In this blog, we explain about MS Exchange Server and their errors and know, how to fix Exchange Pub1.edb file error.
Microsoft Exchange Server is a very effective and powerful email server that put together Exchange Storage Engine (ESE) and security information stored to provide smooth email communication. While dealing with the intrinsic Exchange Server database, you can notice that information stored has .stm and .edb files. In addition, Exchange Server considers the default mailbox database as Priv1.stm and Priv1.edb files.
On the other side, Pub1.stm and Pub1.edb files store all the emails related to default public store. When it comes to the .edb file entity, the ESE database keeps MAPI messages and necessary email attachments.
Pub1.edb damaged by Jet Engine Error or Exchange Dirty Shutdown State
Exchange admins are used to going through several events where Exchange Server cannot perform a normal shutdown. Here are some of the reasons –
- Unexpected system failure due to lack of power backup
- Constant errors on hard drive sectors
- Dirty system shutdown on the email restoration process
There are different reasons behind the inefficient shutdown. You also have to understand the intricacies involved at the most profound level of the Exchange database. When any of the given reasons occur, the Exchange Server database cannot isolate itself from streams of transaction logs, which impacts the integrity and consistency of the database. If you restart the services of Exchange Server, the server seeks missing log files at this instance. If it goes missing, it creates the situation of Exchange server corruption.
Let’s check out the other serious possibility, i.e. jet engine errors and their effect on the Exchange database. Exchange Jet Engine errors occur due to software or hardware crashes, affecting the Exchange database at various levels.
Some Common Errors Resulting from Jet Engine Error:-
- Jet Database engine
- Exchange Server information storage
- Exchange Server file system
The security of both Private and Public EDB mailboxes is compromised in the above cases. At the lowest level of the Exchange database, corruption also brings adverse effects as we go deeper into Exchange information storage. Along with it, you cannot deny the risk of Pub1.edb file corruption. It needs intelligent and proactive troubleshooting to recover all email files.
How to fix Pub1.edb File after Severe Crashes?
When fixing Pub1.edb files, you need to recover the whole Exchange information storage with a command-line prompt. You can easily interact with detailed functionalities of Exchange Storage Engine with disaster recovery commands.
Steps to fix Exchange Pub1.edb file error
Scrutinize the Exchange Server error and act well.
Stop Exchange information store process and go to bin folder with the command interface.
Input command “eseutil /mh ..\mdbdata\priv1.edb” at command line “C:\exchsrvr\bin>.” Now press Enter.
Check the State of Exchange database and figure out if it is clean or not.
If you have any problem, perform soft recovery when you export the folder to the location of log files.
Hit the command “C:\Program Files\exchsrvr\BIN\eseutil” /r E00” at the path C:\Program Files\exchsrvr\MDBDATA>.
If nothing happens after applying the above command, it’s time to perform hard recovery.
At the command line “C:\Program Files\exchsrvr\MDBDATA>” enter the command – C:\Program Files\exchsrvr\BIN\eseutil” /p pub1.edb.
Discard .chk and Temp.edb files with log files on MDBDATA folder.
Mount and dismount Exchange Server Database and stop Exchange information store process.
Defragment Public EDB mailboxes with this command – C:\Program Files\exchsrvr\BIN>eseutil /d “C:\Program Files\exchsrvr\MDBDATA\pub1.edb”
Fix the Isinteg.exe with this command – C:\Program Files\exchsrvr\BIN>isinteg -s (servername) -fix -test alltests.
Close command prompt and restart Exchange Server to start recovery of Pub1.edb corrupt files.
When the Exchange database is affected by jet engine errors and the most critical dirty system shutdown, you won’t have to be worried if you cannot recover essential email items even after conducting a smooth and complex recovery process. In such cases, you need to download the reliable and professional Exchange Server Recovery tool to fix all .edb files, including Private and Public files.
