Tenant Customizable Recipient Limits
In Exchange Online a mailbox user is allowed to send to a maximum of 500 recipients per message. This default value currently can’t be changed by the tenant admin. Yet, many admins would like to raise this limit on at least a few mailboxes (for monthly newsletters for example). Others want to significantly lower it (to, say, 50 or some such) for most or all mailboxes in their organization, as part of a perceived defense-in-depth strategy to reduce the potential impact should a hacker compromise a user account and start blasting out spam, or a disgruntled employee tries to air their grievances company-wide. With the upcoming customizable recipient limits, you’ll now be able to customize this setting between 1 and 1000, for a single mailbox, multiple mailboxes, and for the default setting for new mailboxes that you create in the future. Single and bulk edit will be available in the Exchange Admin Center UI, while customizing the default setting for new mailboxes can be done via Remote PowerShell.

Must be getting developed in production...
Just adding in my gripe that the planned allowed values of 1 through 1000 - seems off the wall to me. Why not allow 0, especially when you're allowing twice the current maximum for the upper limit? It's just inconsistent and I hope that you will allow 0 in the end. 0 works fine when it's allowed.
Well it went live, and still I am confused on the reasoning for the minimum setting of 1 instead of 0. It feels like a tease, having this feature finally enabled, only to just miss my personal reason for its need in the first place.
