Fix email sync issues or remove a device from your Outlook.com mailbox

Outlook.com shows the mobile devices that you use to connect to your mailbox. If you're no longer using a device or a device isn't syncing properly, you can delete it from this list. Doing so removes the partnership between the mobile device and your mailbox, but doesn't delete the email account from your phone. Removing this partnership following the steps below often fixes sync issues.

If you're using Outlook.com and your device still won't sync or you're having connection problems, see Using the Microsoft Support and Recovery Assistant for Office 365.

  1. Sign in to Outlook.com.

  2. Choose Settings Office 365 setttings button - looks like a gear next to your name next to your name in the upper-right corner of the page, then click Options.

    Click Settings > Options

  3. In the left navigation bar, under General, choose Mobile Devices.

    General > Mobile Devices

  4. Select your phone in the list, and then select Remove to delete the device partnership.

    Remove phone from Outlook Web App

  5. Select Yes in the confirmation box.

    If you only want to remove this device from the list, stop here. If you're attempting to fix a sync issue, continue with the remaining steps below.

  6. Go to your mobile device and power it off completely.

  7. Restart your mobile device after a few seconds, and then sync your mailbox again.
