Change Exchange Online recipient limit
Need to change Exchange online Recipient Limits. The default value is 500 and can't be modified.
In this case, users are able to send bulk\Spam messages by selecting entire global address list.

We are working on customizable limits, but we have no ETA at this time. Thank you for the feedback.

This is now on the Microsoft 365 Roadmap, due in Q1 2020. https://www.microsoft.com/en-us/microsoft-365/roadmap?SilentAuth=1&rtc=1&filters=&searchterms=55025

A minha organização tem um sistema híbrido e com a migração para Office 365 está a tornar-se complicado gerir o processo sem que haja a possibilidade de poder alterar estes limites de destinatários para alguns utilizadores:
- Na maior parte dos casos, porque queremos reduzir o número para limitar a possibilidade de spam para um elevado número de destinatários;
- Noutros casos de excepção pretendemos aumentar, uma vez que o Office 365 em modo híbrido considera as lista de distribuição que contenham utilizadores internos, como "fora da organização" e uma vez que a organização tem cerca de 1500 funcionários, é impossível que alguém envie uma notificação, por exemplo dos recursos humanos, para todos os funcionários.
Assim, pretendia-se abrir excepções através da configuração deste limite.Agradeço que sejam breves a permitir esta configuração.

In a enterprise environment this is a essential feature.

We need to limit this to be consummate with the small size of our organization and the need to limit users from sending to lists that should be managed by our bulk mail process. It is more about user behavior, but compromised accounts etc. are also a concern. Hopefully this is implemented soon.

A tendência é aumentar mais e mais envio de email, devido os documentos digital (nfe, cte, cupom fiscal...).
Já migramos nossos emails, que era servidor local, para office365 online com o objetivo do serviço está 24x7 ativo.
Com essa limitação de envio de email em massa, está cada vez mais complicado porque temos que ficar configurando serviço de email intermediário para envio de email em massa.
Sugestão é que a Microsoft disponibilizasse ao administrador do portal do office365 online alguma opção de configuração, para incluir determinada conta de email que poderá usar o serviço de envio de email em massa ou algum limite de envio de email para determinada conta. -

Need to limit external recipients for most of our workers as they have access to PII / HIPAA data and they can too easily export a customer list and email everyone on the list in one email. We have had close calls where people were CC'ed instead of BCC'ed. Need a mechanism to stop this.

This is often an ask regarding possible data protection issues, e.g. too many external recipients in to or CC may be seen as a privacy issue, depending on the contents.
It would be great to be able to have an option in mail flow rules perhaps instead of setting limits on tenant level? -

The recipient limit control is necessary for organizations to set the number as needed. Every organization has their custom requirements which we are used to in the On-Prem environment. Missing out these controls post Office 365 migration is not acceptable.
Hope Microsoft does the needful soon

500 a minute? Great googly moogly! We need to be able to reduce this drastically down to like 10!

We are using Exchange Online Plan 1 and want to limit the number of recipients to 25. However, the option is available for 500 users and doesn't get change. Please provide some solution to the same.

Would like to be able to restrict the number of emails to restrict bulk email.

We have the same desire as many other firms; a 20-30 recipient limit would be great for us. Not for cyber sec directly but more for bulk list access control purposes.

We would also like to reduce this limit from 500 down to 20-30 for certain user populations.

We have continuing problems with staff sending bulk emails with all recipient addresses v. Providing administrators with the option to limit the number of recipients would at least contain the problem to manageable proportions.

We would like to change the default limit of 500 to 30 for our organization.
