EAC doesn’t show complete list of OUs

Hi All,

Came across an quick issue where I didn’t see a lot of coverage online, so though I’d share.

A customer reported that when creating a new user in the EAC, not all OUs were displayed when specifying the OU the user should reside in.

OU - more results2

To fix this requires quick visit to the web.config file found under C:Program FilesMicrosoftExchange ServerV15ClientAccessecp (assuming Exchange is installed in the default location). The below text then needs to be added in to the web.config file in the appSettings section.

<!–allows the OU picker during placing a new mailbox in its designated Organizational Unit to retrieve all OUs – default value is 500 –>

<add key=”GetListDefaultResultSize” value=”1000″ />

OU - webconfig

Change the value to correspond to the amount of OUs in your environment (my customer had just under 5000). This will need to be done on all Multi Role/Mailbox servers in your Exchange organization and once complete you will now be able to see all OUs when creating a new user in the EAC.

OU - all results2

Thanks for reading!

Matt
