Using Classic Outlook on Windows for personal email, calendar, and contact management
I had the same issue and while I wait for the official fix, I use this AutoHotKey (AHK) script to map the first CTRL+SHIFT+{1..4} --> CTRL+SHIFT+{6..9} Place this file (NewOutlookKeyMapping.ahk) in your startup directory, then change the bindings in Outlook that were {1..4} --> {6..9},
For exemple, you will still hit CTRL+SHIFT+1 but Outlook will receive CTRL+SHIFT+6
