I wrote an article two years ago on how to setup a printer to scan to email using Microsoft Office 365 SMTP Settings. If you missed that article, here's the link (http://www.whaddya.com/2012/10/using-office365-for-your-printer-scan.html).
To save you some time, here's how I do it using Microsoft Office 365 for my SMTP in our office.
First you need the following information:
IP Address of your Printer, Subnet Mask, Gateway and DNS servers. You need it for networking purpose, ask your Administrator for this information. If you're reading this article, you might be the Administrator :).
For example, here's my printer TCP/IP configuration.
IP Address: 192.168.2.100
Subnet Mask: 255.255.255.0
2nd your SMTP Server information:
For SMTP Settings using Microsoft Office 365.
SMTP Server Address: mail.global.frontbridge.com. I used their public (external) IP Address in the past for easy configuration but when it's down you can't print-to-scan too. So I highly recommend to use the fully qualified domain name (FQDN) e.g. mail.global.frontbridge.com to benefits the use of it's redundancy.
Port Number: 25
I assume that you added your email address to the Printer Address Book. Now scan a test page, select your email address in the Address Book, then press Scan.
Check your email mailbox of the scanned documents.
Here's the captured Email SMTP Setting:
You don't need the POP Setting for this purpose, because you are only using SMTP setting to send.
