Office 365 Meeting Invitations and Updates

When an attendee receives an invite to an Office 365 email meeting, the email to accept the invite may include the following information:

• Required and optional attendees
• Location (if selected by organizer)
• Time of meeting
• Recurrence pattern (if applicable)
• Subject
• Email message body (often includes agenda)
• Attachments

Changes that will always send a notification email to the invitee's Inbox:

The following changes will trigger a notification email to the attendee's Inbox:

• Location change
• Time change
• Recurrence pattern change
• Any changes made by the meeting organizer (within 15 minutes of that meeting’s start time) to the meeting subject, body (agenda), or attachments
• The receiving attendee is mentioned, via the @[name] format, in the meeting body
• The attendee has not yet responded to the meeting invite

These types of changes will result in an email notification to the recipient's Inbox, alerting them that the meeting details have been updated.

Recipients will see a No response required option in the message, indicating that no further action is necessary for updating their calendar.

Changes that will automatically update the recipient’s calendar event without notifying the attendee:

The following types of changes will automatically update the recipient’s calendar without requiring them to accept changes:

• Changes to attendees
• Any changes made up until 15 minutes before the meeting start time to the meeting’s subject, body (agenda), or attachments

For changes that meet these criteria, the system will automatically update the attendee's calendar without sending an acceptance prompt or email notification.

Important:

If you need to explicitly notify attendees of these types of changes, it is recommended that you Reply All to the meeting with a message indicating what has been updated, in addition to making changes to the meeting details as usual.
