More information

When a meeting organizer updates a meeting by adding or removing an attendee, the following notifications are no longer displayed in Outlook on the web:
- Send updates only to added or deleted attendees
- Send updates to all attendees
These options were removed from Outlook on the web, and the code logic was moved to the server. Therefore, the server makes the decision about whether to send the update to all attendees or only to attendees that are added or deleted.
Note
This change affects only Outlook on the web. These notifications are displayed in Microsoft Outlook when a meeting organizer adds or removes attendees from an existing meeting request.
Two kinds of updates
There are two kinds of updates:
- An update that requires a response
- An informational update

Note
By default, updates are not sent to all recipients but only to the specific adjusted recipients (added or deleted attendees). If the attendees list contains an unexpanded distribution group, any updates are sent to all recipients.

Updates are sent to all recipients for single and recurrence meetings when one of the following items is changed:
- Location field
- Message body
- Attachments
These updates are informational, and they do not require the recipient to process (accept/decline/tentative).
Updates are sent to all recipients to be processed when one of the following changes occurs:
