email limits 10k o365 - multiple mailboxes with Servicenow

edgil — Tue, 14 Apr 2026 19:18:08 GMT

Hi All, we are faced with an issue that we are sending out approx 10k emails from Servicenow and hitting the O365 limit of 10k...i was under the impression that we could create multiple mailboxes for different modules

IE . Asset, Reservation, ITSM and configuration each module to use its own mailbox, but ServiceNOw states this is not possible...has anyone been faced with this?

As per ServiceNow documentation, you can only have one SMTP email account active at a time. You can add multiple POP3 or IMAP accounts for incoming.

So if this is the setup you require for some reason, you will need to update the O365 limit.

Thanks how does an organization that has thousands of emails and employees solve for this ?

I have seen them just use the ServiceNow OOB config. And I have seen implementations where they were using their own, but even with 100k emails, they never ran into these kinds of issues. But I worked for them from the ServiceNow side and don't know what their contracts said. Fact remains: if you want to keep using O365 for this, you will have to raise the limit.

Not sure if you aware but increasing o365 is not an option

are you using a relay?
