How to Fix the Exchange 501 Jet_errLogFileCorrupt Error?

Just like any other mailing server, Microsoft Exchange can also suffer from all kinds of transactional or logical errors. For instance, if you are not able to mount the database or if there is an issue with its log files, then you can get the Exchange Server Error 501 on your system. Thankfully, you can easily fix Exchange 501 jet_errLogFileCorrupt error by following some smart approaches that I have listed in this guide.

Fix Exchange Server Error 501

Part 1: Things to Know about the Exchange Server Error 501

As you know, the Exchange Server is comprised of two major entities – a JET database and a transactional log. Now, if there is a problem while mounting or initializing the database, then you can encounter the Jet Error 501.

Apart from that, if there is an issue with the transactional log in the system, then it can cause inconsistency in the database. To avoid redundancy, Exchange displays the Server Error 501 that stops us from accessing our data.

Part 2: Common Causes for Getting the Exchange Server Error 501

Ideally, if you have also encountered the Exchange Server Error 501, then it could be caused due to the following reasons.

Dirty Shutdown

If the Exchange server has been turned off or restarted abruptly, then it can enter into a “Dirty Shutdown” state.

Corrupt Log

The transactional log files of your Exchange database could be missing, corrupted, or are not able to be processed by the system.

Mounting Errors

Another possible reason for getting the Exchange Server 501 error could be related to issues with the mounting or initializing of the database.

Other Reasons

Apart from that, the Jet Error 501 can also take place due to a malware attack, a corrupt EDB file, a missing header, bad sectors, or any other technical issue.

Part 3: How to fix Exchange 501 jet_errLogFileCorrupt Error Easily?

When I wanted to fix Exchange 501 jet_errLogFileCorrupt error, I came across a few solutions – some of them worked while others didn’t. To help you, I have listed all the working solutions in two main categories.

Approach I: Manual Solutions To Fix Exchange Server Error 501

If there is a minor issue with your Exchange database, then the following manual approaches will help you overcome this issue.

Solution 1: Restore a Backup Copy of the Database

The simplest way to fix the Exchange Server Error 501 is by restoring a previous backup and mounting the database again. To do this, you can go to the native Backup & Restore feature of Exchange or use any third-party application.

Restore Exchange Backup

As the restoring wizard would be launched, you can choose to extract your backup from a preferred source (online or offline). Once the restoring process is completed, you can go to your admin account of the Exchange server and mount the database again.

Solution 2: Remove Corrupt Log Files or Restore Log Data

One of the major reasons for getting Exchange Server Error 501 could be related to your corrupt or unavailable log files. To fix this, I would recommend manually getting rid of any corrupt log data. If you want, you can later restore your log files from an existing backup too.

Whenever you want to fix Exchange 501 jet_errLogFileCorrupt error, just go to the Start menu, and look for “Services”. As the Microsoft Services window is launched, you have to look for the Exchange Diagnostics service and launch it.

Microsoft Services Exchange Diagnostics

Now, you can just choose to browse the Diagnostics location of the Exchange server. From here, you can find dedicated folders for all kinds of performance, daily, and transactional log files.

Locate Exchange Log Files

Afterward, you can just select any log file of the Exchange server (that you think is corrupted) and get rid of it. You can also manually copy any existing version of the log file and replace it with the new one from here.

Solution 3: Use the Exchange Utility Command

To help us manually fix all kinds of issues with our Exchange server, Microsoft has come up with a dedicated command – ESEUTIL (Exchange Server Database Utility). Using it, you can resolve any logical issue with your Exchange database and can even perform a soft or hard repair.

Therefore, to fix Exchange 501 jet_errLogFileCorrupt error, you can just launch the Command Prompt and enter the “Eseutil.exe” command. Once the utility prompt is loaded, you can run the following command:

eseutil /ml <name of the log file that is damaged>

Repair Exchange Log Files

This will automatically check the respective log file of your Exchange database and will resolve any issue with it.

In case, if that won’t work, then you can fix the Exchange Server Error 501 by performing a soft or hard repair of the database by entering these commands:

Soft Repair: Eseutil /r /d “<path to your database file>”

Hard Repair: Eseutil /p “<path to your database file>”
