We are moving forward to exchange 2007 and Outlook 2007
Customers that are in Outlook 2007 Cache mode were receiving a lot of Conflicts and local failures in their Outlook profiles.
We made a change on the Blackberry servers to change the polling for a minute to reduce the number of conflicts. This was while we were in Outlook 2007 in MAPI mode.
They recently just enabled RPC over HTTPS and the conflicts/ local failures are back.
We do not want the customers to wait 2 or 3 minutes for messages to reach the handheld, but we have to have RPC over HTTPS enabled in the organization
