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.
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″ />
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.
Thanks for reading!
Matt
