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