If you don’t want Outlook 2013 to create a new compressed OST file across the workstations in your environment when you upgrade your users’ Outlook client, use the Outlook Group Policy template (.A big change is that when running in Cached Exchange Mode, Outlook 2013 will only cache 12 months’ worth of data from the Exchange server by default!When you upgrade from a previous Outlook version with an Exchange mailbox to Outlook 2003 Cached Exchange mode is disabled by default.This makes it really hard to determine and control remotely whether your clients have Cached Exchange Mode enabled.
This allows you to enable/disable it with a simple logon script to create a standard in your organization without the need of forcing the recreation of the entire profile at start-up or visit each client.
Some of these are around Outlook data files (OSTs).
By default, when Outlook 2013 is installed, a new compressed version of the OST is created.
Because of this, UC Email Services recommends you disable cached exchange mode.
Outlook 2013 introduced many improvements into the most famous e-mail client.
