the Outlook desktop, mobile, and web browser applications.

Outlook Calendar allows faculty, staff, and students to maintain personal agendas, schedule meetings with each other on an invitational basis, and schedule resources, such as meeting rooms. All faculty, staff, and student personal email accounts, and department email accounts include Outlook Calendar. If only the calendar function is needed, Outlook offers users the ability to create their own additional calendars that can be shared within a department.

Outlook Calendar Resources

Outlook Calendar resources are typically departmental meeting rooms. These rooms can be scheduled using Outlook Calendar. One person is the designated resource owner and has the ability to approve or decline scheduling of the space.

  • There is no distinction between a room and a piece of equipment. They can be "invited" to meetings just like people.
  • The owner of a resource can customize the settings for the account.
  • Resources do not allow scheduling conflicts. If the resource already has an event scheduled for a particular time, no one else can "invite" the resource to another event.
  • Multiple resources can be invited to a meeting.


By default, anyone using Microsoft Outlook can schedule the resource. However, the owner can change this so that:

  • When someone includes the resource as an invitee to a meeting, the owner, or someone delegated by the owner, approves or denies the request,
  • Viewing and scheduling of a resource is limited by permissions to specific people.


In order to view the resource's calendar directly, the owner, or someone delegated by the owner, must give you access permissions.


Only the owner, or someone delegated by the owner, can adjust the settings for the resource. Owners can configure how the resource can be scheduled, including:

  • Automatic scheduling vs. request to schedule
  • Maximum meeting length
  • Whether recurring meetings are allowed

To configure the resource:

  1. Log in to Outlook on the Web at
  2. Click your profile photo in the top right of Outlook.
  3. Click Open another mailbox.
  4. Enter the room resource name (e.g. and click Open.
  5. Click  Settings.
  6. Type Calendar in the Search Outlook Settings box.
  7. Select Calendar appearance.
  8. Click Resource scheduling.
