Errors sending or receiving email

Outlook.com

Outlook.com won’t let me send an email

To help fight spammers and reduce the amount of junk email that you get, Outlook.com puts limits on the volume and type of email that can be sent. Here are the most common errors that you might see and what you can do to fix the problem.

Increase your limits by verifying your account

Increase your limits by going to the Add a phone web page and entering a phone number. We’ll send you a verification code that you can enter on the page. This helps us to verify that you’re the owner of the account and not a spammer. Verified accounts enjoy higher limits on email volume and content.

Tips for verifying your account

If you request that the code be sent to you in a text message, it’s the numbers in the body of the message, not the numbers in the header.

Text message with code.

If your phone can’t receive text messages, you can request that the code be delivered via an automated phone call. Be ready to write the code down.

You might be reluctant to give us your phone number. We understand – we’re all deluged with marketing these days. We’ll just say this: Microsoft never sells your security information or uses it for marketing or any other purpose. Full stop. We respect your privacy.

  • Because of network delays, it might take a few minutes to receive your code. If you haven’t received it after 15 minutes, request another one.

  • Double-check that your phone can receive text messages. Text message delivery isn’t available in all countries or regions, or from all providers.

  • To help foil spammers, we ask you to enter some letters and numbers that are in a picture.

Daily message limit

To help deter spammers, we limit the number of email messages an Outlook.com account can send in one day.

On your phone

The daily limit is lower for emails sent from your mobile device via EAS or POP. To send an email that you’ve written on your mobile device:

  1. Save the message as a draft so you don’t lose it. To save it on a Windows Phone, tap the Delete icon – you’ll be asked if you want to Save or delete message. Tap Save.

  2. Sign in to Outlook.com on your PC, open the draft and click Send.

On your PC

If you hit your daily limit for emails sent via the web, try the following:

  1. Click Save draft to save the message.

  2. If you haven’t already done so, increase your daily message limit by going to the Add a phone web page and verifying your account.

Too many recipients for one email

We also limit the number of recipients that you can have on any one email. If you receive an error, try this:

  1. The error message will tell you how many recipients you can send a message to. Remove some recipients from your email so that you’re under the limit, then try sending it again.

  2. If you haven’t already done so, increase your daily message limit by going to the Add a phone web page and verifying your account.

Content in your message triggered our junk filters

We block messages from being sent when the contents look like junk email to Outlook.com junk filters. Occasionally, legitimate email can be blocked as junk. If your message is blocked, try the following:

  1. Change the content of your message to make it look less suspect, then try sending it again.

  2. If you haven’t already, increase your daily message limit by going to the Add a phone web page and verifying your account.
