FAQs About Fixing an Outlook.com Send Limit for a Contact List

What is the maximum number of recipients I can email at once using an Outlook.com contact list?

Outlook.com typically limits free accounts to sending emails to a maximum of 100 recipients per day, and up to 300 for Microsoft 365 subscribers. If your contact list exceeds these limits, you will receive a send error.

How do I send a message if my contact list exceeds the daily sending limits?

You must split your large contact list into smaller groups that fall under your account's daily limit, or spread the mailings out over multiple days to avoid triggering the spam filter restrictions.

Will increasing my account reputation instantly remove the send limit restriction?

No, while verifying your account with a mobile phone number builds reputation and can increase your sending limits over time, it does not instantly bypass the maximum recipient threshold for a single email.

Does upgrading to a paid Microsoft 365 subscription permanently eliminate all recipient limits?

Upgrading provides a higher daily sending threshold and allows emailing more recipients per message, but it does not remove limits entirely. Strict caps remain in place to prevent spam and abuse on the platform.
