“FSLogix gives us true Cached Exchange Mode through its Office 365 Container. Our Outlook launch times went from several minutes to seconds. We also saw a dramatic improvement in the ongoing performance issues when navigating within Outlook such as opening a new email and composing an email, replying to an email, and switching to the calendar. FSLogix removed the roadblock that Cherry Health had reached with its Office 365 migration.”

  Cherry Health Removes Microsoft Office 365 Performance Roadblock With FSLogix


802010 Outlook Search

For enterprise class performance expected by your end-user community, Cached Exchange Mode (CEM) must be enabled in Outlook.  Once CEM is enabled, very large files (.OSTs) will need to persist between virtual workspace sessions.  Doing this with traditional approaches like roaming profiles or Folder Redirection will lead to extensive logon times and severe network and performance issues, often times preventing the success of virtual desktop initiatives.  To make matters worse, many of these workarounds are supported by Microsoft in a very limited scenario and on a ‘best effort basis’.

FSLogix addressed this problem with the release of our award winning Profile Container solution, launched at Citrix Synergy 2015.

Starting in July, 2016, a subset of FSLogix Profile Containers is now sold as a separate drop-in module, FSLogix™ Office 365 Container, allowing administrators to take full advantage of our Office 365 support without having remove their existing profile or UEM solution. This new offering is the industry’s first drop-in solution that enables true Cached Exchange Mode for all virtual workspaces using Office 365, real time search for virtual desktops, and allows user data to persist/roam in OneDrive or OneDrive for Business.
