Outlook offers significant configuration options for handling incoming messages. In this guide, you will find instructions on blocking senders, marking senders as safe, setting up forwarding, and creating or removing inbox rules.
In addition to configuring the way your mail client filters emails, you may also follow the steps detailed in the following guide to report an email as malicious, or to report a false positive or false negative: https://www.uvm.edu/it/kb/article/proofpoint.

Removing Client-Side Rules
In classic Outlook (and other email clients), it’s possible to create rules that only take affect when the client on which they were configured is open. This typically happens if you try to create a rule that can’t be processed by Exchange, such as one that prints an email. If you try to create a rule like this, Outlook will warn you that the rule will be client-side only, and it will ask you to confirm.
Client-side rules will not carry over to a new computer, device, alternate email client, or Outlook Online, or even the new version of the Outlook desktop app. Additionally, it’s difficult to troubleshoot mailbox issues when client-side rules are enabled because IT does not have a complete view of the rules impacting your account. Thus, it’s highly recommended to use only server-side rules.
