Office 365 (Classic Outlook on the web) - Inbox rules

This topic shows you how to use Inbox Rules to automatically perform specific actions on messages as they arrive, based on criteria you select. For example, you can create a rule to automatically move all mail sent to a group you're a member of to a specific folder. When you setup a rule in Outlook Web App, the rule will be applied regardless of the client you are using.

Note: This article only applies to the classic version of outlook on the web. For the new version of outlook on the web refer to document Office 365 (New Outlook on the Web) Inbox Rules

To manage rules, click Settings icon in the top right, settings icon > Your app settings > Mail. Then in the left-hand column Mail > Automatic Processing> Inbox Rules.

Note: The Outlook on the web client recently received an update to their options menu which is reflected in the document below. The old options menu encounters an error attempting to create a rule in Chrome when using the 'it was sent to' or 'it was received from' conditions in the rule.

How do I create a new rule?

Note: Please note that rules are NOT case sensitive. For example, if you create a rule that sends an email containing the string of characters 'to' to junk, this will send any email with the string 'TO,' 'To,' 'tO,' and 'to' to the junk folder.

To create a new blank rule using the Inbox Rules tab, choose new new.

The new rule window has three sections:



When the message arrives and:

Use this box to select criteria for your rule. Use the down arrow to view and select the criteria you want to use.

If the criteria have additional options, enter them in the window that appears.

Do the following:

Use this box to select the action you want taken when a message arrives that meets the criteria you selected.

More Options

Use More Options to:

  • Add additional conditions or actions to a rule.

  • Add exceptions to a rule by selecting Add Exception.

  • Turn on or turn off the option to stop processing more rules. By default, the option to stop processing more rules is turned on. With this option on, when a message comes in that meets the criteria for more than one rule, only the first rule will be applied. Without this setting, all rules that the message meets the criteria for are applied.

    For example, without Stop processing more rules selected, if you have a rule to move all messages sent to a public group to a particular folder and another rule to move anything from your manager to another folder, and your manager then sends a message to that group, you'll find a copy of the message in both folders. If you want only the rule that moves messages from your manager to be applied, put that rule higher in the list than the rule that moves messages sent to the group, and then edit the first rule to add the option to stop processing more rules.

  • Create a custom name for a rule.

What else do I need to know?

  • When you create a new rule in Outlook on the web, you may receive a warning that some rules that were created in Outlook and are currently disabled will be deleted. Before you delete those rules, you may want to sign in to your account using Outlook and check the rules to see if you want to keep them. Enable any rules you want to keep.
  • Rules are run from top to bottom in the order in which they appear in the Rules window. To change the order of rules, click the rule you want to move, and then click the move up up or Move down down arrow to move the rule to the position you want in the list.
  • Some types of messages won't trigger Inbox rules, including:
    • Delivery status notifications, which include non-delivery reports and system messages.
    • Read receipts and delivery receipts that are generated by an e-mail client.
    • Some automatic-reply (Out of Office) messages.
  • Each rule you create will take up space in a hidden section of your mailbox. This section is limited to 64 KB. The actual amount of space a rule uses depends on several factors, such as how long the name is and how many conditions you've applied. When you reach the 64 KB limit, you'll be warned that you can't create any more rules. If that happens, you'll have to delete or simplify some of your existing rules before you can create more. Some ways you can reduce the space used by rules are:
    • Delete rules you no longer need.
    • Shorten the names of your rules.
    • Combine one or more rules that do the same thing.
    • Remove criteria from rules.
  • When you create a forwarding rule, you can add more than one address to forward to. The number of addresses you can forward to may be limited, depending on the settings for your account. If you add more addresses than are allowed, your forwarding rule won't work. If you create a forwarding rule with more than one address, test it to be sure it works.
