Outlook address book not updating in cached mode 2016
Now go back to C:\Program Files\Microsoft\Exchange Server\V14\Client Access\OA 10. This means that your Offline Address Book has now been updated, next we will update the clients Address Book and confirm that they have the latest one. FORCE OUTLOOK TO UPDATE THE OFFLINE ADDRESS BOOK 1. Look at the bottom of the right-hand side of Outlook application, it should say Connected to Microsoft Exchange, and an OST file is present in the computer. If Cached Exchange Mode is not enabled, then it will say Online with Microsoft Exchange.A user cannot open an inaccessible file in Outlook application.Cached Exchange Mode is one of the two modes to connect the Outlook application with an Exchange account. The cached mode has a job of keeping a local copy of the user’s exchange mailbox stored on the hard drive in the form of an OST file.While the Cached mode is enabled in Outlook, the Outlook client will check the OST file for all the information and searches, and another process will constantly update the mail and synchronize it will open the cached file.It also requires a much better connection to the server, as far as latency is concerned.
In Cached Exchange Mode, the default is to use the “Offline Global Address List” (OAB).
You should use cached mode anytime a user must access their mail without network connectivity, such as users who travel.
You should also use it for any users in an office with intermittent network connectivity, or whose network latency between client and server is typically high, like those with satellite or radio-based connectivity.
If you want to recover the content of an OST file, then you should use a professional tool like Kernel for OST to PST which can recover complete OST file data.
OST to PST converter is one such tool which can recover a severely corrupt OST file by converting it into PST format which is accessible in Outlook.
