Outlook Web App Light

The light version of Outlook Web App is optimized to work with browsers that don’t support the standard version of Outlook Web App. If possible, we recommend using a supported browser so that you can use the full feature set available in Outlook Web App.

The light version can be used to read and send mail, manage your calendar, manage contacts, and to set a variety of options. This article answers common questions you might have as you get started.

How do I get back to Office 365?

When using the light version of Outlook Web App, the navigation to the rest of Office 365 is not available. For example, if you’re using Office 365, you can’t get to your SharePoint sites.

To get back to Office 365, you can either use the back button in your browser, or go to https://portal.microsoftonline.com, and sign in again.

What’s different between the light and standard versions of Outlook Web App?

The light version of Outlook Web App has fewer features than the standard version: see the comparison tables for details.

Some features are server-based, and can be set up in the standard version of Outlook Web App or in Outlook, and then can be used in the light version. For example:

  • Inbox rules are stored on the server that hosts your mailbox and will work no matter what client you’re using to access your account.
  • Email forwarding.
  • Creating contact groups. In the light version, you can use groups that you created in Outlook Web App or Outlook, but can’t modify them.
  • Creating task and notes. You can read tasks and notes that you created in Outlook Web App or Outlook.
  • Connecting or disconnecting other email accounts.

Some features are specific to the email client. For example, the light version of Outlook Web App doesn’t provide the following:

  • Built-in spell check. If your browser contains a spell checker, you can use it.
  • Weekly or monthly calendar views.
  • Access to shared mailboxes or shared calendars.
  • Importing or exporting messages or contacts.
  • Create or modify tasks or notes.

Are there any other options if my browser isn’t supported?

If the light version of Outlook Web App doesn’t meet your needs, and you can’t use a supported browser, try one of these other options for accessing your mailbox:

Troubleshooting

If email that you expect isn’t in your Inbox, here are some ideas for troubleshooting:

  • Check your junk email folder.
  • If the email is in a connected account, it is pulled into the light version of Outlook Web App once an hour.
  • Check with the sender to make sure the message was sent to the correct email address.
  • Refresh your browser by using SHIFT+F5. Messages are available as soon as they are received by the server.

What should I do if I have some other problem?

Try posting a question in the Email and calendar forum in the Office 365 community.
