Limit or Moderate emails with multiple recipients in Office 365

[swapnil joshi]

Hello Team , 

I would like to monitor or set moderation for emails ,

Which have multiple recipients (Inbound-Outbound both)

Wanted to check if we have any provision for same

I would start with Exchange transport rules as that allows you to perform the outcomes you're hoping to (ie. if mail comes for this recipient, send a copy to that recipient - or - if this person sends an email, redirect it to their manager for approval).
Have a look here: https://technet.microsoft.com/en-us/library/jj919238(v=exchg.150).aspx

There are many functionalities that can help you with that, but you need to be more specific - what exactly are you trying to achieve here? In addition to the transport rules as Loryan suggested below, you can impose delivery restrictions by leveraging the corresponding mailbox/group parameters, you can enable the actual "moderation" functionality, you can also take a look at the Supervision functionality: https://support.office.com/en-gb/article/configure-supervision-policies-for-your-organization-d14ae7...

And more...

Thank you for responding to me 

My requirement is if external user A sends email to multiple recipients in my organisation 

Then that email should be routed to quarantine or i should be asked to moderate that email.

In short we want to be more cautious when multiple users are marked in email , from external sender to avoid spam and its larger impact

The HeaderMatches allows for limited wildcarding, so creating a rule to match something like To: .*,\s?.* won't work.
