O365 Group Email Address Recipient Limit?

New Contributor

Does anyone know what the recepient limit is for an O365 group email address, specifically with dynamic membership if that matters?  Since O365 groups can have thousands of members I would assume you could email the entire group.  When I put the address into Outlook I see a warning that it will be sent to at least 1000 members, so I wanted to verify it would send it to more than that and if there is in fact a hard limit?

That's not the recipient limit, when you address a group it actually counts as a single recipient. What you're seeing is the "large audience" mail tip:
