I currently have a single Exchange 2010 setup and many remote office connecting over VPN to it. The further away users get the slower access is. We are in CA and have an office in France, they feel the pain the most, even with cached mode it can be very slow.
Exchange is running on 2008 R2 standard, its is a VM with data center licensing on all host.
We will be adding an MPLS connection to this office this year, but I don't know if that will help performance enough.
What is the best thing to do to resolve this issue? Can I add a Mailbox server at their location, Can I sync public folders with this type of setup? They still rely on public folders heavy and Cached mode does not help currently with public folders.
Any links, search terms, or info is appreciated.
