The Outlook 2010 web app's conversation threading "feature" is really bugging me.

Is there any way to make it cease and desist (if so, how)?

Yes there is, you need to:

  • Click the drop down arrow next to Arrange
  • Uncheck the box next to Conversation

If you are looking to do this globally across all users I think this is only available in SP1 via OWA Group Policies

    Thanks! I never thought to look under "arrange"! I thought that was just for basic sorting. I'd been hunting around in all the options and preferences screens I could find! Commented Feb 1, 2011 at 17:59

    Thanks guys, that was helpful. Just a note: you need to go to each individual folder (inbox, sent, drafts, etc) and uncheck the "conversation" option under "Arrange by".

Actually, you need to click on the arrow next to "Arrange by:" and the current sort (e.g. "Arrange by: Date v" or "Arrange by: From v" where "v" is my lazy symbol for the down-pointing filled triangle).

Sorry if this is obvious to everyone other than me - but new interfaces do sometimes take time to get used to.

BTW if you're happy with conversation threading, wait until you get emails from a few different threads without any subject line and see what happens!


I couldn't find Arrange or Arrange By, but I did go under View when looking at my inbox (next to the New | Delete | Move | Filter) and unmarked the Use conversations option. You do need to select other folders to do the same thing (i.e. Sent items, drafts, etc.).
