Part 1: What is an Exchange Jet Error 1216?


You might already know that Exchange stores all its data in the form of EDB files (private or public). Now, while mounting, dismounting, or accessing these EDB files, there can be all kinds of issues. These errors can corrupt an EDB file or tamper with its B-tree structure.

Now when you know the common reasons for getting the Exchange Error 1216 JET_err: Attached Database Mismatch, let’s learn how to resolve this. Ideally, I would recommend following these methods to learn how to fix Exchange Error 1216.

Solution 1: Check the Consistency of your Exchange Database

The first thing that you should do is perform a consistency check on your Exchange database. For instance, if the Exchange Jet error occurred due to a dirty shutdown, then you can perform this solution.

To do this, you first have to launch Command Prompt on your system as an administrator and just enter the “ESEUTIL.exe” command to load the Exchange Server Database Utility. Afterward, you can enter the following commands:

eseutil /mhdatabase_file_name| find /i “consistent”

eseutil /mh database_name | find /i “Shutdown”

Exchange Utility Check Status

These commands will help you check if the database has encountered a dirty shutdown so that you can resolve the issue subsequently.

Solution 2: Perform a Soft or Hard Repair of your EDB Files

After checking the consistency of your Exchange server, you can know its present status or whether it has undergone a dirty shutdown.

If there is an issue with your EDB files, then you need to perform a soft or a hard repair of your Exchange server. To learn how to fix Exchange Jet error 1216, you need to load the Command Prompt and enter the “ESEUTIL.exe” command first.

Now, you can just enter the “Eseutil/r” command to perform a soft repair of the server followed by the exact address of the EDB file. If it doesn’t work, then you can enter the “Eseutil/p” command instead to do a hard repair.
