Dynamic Distribution Groups and Message Recipient Limit

Question

I understand  that there is a message recipient limit in Office 365 of 500 recipients per message. I also understand that you can get around this with  distribution groups, where each groups counts a 1 recipient. 

I just wanted to confirm  that dynamic distribution groups also only count as 1 recipient. Is that the case?

thanks much

Jamie

Answer 1

Hi Jamie,

The dynamic distribution group will be treated as one recipient but we don't recommand using distribution groups or dynamic distribution groups as a workaround for an increase in daily email recipient limit.

Answer 3

Hi Jamie,

If it just used to increase the number of the recipient in one message for just a few times, this workaround is fine.  If you want to increase the maximum number of email recipients per 24-hour period, we don't recommand this method because the Exchange Online is not intended to be used for Bulk Mail scenarios. Thank you for your understanding.

Best regards,

Alison

Answer 4

thanks Alison -  can you elaborate a bit on why you don't recommend it ?  Client wants to send out company wide email and I was thinking it would be a appropriate. (tenant size is 1,800 users)

thx,
