MC259845: Teams meeting invite recipients limit from Outlook

We’re making some changes to limit the number of individual recipients allowed for scheduling a Teams meeting from Outlook (Win32 and Win64 client only at this time). We will apply this limit for meetings created with more than 750 recipients in the invite. This limit does not apply to the content of Distribution Lists and therefore we encourage users to use Distribution Lists when inviting a large number of attendees to a Teams meeting.

MC259845: Teams meeting invite recipients limit from Outlook

Updated August 10, 2021: We have updated the message below to clarify this impacts Win32 and Win64 clients.

Affected Workloads

  • Microsoft Teams

When will this happen

We will roll-out this change beginning in late June and expect to complete by late September (previously late August).

How this will affect your organization

Users using Outlook (Win32 and Win64) will see an error message dialog when trying to schedule or reschedule a meeting with a number of attendees larger than the new 750 recipient limit and will be required to reduce the number of recipients or user Distribution Lists to send the meeting invite.

Note: If using a client other than Outlook (Win32 or Win64), extra attendees will be automatically dropped.

What you can do to prepare

You may consider updating your training and documentation as appropriate.
