Outlook 2016 offline address book not updating cached mode
If the connection is restored, Microsoft Office Outlook 2007 automatically switches back to Connected or Connected (Headers).
Any changes you make while a connection to the server isn't available are synchronized automatically when a connection is available.
For example, when you use a fast connection, Office Outlook 2007 copies the header, body, and attachments of an email item from the email server to your computer.
When a slower connection is selected, only headers are automatically downloaded.
You cannot use Cached Exchange Mode with a POP or IMAP account.
Top of page Shared folders include Exchange Public Folders, Share Point folders, or another person's Exchange folders when you’re using Delegate Access.
Now you are ready to restore the backup from your restore software. Ensure you select alternate location to restore and give recovery server and recovery DB name.
Use Cached Exchange Mode to work with items in your Microsoft Exchange Server mailbox even when your network connection is slow or unavailable.
When the On Slow Connections Download Headers Only setting is selected, Outlook stops automatically downloading full items and also leaves attachments on the server.
For example, you may use a laptop computer at your office and connect via a network cable to your corporate local area network (LAN).
