Outlook for iOS now has an 'Ignore Conversation' option

Microsoft Outlook is bringing its "Ignore Conversation" feature to both its iPhone and iPad apps, helping those who want to mute and remove irrelevant email threads from their inboxes. Desktop users of Outlook are familiar with this feature, and now if you're on iOS, you gain access to this, too. Microsoft seems to be rolling this out bit by bit, so just be patient if it hasn't made its way to you yet. Unfortunately, it doesn't seem to be available for Android users right now.
