Exchange365-sending limit options
Hello, Is there an option in Exchange365 to set a block limit for sending mail to more than specific amount of users? Thanks Ron
No it's not possible to change default limit (500) in Exchange online and it's only support in exchange on-premises
You can refer the following links ( Parameter name is RecipientLimits )

There are limits built-in to Exchange Online with email usage:
"Receiving and sending limits are applied to combat spam and mass-mailing worms or viruses. These limits help to protect the health of our systems and keep our users safe."
That's a 500 recipients limit with a max daily limit of 10,000.
