Microsoft releases Service Pack 1 for Office Filter Pack 2010
Yesterday’s announcement that Microsoft had released Service Pack 1 (SP1) for the Office Filter Pack 2010 provoked some thoughts about the importance of this component to Exchange 2010. In fact, the Office Filter Pack is a prerequisite for both mailbox and transport server roles and you cannot install these roles on a server if you haven’t first installed the Office Filter Pack.
According to Microsoft’s blog entry, the “ updated filter pack doesn’t have any fixes or updates that impact Exchange scenarios or functionality ”, a somewhat curious state of affairs as you’d assume that a service pack contains something of interest. The conclusion that I have is that the fixes and updates incorporated into this service pack are of interest to other products – or something like that. Some of the backchat from Exchange engineers about the update indicates that Exchange customers don’t have to rush to get the update. They can simply wait for Office Filter Pack 2010 SP1 to appear through Windows Update and then apply it.
Exchange first started to use the Office Filter Pack in Exchange 2007 when they introduced content indexing as part of the mailbox server role. As items are added to a mailbox database, Exchange indexes the content into a set of catalog files maintained for the database. Users who work in online mode can use the indexes to perform searches. Usually these are OWA users as Outlook users typically work in cached Exchange mode and use local indexes for searches, only resorting to content indexes when they need to find something in an archive mailbox. Interestingly, the Mailbox Replication Service (MRS) in Exchange 2010 updates the content index for the target database as it moves content from source to target mailbox to ensure that the content index is fully up-to-date when MRS eventually switches the Active Directory pointers to allow a user to access their moved mailbox.
Exchange 2010 introduced discovery search functionality as part of its initiative to help organizations control information better. Discovery searches depend on content indexes and can only find information if the content indexes are updated and fully populated. If the content of an item cannot be understood by Exchange its content will not be fully indexed and might therefore be undiscoverable by a search.
Apart from searches, Exchange uses content filters on transport servers to allow the transport engine to examine content in messages as they pass through its pipeline. Transport rules that need to block messages that contain certain words or phrases make heavy use of the filters to locate suspect messages.
Getting rid of Cached Exchange mode issue | OST to PST Conversion
A majority of organizations across the globe rely on MS Exchange Server for their routine working schedules. Exchange Server enables its users to work offline so that they don’t have to compromise on anything, even network connection.
Cached Exchange Mode is a feature of Exchange Server, which enables you to work with MS Outlook in offline mode. During the Cached Exchange Mode, a local copy of the user’s Exchange mailbox is created on the computer’s hard disk. This local copy is called Offline Storage Table (OST) file. The OST file enables you to work offline with MS Outlook in the same way as you work with Outlook when connected with Exchange Server.
The work you do in offline mode will get automatically synchronized with your mailbox on Exchange Server when you logon to your Outlook account. But, sometimes when synchronization fails then working in Cached Exchange mode may also lead into the loss of the work that you have done offline. Synchronization can be failed due to following reasons:
* Mailbox has been infected from a virus.
* Mailbox has been damaged due to the damage of Exchange Server.
* Mailbox has been deleted from the Exchange Server.
Whatever be the reason for the failed synchronization, you are left with nothing but data loss because the OST file becomes inaccessible. In that scenario, you need to convert ost to pst in order to access the email messages with MS Outlook.
Kernel for OST is an advanced, reliable, and cost-effective software, which helps you convert ost to pst without any limitation of file size. You can quickly convert a large ost to pst in just few moments. The software supports all versions of MS Exchange Server starting from Exchange Server 5.0 to Exchange Server 2007.
