 Cached Exchange Mode
.OST files, Exchange, Exchange monitoring and logging, Outlook
I'm new to Exchange and I have read that Microsoft Outlook opens/performs faster in non cached exchange mode rather than in cached exchange mode. Is there a reason for this? I understand the initial setup of the .ost file can take awhile if you have a large mailbox but after that, is there a difference in terms of performance?

Default is on for mailbox and off for public folder favorites. The main disadvantage of Cached mode is that changes are not propagated to the server immediately. Any user on an exchange server that have to dial-in into a network to retrieve e-mail should not use cached exchange mode, as it will run slower.

Like Rechil mentioned, cached has to go through more processing than non-cached, thus the delay in using it with Outlook…

The only advantage to cached exchange mode is for someone that wants to read their e-mail off-line. Turning off cached exchange mode shows your e-mail from the server. No downloading to an .ost file is required. I turn off cached exchange mode on local desktops and new e-mail is instantaneous.

Yup like mentioned the main advantage of cached mode is to use outlook offline, if you require users to use it offline then turn it on, if not turn off.

Microsoft Outlook 2003 and newer versions introduce a new feature called Cached Exchange Mode, which is actually an improved version of offline folders in Outlook older versions. Cached Exchange Mode provides many functions to make the synchronization and offline operations efficiently and conveniently. One of them is Exchange Recovery Mode.
you will see the following warning message when your Exchange mailbox is reset or inconsistent:
“Exchange is currently in recovery mode. You can either connect to your Exchange server using the network, work offline, or cancel this logon.”
which indicates Outlook and Exchange are currently in Exchange Recovery Mode.
