Resolving “Access to Source Database Failed With Jet Error” in Exchange Server

Microsoft Exchange Server

Microsoft Exchange Server is a reliable and advanced solution to create a collaborative and messaging environment.

It stores all the user mailboxes in the Microsoft Exchange database (EDB file), which can be accessed using the Microsoft Outlook Email client.

You should regularly backup EDB files to prevent data loss situations if the database is damaged. However, under some circumstances, the Exchange Database Server cannot be accessed after restoring from a backup.

The database restores properly, but you encounter errors while trying to access it. This behaviour leads to critical data loss and needs Exchange Server Recovery to be sorted out.

For instance, you may come across any of the following behaviours after restoring the Exchange Server database from a current backup:

1. You manage to restore the EDB file, but it is single. There is no catalogue data or transaction log file.

2. The Eseutil /p utility runs successfully on the corrupt database, but it cannot be accessed.

3. You cannot check the state of your Exchange Server database using Eseutil /mh utility.

4. You get the following errors while checking the state of the restored database:

a) Initiating FILE DUMP mode…

Error: Access to source database ‘c:mailbox database.edb’ failed with Jet error -1022.

b) Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after 0.203 seconds.

When this behaviour occurs, the Exchange Server database becomes unusable and inaccessible. You encounter the same behaviour every time you try to open the database. To gain access to your valuable data, you need to figure out the root of this issue and perform Microsoft Exchange recovery by fixing it.

Cause

This behaviour occurs due to missing log files or corrupt backup files. Exchange Server cannot access the source database in both cases, and you face this issue.

Resolution

You can try resolving this problem using the Eseutil /p command-line tool or restoring the database from backup. If possible, move unaffected files from the problem database to the new database.

If the above method does not work, you need to repair and restore the corrupt Exchange Server database using advanced and powerful third-party applications known as Exchange recovery software.

The Exchange Recovery tool is competent enough to scan the whole database and extract all inaccessible data systematically. They come equipped with a rich and interactive user interface to offer easy edb recovery from corrupted or damaged Exchange Server.

Stellar Phoenix Mailbox Exchange Recovery is the most efficient solution to handle all sorts of database corruption issues effectively.

It works well with Microsoft Exchange Server 2007, 2003, 2002, and 5.5. The Exchange Mailbox Recovery software successfully restores all EDB file objects, such as emails, notes, contacts, tasks, journals, attachments, and appointments.
