How can I maximize the number of recipients per message on Microsoft Exchange 2013

The limited number of recipients per message our users have is 500. And one of our users needs to send an email weekly to more than 500 and I was wondering if there's a way to do that. 

Thanks!

Thanks for the reply, Salva. I have seen this article before. But I'm not comfortable using the Shell cmd and the EAC Configuration is N/A. Any suggestions?

The shell command would be:
Set-Mailbox -Identity "John Smith" -RecipientLimits 600

You have to deal with EMS anyway since you are exchange admin. You have to look at Organizational, Connector, Server and User limits to make sure that limits are set correctly. MikeV demonstrated how to set limit under specific mailbox. Do the same for other configuration fields. Anytime you can use -whatif parameter with EMS to make sure that you are right.

Hi,

To manage exchange, both EAC and EMS (Exchange management shell) are very important, you must learn one of them at least.

The document Slava Fedenko provided explains very well about message size limit in Exchange 2013. Especially the precedence for message size limits is very important.

MikeVATXs command will solve your problem.

Best Regards.
