Do you see lot of connections with "E" as AO being used for connections? If yes, you may want to disable and enable EPM accelerator. This will clear up any remainders and will save connections for you.
no accelerator epm enable
accelerator epm enable
To help you further, we will need show stat connection and show version output from the WAE.
I'm seeing tons of connections like this on our core . I don't want to display the entire show stat conn output on here as we are using public IP addresses on the LAN. I did turn off EPM from the CM and re applied it, still shows up with N/A on only TCP port 135.

Device Id: 00:1a:64:ca:17:9c System was restarted on Sun Jul 18 05:57:22 2010. The system has been up for 8 weeks, 5 days, 19 hours, 55 minutes, 18 seconds.
MAPI AO is shutdown and disabled. Is there any reason why it is like that? Can you turn on MAPI and then reset EPM again to see if you come across this issue?
This is because EPM is tied up and depends heavily on MAPI. The EPM application accelerator must be enabled for the MAPI application accelerator to operate. EPM is enabled by default. Additionally, the system must define an application policy of type EPM, specify the MAPI UUID, and have an Accelerate setting of MAPI. This policy, MAPI for the Email-and-Messaging application, is defined by default.
EPM traffic, such as MAPI, does not normally use a predefined port. If your Outlook administrator has configured Outlook in a nonstandard way to use a static port, you must create a new basic application policy that accelerates MAPI traffic with a classifier that matches the static port that was configured for Outlook.
Please try enabling MAPI and see how it goes, if you can.
I probably don't really need it but If I'm hitting a policy that is using it by default, it should work by design. There are other default WAAS policies that are not related to Microsoft Exchange using EPM; such as MS-SQL-RPC, MS-AD-Replication & MS-FRS.
