Outlook 2016 Client recipient limitations RRS feed

  • Question

  • Hi,

    Are there any E-mail client specific limitations about how many recipients you can have in an E-mail?

    In this documentation its said that Exchange Online has a recipient limit of 500 per message.

    But I'm wondering if there are any client specific recipient limitations for Outlook 2016 Windows and Mac?

    Best Regards,

  • Hi Niilo,

    According to my research, Outlook itself doesn’t hold a limit for the amount of addresses that you can send to within a single email. ISPs or corporate mail administrators usually have one of the following limits set or a combination of them, such as the limitation of Exchange Online mentioned above.

    Hope the information is helpful to you.
