This option is available in Outlook for Windows, Outlook for Mac, Outlook on the web, and. If you don't need to know who responded to your meeting invitation, you can turn off responses.

For meetings organized by someone in an Exchange on-premises environment, clients continue to use the legacy recipients property for both the list of recipients and the list of responses. Administrators in Exchange on-premises environments can choose whether to have a maximum number of recipients and, if selected, what the maximum should be.

This article only applies to meetings organized by people using Microsoft 365. In addition to changing the maximum, Outlook will stop tracking new responses - which includes adding the responding attendee into the list of recipients - once the number of recipients is close to 2,500.Įven when close to the 2,500 recipient maximum, attendees who are forwarded the meeting or who are individually added to the invite list by the organizer will still be added to the list of recipients to ensure that they receive any future updates to the meeting. This is because the meeting organizer would send the invitation to a distribution list (1 recipient), and as members of the distribution list responded to the meeting, each person was individually added into the recipients list to track their response (eventually causing the recipients list to surpass 500 after enough people responded). These types of meetings were more likely to hit the recipient limit as attendees responded to the meeting. Meetings sent to groups or distribution lists primarily benefit from this change. What type of meeting benefits from this change? Note that when you send an email message or a meeting invitation to a distribution list, the distribution list only counts as 1 recipient. This new maximum applies only to meeting messages. In Microsoft 365, the maximum number of recipients on any outgoing meeting message - whether a new invitation, a meeting update, or a meeting cancellation - was previously 500.

To prevent this from happening, we’ve changed the recipient limits in Microsoft 365 when sending meeting invitations or updates. These changes ensure that you’ll always be able to update or cancel the meeting and still see the list of attendees and responses. If hundreds of people responded to the invitation, you might have been unable to update your meeting. This occurred because Outlook lists each person who accepted, tentatively accepted, or declined on the To line of the invitation for response tracking, and there's a limit to the number of individuals who can be listed on an email message or meeting invitation. In the past, when you used Microsoft 365 to send a meeting invitation to hundreds of attendees, you might not have been able to update or cancel the invitation. The changes don't affect smaller meetings. Note: These changes apply only to meetings created in Microsoft 365 that include hundreds of attendees.
