Mailbox Importer uses the default web proxy unless it is overridden in the Hyland.MailboxImporter .config file. This can be done by uncommenting the block in the .config file.
<!--<system.net>
<defaultProxy>
<proxy proxyaddress="http:"//##.##.##.##:## bypassonlocal="true"/>
<bypasslist/>
</defaultProxy>-->
</system.net>-->
You can uncomment by removing the “<!--” before <system.net> and the “-->” after </defaultProxy>.
Note: In the proxy address line, ##.##.##.##.## is the
placeholder for the IP Address or URL of the proxy server .
