Max send limit of email enabled security group exchange 2016

Question

Hi,

I'm trying to find out if email enabled security groups are governed by the max recipient list of a user? so if a user has 200 recipients as default and the security group has 300 members can they email all 300? I thought the answer would be yes as they are only sending to 1 email address and exchange does the rest but I have a request to raise the number they can send to in a security group. Any thoughts on how this can be?

Thanks

Answer 1

Groups count as one recipient.

If that is not working, then it sounds as if the user is expanding the list before sending to it.

Answer 2

Hello, @John H,

Welcome to the Microsoft Q&A platform!

Based on your description, I ran a test and successfully sent an email to a secure group with email enabled and members greater than 1, using an account with a recipient limit of 1. Upon testing, all members within the security group received the email, which is consistent with your suspicions. My operations and results are shown below.

1. Use the PowerShell command to set the maximum number of recipients on the sender side to 1.
2. Created a security group in EAC with a membership greater than 1.
3. Members in the security group successfully received the email.

Regarding your request, can I ask if by " raise the number they can send to in a security group " you mean you want to send emails to multiple security groups? If there is any misunderstanding, could you please describe your specific requirements? Please feel free to contact me.

Thank you for your support and understanding.

Best,

Alex Zhang
