My company is planning to upgrade from Exchange 2003 to 2010. We are
currently using Unity 7.0. We'd like to run the two in parrallel for a bit and take our time switching users over.
Now I've read that Unity can support Exchange 2010, but I haven't found anything about running Unity using both Exchange 2003 and 2010 in parrallel.
Is this something Unity can handle?
