Understanding Microsoft 365 Email and Storage Services

OneDrive for Business is strictly for cloud storage, while SMTP services require an Exchange Online license.

OneDrive for Business is designed exclusively for cloud storage, file sharing, and document collaboration. It does not include email hosting or SMTP (Simple Mail Transfer Protocol) capabilities.

To utilize SMTP services for sending out emails, you need a dedicated email hosting platform. Microsoft provides this through Exchange Online, which is bundled with eligible Microsoft 365 and Office 365 Business or Enterprise plans.

1
Check your Microsoft 365 plan

Log in to the Microsoft 365 admin center and navigate to 'Billing' > 'Your products' to see if your active subscription includes Exchange Online.

2
Set up Exchange Online (if included)

If your plan includes Exchange Online, you can configure your SMTP settings in your email client using the standard server address (smtp.office365.com), Port 587, and TLS encryption.

3
Upgrade your license (if needed)

If you currently have a OneDrive for Business standalone plan (Plan 1 or Plan 2), you will need to upgrade to a comprehensive plan like Microsoft 365 Business Basic, Standard, or Enterprise to gain SMTP functionality.

SMTP Configuration Requirement: Even with an active Exchange Online license, SMTP AUTH must be explicitly enabled in the Microsoft 365 admin center for specific mailboxes or the entire tenant before you can send emails via SMTP.
