Office 365 (iOS 7) - Respond to Invitations

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result.

Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?.

The following document explains how to respond to an event invitation using the iOS 7 Calendar app (iPhone, iPad, or iPod Touch).

Important: It is recommended that you perform this action using Outlook on the web. The information below is based on Microsoft's recommended use of mobile devices when it comes to interacting with calendars. For best results, Microsoft recommends that people who schedule events with one another use the same calendar client. The majority of calendaring issues involve events with attendees, which may not get updated correctly if the organizer or any of the attendees take action on the meeting via a mobile device. View best practices document for further details.

If you have been invited to a meeting and you have enabled "New Invitation Alerts" in the iPhone Settings, when you next open iPhone Calendar after the invite has been received on the iPhone, a pop-up alert will appear saying "Event Request Notification: " with the event details listed below.

The main icon for the iPhone Calendar located on the homepage will display a red circle with the number of invitations at the top right corner. In the iPhone Calendar application an Inbox button at the bottom-right of the iPhone Calendar display will be modified to indicate the number of invitations iPhone Calendar has received. If there are unviewed invitations, the number of unviewed invitations will show in parentheses after this Inbox button.

On the calendar display, events with invitations to which you have not responded to appear colored gray.

When you Accept a meeting invitation, the event stays in the calendar to which it belongs and iPhone Calendar displays it in the appropriate color. When you respond Maybe to an invitation, it is removed from the Invitations list. The color in iPhone Calendar's display changes to indicate its pending status to the color of the calendar with gray diagonal lines through it. See "Tap on a gray-colored event" below to see how to change your response status after you have selected Maybe as a response to an invitation. When you Decline a meeting invitation, the event disappears completely. iPhone Calendar provides no mechanism to retrieve or view declined events, even if "Show Declined Events" is turned on. Once they are declined they are 'gone' and cannot be seen again on the iPhone. Acting with appropriate caution is advised.

Note: you cannot Decline if using an iPad with iOS version 9.1 or above. You will have to Decline in a different client.

You can respond to invitations in several ways:

Use the Meeting Invitation Notification display

Use the Inbox button

Tap on a gray-colored event
