Exchange365-sending limit options

[Ron Gaster]

Hello,

Is there an option in Exchange365 to set a block limit for sending mail to more than specific amount of users? 

Thanks

Ron

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.

More details here - Exchange Online Limits.  I am not aware of being able to lower these limits for specific users.

No it's not possible to change default limit (500) in Exchange online and it's only support in exchange on-premises
