I have a client whom we've migrated to MS Exchange 2010. We setup two new servers, one for SQL Server 2008 R2 that runs an application our company sells which has a web site for outside HTTPS access. The client has a cheap Sonic firewall and so it's a choice of either our application or OWA for HTTPS access from outside but not both.
Is it possible to move the OWA virtual directory to the SQL Server without installing the Exchange CAS role on it? If it is possible, is it as simple as using the ECS to run the Remove-OWAVirtualDirectory and New-OWAVirtualDirectory cmdlets to first remove the existing OWA virtual directory and then add a new one on the SQL Server?
