Today thousands of companies worldwide are using, or are on the verge of adopting Microsoft Office 365, with Exchange, or email in/from the cloud being the number one use-case. This solution is often delivered through a non-persistent Workspace meaning, RDSH, like XenApp, or pooled VM’s as part of a VDI. Since a direct connection to Azure, a.k.a. Online mode doesn’t perform well, Office 365 is usually deployed in Offline mode. In the case of Exchange, this means that the .OST file is stored (cached locally) in the user’s profile, which leads to large profiles and long (er) login times.
