Storage limits in Outlook.com

Storage space for your Outlook.com email increases monthly. Email attachments can eat up a lot of storage space so if the amount of storage you use takes up most or all of what's available, you might not be able to send or receive any messages. Additionally, people who send you email will get an error message that your inbox is full. Here's how to make a little room until your storage quota grows.

  • Empty your junk folder by right-clicking Junk > Empty folder

  • Sweep unwanted email from your inbox or archive folders. See Organize your Inbox for more information.

  • Save space-hungry photos and documents in OneDrive instead of email. Here's how:

  1. In the folder where you store your photos and docs, click Arrange by > Size.

    Note: If the message list sorts the smallest messages on top, click Arrange by > Size again to put the largest messages on top.

    Arrange by menu with Size highlighted

  2. Open the email containing the attachments your want to back up to OneDrive.

  3. Under the attachment, , select Save to OneDrive.

    Email with attachment. Download and Save to OneDrive links highlighted
