Changing Outlook 365’s Reply Default Setting

Posted on by Jeff Feiertag

With the recent (Fall 2015) changes to Outlook 365, the Reply button defaults to Reply to All, frustrating many and generally promoting bad netiquette. Here’s how to change the default:

  • Log into Outlook 365.
  • Note the default reply option on your O365 toolbar.

    Reply Drop Down Arrow
    (Note, if you wanted to keep things as they are but just choose alternatives based on the e-mail message, simply click the drop-down arrow).

  • Find and click the Settings icon in the upper right-hand corner.

    Settings Cog 

  • Select Options.
  • Choose Reply Settings.
  • Change the default setting from Reply All to Reply instead and save.
