Hi @Shivaprakash S,

Welcome to the Microsoft Q&A platform!

To increase the search limit from 250 to 1000 in Exchange Server 2016, you can use the following command in the Exchange Management Shell:

New-SettingOverride -Name "Increase Search Results Limit" -Component ManagedStore -Section StoreSettings -Parameters @("MaxHitsForFullTextIndexSearches=1000") -Reason "Increases Search Result Limit from 250 to 1000"

After running this command, you need to restart the following services for the changes to take effect:

Microsoft Exchange Information Store:
Restart-Service

Microsoft Exchange Search:
Restart-Service

Microsoft Exchange Search Host Controller:
Restart-Service

These steps should help you increase the search limit and apply the necessary changes.

Hi @Shivaprakash S,

Thanks for your response!

I’m sorry to hear that! You can try another approach.

1.You can check if there is a checkbox called "Improve search speed by limiting the number of results shown" in your Outlook client > Options > Search. If so, untick it and you should be able to get more than 250 search results. 2.If your Outlook client is a newer version, the checkbox may not be available. You can try manually editing the Microsoft.Exchange.Store.Worker.exe.config file to increase the search limit. Here's how:

a.Locate the Configuration File:

-Navigate to %ExchangeInstallPath%/Bin/.

-Locate the file named Microsoft.Exchange.Store.Worker.exe.config.

b.Edit the configuration file:

-Open the file in a text editor.

-Add the following line in the <appSettings> section:

<add key="MaxHitsForFullTextIndexSearches" value="1000"/>

c.Save and close the file.

d.Restart the following services to apply the changes:

Restart-Service HostControllerService Restart-Service MSExchangeFastSearch Restart-Service MSExchangeIS

Hi @Shivaprakash S,

Thanks for your response!

Then you can try to use the following format command to increase the search results to 1000：

New-SettingOverride -Name "Increase Search Results Limit" -Component "ManagedStore" -Section "StoreSettings" -Parameters @("MaxHitsForFullTextIndexSearches=1000") -Reason "Increase search results limit"

Hi @Shivaprakash S,

Thanks for your response!

I'm very sorry for my mistake. I sent the command again because in my test environment, I tried the command again and I could get more than 250 search results in OWA.

Since this method does not work in your client, I suggest you try the following method:

Before making any configuration changes, it is recommended to back up the relevant configuration files in case of problems.

Modify the web.config file:

Connect to the computer hosting the Exchange server via Remote Desktop.

Navigate to the following path, which may be different depending on the actual installation path:

C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\owa

Find and edit the web.config file. For safety reasons, you can make a copy of the original file as a backup.

Increase the maxHits parameter:

In the web.config file, find the <appSettings> section.

Add or modify the following items:

<add key="Search.MaxResultsOnClient" value="1000"/> <add key="Search.MaxResultsOnServer" value="1000"/>

Make sure the above key-value pairs have been correctly added to the <appSettings> section.

Close and save the web.config file. Open a command prompt and run the following command as an administrator to restart IIS: shell iisreset /noforce

Log in to OWA again and search to see if you can get more search results.

In Exchange 2016, when you search for emails using OWA or EAC, only 250 items will show by default. To increase the limit, you can so this with the help of commands in EMS.

Connect to your Exchange Server using EMS.

Run the command to set the limit to 1000 for mailbox searches.

Set-OrganizationConfig -SearchResultsCap 1000

You need to restart after this. Restart the Information Store and IIS services-

Restart-Service MSExchangeIS

iisreset

Now the search limit will be increased to 1000 items.
