outlook 2016, search result limitation adjustment

key location

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Search

add DWORD (32-bit) Value :

• Value name : SearchResultsCap
• value data : [num], in decimal

limitation value adjustment

• current cap in outlook : 250
• suggested : 500

notes on "removing" the limitation

setting a value of 0, ideally, will remove such limit in search results, but out initial findings suggest that it has a cap at the value of 1050, could possibly be owing to a hardcoded limit by outlook, or the local index cache being incomplete;
