Is there an option for "Mark All Emails as Read Across All Folders" in Outlook?

I have lots of Outlook folders (30+) and they each get a trickle of over 200 emails a day.

Usually I scan through each folder to make sure nothing important is in there and right click on the folder and press E to 'Mark All as Read'.

This gets tedious and I want to eliminate the second step so I can just scan through my folders then press a button to mark all subfolders and folders as read at the end.

I would like to say this differs from this as I would like to know which emails are new and not have them automatically all be marked as read when they come in.

Solution 1:

The Search Folder tip does the work. To do this go "Folder" tab > press "New Search Folder" > on the pop window select "Unread mail" > Press OK. This will create a folder, like all your others, on the left menu (where you have Inbox, Sent Items so on), named Search Folder > Unread Mail and you can right click and "Mark all as read".

Solution 2:

No there isn't a single button that does this, not in the Outlook client.

You could use a search query and then select all (Ctrl - A), right-click, and then mark all as read.
