You have the ability to keep unwanted conversations or emails out of your Inbox by using the Ignore feature in Outlook. Ignoring a conversation automatically removes the message from your Inbox and puts it into your Deleted Items folder.
A Conversation is a thread of email responses with the same Subject. Ignoring conversations in Outlook will also remove the replies/responses by others that may be on the email thread.
There are currently two versions of Office 365 Outlook available. You can determine which web version of Outlook you are using by looking at the toggle button in the upper right corner. The toggle button will either say:
Option 1: Try the New Outlook or,
Option 2: The New Outlook.
Directions for both instances are available below. Please be sure to check which version you are using prior to determine which directions you should view.
