Our exchange server is going to be soon upgraded from 2003 to 2010.
When we upgrade to 2010 are these applications going to break and will they need re-writing to use EWS ?
I have done some initial research and I know that WebDev is being depreciated and no longer supported by Microsoft.
What I don't know is if WebDav is just not supported, or if it has been completed removed from the newer versions of Exchange.
Can someone shed some light on this please?
