There are more results available than are currently displayed in Exchange 2013 ECP

The Problem

When you try to view Organisational Units or public folders and you have more than 500, not all are visible and you get the message “There are more results available than are currently displayed”. This is because Microsoft have limited the results to 500 and you cannot get more results.

The Solution

On the Exchange server navigate to the Exchange install folder then \ClientAcess\ECP.

By default it is in the following location:
“C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp”

Find the web.config file, and make a copy of it,and then edit it :

Find the <appSettings> section and add the following key :

<!– Allow the OU picker for New-Mailbox to retrieve 1000 organization units from AD, default = 500 –>
<add key=”GetListDefaultResultSize” value=”1000″ />

This will increase the maximum OU’s displayed to 1000. Set the value to something suitable for your needs.

It will look like this:

Close and save the file.

Next, Navigate to the FrontEnd\HttpProxy\ecp folder.

By default it is in the following location:
C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\ecp

Again, find the web.config file, backup and make the same changes, using the same value as before and save it.

You will probably need to close the ECP and reopen it, if you have it open, but this should resolve the issue.

Unfortunately, I believe these changes need to be made again, if you upgrade Exchange with any CU update, but hopefully you’ll not see “There are more results available than are currently displayed” again.

If this helps you out please leave a comment below,
