Introducing Exchange Online Tenant Outbound Email Limits

That’s interesting and VERY sad news. I had a client that hit their limit and could no longer send emails. With the rolling 24hr calculation they were not going to be able to send emails again for about 13hrs. We stood up a ProofPoint Essentials environment quickly for them and configured the Outbound Relay and they were able to start sending again even though their usage was showing over the limit in the report.  What is Microsoft's solution to enable additional sending?  Adding licenses does not scale well as the more users you purchase the less each license gets you.  The HVE has limitations that are not realistic for general business email.  Using Azure Communication Services does not look to be a solution as that looks to be handling more traditional bulk emailing, not daily business communications.  Just to put this in scale for a SMB customer that has about 370 users, their limit is about 41,000 which means each user gets on average about 111 emails per day or less than 14 per hour for an average 8 hour day which is WAY different than the previously (and still default) sending limits of 10,000 emails per HOUR as listed https://learn.microsoft.com/en-us/office365/servicedescriptions/exchange-online-service-description/exchange-online-limits#sending-limits-1.  I understand there may be a need to limit the outbound emails, but I do not understand why in cases where the volume is exceeded we cannot utilize a 3rd party service.
