Microsoft Exchange Server Calendaring agent is the tool that allows performing several scheduling tasks, which include creating and saving appointments etc. For the tool to function properly, it is required that Exchange directory structure remains excluded from antivirus scanning. Another disadvantage of scanning your Exchange Server directory structure is that it may also lead to corruption of the most important files in your Information Store, such as.edb,.stm,.chk, and.log files. Since most of your important data resides in your.edb files, EDB Recovery [http://www.edb-recovery.com/edbrecovery.php] becomes essential while such instances.
To illustrate such scenarios with Calendaring agent, suppose you try to save few appointments in MS Exchange Server. Your observe that Calendaring agent fails to function properly. Some or all of the calendar information are lost. Additionally, you receive the similar entries logging in application event log of Exchange Server:
Event ID: 8206
Source: EXCDO
Description: Calendaring agent failed with error code 0x80040229 while saving appointment
and
Event ID: 1160
Source: MsExchangeIS
Description: Database resource failure error First Storage Group\Mailbox Store (MAIL) occurred in function JTAB_BASE::EcPrepareUpdate while accessing the database "0xfffffc0d".
You may also encounter Event IDs: 2 and 7200 describing the failure of Exchange Calendaring agent.
Cause
Exchange Server exhibits the above described behavior when a file-level antivirus software is installed and is configured to scan the Exchange Server directory (EXCHSRVR) structure.
Solution
The solution to this problem is to reconfigure your antivirus software and not to include EXCHSRVR directory and drive 'M' in this scan.
A file-level antivirus software locks and scans the file that is currently being tried to access by Exchange Server. Thus, the Information Store fails to lock this file and eventually, the file may become corrupt and unusable. When this occurs, your first recommendation is to restore the database from a previous backup or apply eseutil repair utilities (/p and/or /r switches) for the affected database(s).
However, if none of the database restore method works, you need to use an EDB Recovery Software that can scan and repair the corrupted database effectively. The EDB Recovery utilities are exclusively designed and simple products that allow to repair and restore the damaged Exchange database.
The EDB Recovery Tool is an excellent working utility that repairs corrupted Exchange Server database and restores the individual mailboxes as *.pst files. The advanced EDB Recovery Software supports Exchange Server 5.5, 2003, and 2003. The tool provides an easy and safe mailbox restoration with an interactive user interface.
