Outlook for Mac - Keyboard shortcut to categorise an email?

I've just moved from windows where I could assign a keyboard shortcut to my categories (Ctrl+2, etc).

I'm trying to create a custom keyboard shortcut for this via

System preferences -> keyboard -> shortcuts -> app shortcuts.

However I can't seem to access the dropdown options of categories.
I can set a shortcut for "Categorise" but this does nothing.
I want to create a shortcut for

Categorise -> "My Category here"

Would really appreciate any advice you could provide!

Categories I have
Shortcuts I've tried

Solution 1:

I literally just had the same dilemma and had to figure it out myself after not finding a decent answer. Try entering the full menu path separated by -> e.g.:

Messages->Categorise->Action Required

Note that your menu structure may differ slightly to mine depending on your system locale and version of Outlook. I am from Australia and we use the -ise instead of -ize spelling (recognise instead recognize).

Solution 2:

See also this answers.microsoft.com answer. You can add a keyboard shortcut under Shortcuts -> App Shortcuts ; select Microsoft Office.app. Simply use the category name as the Menu Title: in the keyboard shortcut. You don't need the menu path.
