To allow more than 30 messages per minute maybe up to 50?
Currently office365 has a messaging limit of 30 per minute. It would be idial to have this increased to maybe at least 50 per minute.
The referenced limits only apply to hosted mailboxes. These limits are in place to prevent abuse on multiple fronts (unlike some limits, this is not simply a matter of adding capacity, since spammers would also be able to take advantage of higher limits). For applications which need to send bulk email, it is not necessarily a current best practice to use an Office 365 hosted mailbox.
One issue with the suggestion is that while 50 may be enough for your company’s application today, it may not be enough in the future, or for someone else — how much is enough?
We will certainly periodically re-visit all limits in the service as we have consistently done, and raise those which we can raise. We are certainly considering all options including future features & offerings. However, at this time, we feel that using a bulk mailer or on-premises server for mass email is a better solution for customers with higher requirements at this time.

We just migrated a client from in-house Exchange to O365 Bus Prem., 95 licenses. Their application SW batches and sends 100 +/- invoices daily. They can group invoices and send multiples to each customer but some of their larger customers require individual invoices. There has been suggestions of going back to the exchange server but we may need to use a 3rd party SMTP server. Since the Try This Instead suggestion is over 3 years old, is there an updated suggestion?
We currently send over 150 invoices from our finance mailbox but everything gets blocked and send to quarantine because if this limitation. Then we have to call IT to spend hours remediating the issue

The idea is not to promote spam but because we have systems which generate reports to our clients. We will need to send them monthly statements of their investments and various other forms of information via email. To overcome this limitation we have to add a delay in our code.
