Maximum attendees in a meeting request

Does any one know what the maximun number of attendees are recommeneded when sending a meeting request out via Outlook with an Exchange 2013 or 2016 backend.

Also what is the best practice on sending a meeting request to a DL?

 

I am kind of suprised that the document https://support.office.com/en-us/article/Best-practices-when-using-the-Outlook-Calendar-d93f72d3-2361-4e0d-8d6a-5c4939c17f39 does not offer any guidence on this.

    There's no maximum limit for meeting attendees per se, the default Exchange "recipient limit" however will stop you from sending invite to more than 500 people in a single message. If you use a DG, you can go well beyound that limit.

      VasilMichev I have over 1,200 employees that I need to send a Microsoft outlook calendar invite to. I know Microsoft has a limit of 500 names for outlook calendar invites. What is the best way to get this done without having a ton of bounce back emails because of the limit?

       

      Thanks,

      Jo Ann

        Hi JoAnnTaylor ,

         

        I think this resource may help you: https://support.microsoft.com/en-us/office/scheduling-meetings-with-hundreds-of-attendees-f8cce35d-673e-41a0-8aea-dc5331bb60ed

         

        In Microsoft 365, the maximum number of recipients on any sent item, whether it's a normal email message or meeting invitation, is 500. When you send an email message or a meeting invitation to a distribution list, the distribution list only counts as 1 recipient.

        So if you create a DL with all your employees, you should be able to send a MR to all of them.

        I hope this helps.
