Strange this, feels like OA should break every time implementing RPC/MAPI from Exchange iApp.
Since LTM rejects all unspecified ports natively, and Outlook Anywhere sends RPC traffic to the RPC/Mapi VIP on 6001-6004 port range.
OA will proxy traffic to DNS name specified in the Exchange RPCCLIENTACCESSSERVER property. And by recommendations the property points to the RPC/Mapi VIPs DNS name.

OA and RPC/MAPI have nothing to do with each other. OA uses HTTP, and RPC/MAPI uses RPC. For OA, you'll see traffic being sent to 443. For RPC/MAPI, you should see an initial request to 135, then requests to either the 2 static ports or a range of ephemeral ports, depending on how you have Exchange set up.
