I was asked the other day if there was a way to expand all the Outlook Inbox folders without clicking each one separately. The person had inadvertently moved a folder somewhere else, and they wanted to be able to see all the expanded folders so they could easily spot it. My first pass at research made it appear there was no way to do that without writing macros and such, but then I found this tip that works pretty good (provided you’re running Windows)…
In the example below, I have a folder (Renewal Tracking) that has a number of nested subfolders in it:
In order to expand that folder without clicking on it, I can left-click the Inbox folder and then press the Windows Key at the same time you press the Asterisk key on the numeric keypad on your keyboard:
(This is the Windows Key)
As you can see, the Renewal Tracking folder has expanded one level. If I had other first level folders, they would have expanded also. If I keep pressing that key combination, everything continues to expand as deep as necessary:
If you want to collapse everything again, just double left-click the Inbox folder.
I have noticed that sometimes a single Windows > Asterisk combination key press will expand everything in one press. I’m not quite sure why that is, but either way this is far better than having to click each item individually.
