Automatically mark old unread emails as read in Outlook
I don’t ever remember going back to read an old unread email in Outlook, months later. If the email interested me, I read it when I received it, not after 2 months. On the other hand, we all have such emails in our mailboxes: they aren’t spam, they aren’t necessarily marketing emails but also they aren’t important enough for us to read them. In this article we will detail how to automatically mark old unread emails as read, in Outlook.
Let’s say you have an unread email that’s older than 60 days. Will you ever read it? I doubt it.
It can be frustrating to keep seeing unread emails in your Inbox, but on the other hand if you mark ALL your emails as read you will likely mark as read recent emails that were supposed to be actually read in the near future. So you may do more harm than good. The solution is to mark as read only those unread emails older than a given period of time, like older than 1 or 2 months. Such emails are unlikely to be ever read.
How to mark older emails as read with Outlook
You can achieve this result using the Outlook Advanced Search options.
In Outlook 2013, go to the Outlook Search Tools -> Advanced Find -> Advanced -> Define more criteria -> select Date/Time fields, then select the “Received” field to be “on or before” a certain date. To be honest, it’s not a straight forward solution and you would have to redo & update the search criteria each time when you want to mark as read older emails, date by date.
