Exchange 2019 Override Search limit over 250 limits

We have numerous lawyers with large mail boxes reaching 100GB, they insist on saving everything in their mailboxes.

using cache mode is limited to 50GB by default and raising it will just eventually max out there computer hard drive.

using the command New-SettingOverride -Name "Increase Search Results Limit" seems a good option.

I have seen a couple of threads to over ride search limit in exchange 2013:

and exchange 2016:

Does anyone have any experience with this command in an exchange 2019 environment:

    Hi @J Lyons ,

    Based on my test in Exchange 2019 CU12, the command mentioned in the two forum posts can still do the trick.

    I run the command below on the Exchange 2019 mailbox server:

    New-SettingOverride -Name “Exceed Search Limit over 250” -Component ManagedStore -Section StoreSettings -Reason “Override Search limit over 250 limits” -Parameters @("MaxHitsForFullTextIndexSearches=1000")  

    Then untick the checkbox of "Improve search speed by limiting the number of results shown" in Outlook > Options > Search. After that, I am able to see more than 250 search results when running in online mode:

    You can have go on your end to make change, just do remember to inform users that they need to adjust the setting below within their Outlook applications as well:
