One particular email in Outlook inbox is red


What would cause one particular email in my Outlook (2010) inbox list to turn red?

Like everyone (I assume), I get a plethora of new emails in my inbox every day and have another plethora of them stacking up faster than I can ever seem to get to them. However, I don't think I remember one of them changing to red.

It's from a known recipient with whom I correspond frequently. I've opened it and read some of it but have not yet sent a reply. Also, I can't remember if it was red from the outset but I don't think it was.

I've got my inbox columns configured to display in the following order:

       Icon — Attachment — From — Subject — Received — Category…

and the info in each column is in a red font — but only for that email.

Is it something the sender did or is it something I did inadvertently?

Hi Steve,
Since you're likely not color coding it on your end (via a Conditional Formatting rule), it's probably happening because the sender (in this one particular case) set the follow-up flag to a date/time in the past — either accidentally, or intentionally so that it would show up in red (hopefully, not the latter, as this is not a nice thing to do on purpose). Regards, Joe

By default, only overdue emails are red. These ones that have flag with due date set.

Hmm…I don't even know how to do that (ie set a due date) so it must have come that way from that sender.

Many thanks for the responses.
