If for whatever reason you do not see a specific e-mail inbox for your corporate BES mail, no worries; you can still create separate inboxes on your own.

Just open up any mailbox, hit the BlackBerry Menu key, scroll down to and click Options, then click "Inbox Settings." On the Inbox Settings screen, uncheck all the listings for your Web mail accounts. In other words, you want to uncheck any and all mail accounts that are not your BES mail, so only corporate mail appears in the Messages folder. You should also uncheck "SMS and MMS" beneath the "Other Message Types" heading, so the main Messages inbox collects only your BES mail. By doing so, you're making the default Messages folder your new BES-specific inbox.

Depending on your specific app-settings, some non-BES messages may still appear in the Messages inbox, like chats. But you can modify settings within those apps to remove chats/notifications/etc. from your now-BES-specific Messages folder, as well.

Voila. You should now have separate e-mail inboxes for your BIS and BES accounts.
