Error "There are more results available than are currently displayed" after May 2022 installation

[VincentBurle83]

I recently installed May 2022 security update on my Exchange 2016 CU22 DAG.

I restored the customization on web.config of ECP  to display all OU from ECP (https://docs.microsoft.com/en-us/exchange/troubleshoot/administration/exchange-server-not-display-al...) , but it does not work at all neither after a recycle bin nor an IISreset on the server.

When I check the PoSh command executed it is still "Get-OrganizationalUnit -IncludeContainers:$true -ResultSize 500" whereas it should be with 1500 according to the change I made in the web.config file.

Did someone have the same issue?

Thanks for your help

I finally solved the problem by editing the file "C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\ecp\web.config" as well with the same setting:
I added the line "<add key="GetListDefaultResultSize" value="1500"/>" just above </appSettings>
