Configuring preferences and options in Outlook.com
Hi Stranz,
That is the new 'current time' indicator (and can't be 'fixed'). If you use the week or work week view, it will extend over the earlier days in the week, but not into today.
You can leave a suggestion at uservoice - i did not find one complaining about the new design- you can post one of your own.
i found this one that wants it on today only (or bolder on today) - https://outlook.uservoice.com/forums/322590-out...
I also found one that likes the new design but wants an arrow instead of a dot and this one wants a dot on both sides of the current day.
