Summary: Exchange log files note down each action happening in Exchange Server environment and any corruption or deletion in these log file can damage the database too. In this article, we will check some clean methods to recover Exchange data without requiring log files and how a professional Recoveryfix for Exchange Server tool can repair the corrupt databases.

Exchange database stores a great number of user mailboxes which contain emails, contacts, calendar events, attachments, etc. Transaction log files play an essential role in the Exchange database. All the changes made to the databases are written in transaction log file first, and then it is written to the Exchange database. However, in some conditions, log files get damaged or deleted leading to Exchange data losses. Some common reasons behind corrupted Exchange log files are sudden termination of system (interrupted power supply), inconsistent database (dirty shutdown state), virus contamination, etc.

Recommended Solution
Use the Recoveryfix Exchange Server Recovery software to avoid the lengthy and bulky process of manual data recovery. It allows you to recover any corrupted or inaccessible Exchange EDB files.

Ways to recover Exchange data without log files

There are two ways to retrieve the corrupted or lost log files in the Exchange database:

  • Soft Recovery
  • Hard Recovery
Soft Recovery

Soft recovery process automatically reads the checkpoint points when administrators try to remount a database. However, if it is not automatically mounted, you can perform software recovery using the Eseutil utility. Run the below-mentioned command in Eseutil:

ESEUTIL /r enn /L [path to log files] /s[path to checkpoint file] /d[path to database file] /i
Norms of replay in transaction log files

There are some norms for replaying in transaction Log files which cause restriction:

  • Checkpoints point to a wrong Log file.
  • Database files from the storage group are removed.
  • The path of the log file is changed.
  • Log files are in different database.
Hard Recovery

In hard recovery process, you need to restore the backup ,which generates a file in the temporary folder with the name restore.env. Now, you must replay log files in restore.env against the Exchange database as below:

C:\Program Files\ Exchsrvr \bin>eseutil/ cc “C:\Temp\First Storage Group”

Here, you can see that C:\Program Files\ Exchsrvr \bin is the location of Eseutil and C:\Temp\First Storage Group is the location of the restore.env file. It shows the valid backup of database files.
If log files are damaged or missing, then it is impossible to recover the data. When your log files are damaged or missing, Exchange will display some errors like JET-Error -501 (0xfffffe0b), JET-Error -515 (0xfffffdfd), JET-Error -514 (0xfffffdfe), or JET-Error -533 (0xfffffdeb). Now, you need to apply the mentioned Eseutil command to repair the files.

C:\Program Files\Exchsrvr\Bin>eseutil/p “D:\Exchsrvr\Maiboxdatabase.edb”

Both soft and hard recovery may result in errors and some work only if log files are available. It may be difficult to recover data of lost files using these methods.
