FAQs: Microsoft Office 365 SMTP Settings

I Want to Send Bulk Emails with Office 365 SMTP. Is It Possible?

Yes, but with caveats. Microsoft imposes a cap on daily emails to avoid abuse with Office 365 SMTP. The typical daily limit hovers around 10,000 emails per account. For frequent, high-volume email senders, think about using a dedicated email marketing service.
