If your inbox is full, you will not be able to send or receive any new messages. To free up space in your inbox, try emptying your Junk Email folder by right-clicking on Junk Email> Click Empty Folder.

You have added too many recipients to one email

Outlook.com limits the number of recipients you can include in an email message. If you exceed the limit, the error message will tell you how many recipients you can add to your email. Remove some recipients, and then try sending again.

Your content triggered junk email filters

Outlook.com will block messages from being sent if the content looks like junk e-mail to Outlook.com's junk e-mail filters. Occasionally, legitimate email can also be marked as junk email. If your message was blocked, try changing the content of the message and then sending it again.

Insufficient permissions

Information Rights Management (IRM) enables senders to specify access permissions to their email messages, including preventing messages from being forwarded, read, printed, or copied by unauthorized people. For more information on this feature, see Introduction to IRM for Email.

The message or attachments are too large

You can then try to send the message again.
