I'm seeing the exact same thing, using Outlook 2007/2010 against Exchange 2010
with Pound in between.

Is there some magic Alive/Client/TimeOut value set to make this work fluently?

Or is there some way to disable the Outlook tooltip warning?
The tooltip warning is more annoying than the disconnect itself, as the reconnect
is immediate.

I'm using a slightly different approach than in this example: Pound is only
proxying /rpc/rpcproxy.dll . Everything else is proxied on another server,
using Apache.

I'm using an HTTP non-SSL backend. Exchange 2010 allows this if you check
"SSL offloading" in the OAW settings.

Thanks,
Pim

We have this configure to do do rpc over https for exchange 2010.
However, every few seconds it seconds disconnected and then restored.

The config is:
