Why Exchange Server Behaves sluggish?
What changes might have caused Exchange Server to respond slowly?
This blog post is to understand and enable one of the feature which can help Microsoft Exchange Server to perform the way we expect.
Some companies might follow Online Exchange Mode for Microsoft Outlook Client. Doing so might cause Performance issue at times. Due to the Disk I/O Read/Write operation increasing abnormally which in turn causes Performance issue.

Online Mode may help some organization with small size environment, however medium to large scale enterprise has to move to Cached Exchange Mode. This not only improves clients experience, also server responds in a timely manner.
With that said lets move further by Enabling Cached Exchange Mode feature with the help of Active Directory Group Policy.
To enable Outlook Template please follow steps mentioned from 1.2 to 1.10 in my previous blog which is available here.
Doing this will prevent users in creating Online Exchange Mode.

In figure 1.1 any users can change the cached mode to online mode. No control on end users.
Now lets force group policy to disable the feature so tat nobody will be able to change this settings.

In figure 1.2 we will edit “Use Cached Exchange Mode for new and Existing Outlook Profiles”.
Figure 1.3 : Enabling the “Use Cached Exchange Mode for new and Existing Outlook Profiles”
Figure 1.4 : Command to Force Group Policy.
Run the command on Outlook machine. close and open Outlook.
