How to remove or update rules from older versions of Outlook?

Question

I somehow have a rule that's filtering important messages to a weird folder, but there are no visible rules that match that folder. But there is a warning sign that says:

There are rules created with a different version of Outlook or Outlook Web Access that are not shown.

How do I delete or modify those rules?

Answer 1

Log into Outlook Web Access. Select Options then All Options (or whatever it might be called), Organize E-Mail and then Inbox Rules.

I had rules listed here, not listed in Outlook proper.

Answer 2

This can be done using the Office 365 portal.

Microsoft describes it under Inbox Rules in Outlook. Reproduced for convenience.

To manage rules:

1. In a web browser, sign in to Outlook Web App using the URL provided by the person who manages email for your organization. Enter your user name and password, and then click Sign in.

2. At the top of the page, choose Outlook (or Mail). Or, choose the app launcher [the grid icon] > Mail.

3. At the top of the page, select Settings [the gear icon] > Options.

In Options, select Organize email > Inbox rules. Or, in Options, under MAIL > Automatic processing, select Inbox rules.

And then:

If you have a rule that you no longer want, you can select it and then click delete [trash can icon] to remove it. If you just want to turn the rule off for a while, remove the check mark next to the rule.
