An Exchange server is a vast platform, which exclusively operates on the Windows server operating systems. It is the powerful technology that rapidly combines ESE (Extensible Storage Engine) and storage of the enhanced security, in order to equip a seamless communication over the network. We will cover all relevant information about Exchange Pub1.edb corruptions with possible solution.

While operating the Exchange Server database, users are going to encounter two storage files i.e., STM and EDB files. In addition to this, the server establishes a default storage mailbox, named as Priv.edb and Priv1.stm files.

On the other hand, there is two more email storage files, which are by default associated with public store and these files are named as Pub.edb and Pub1.stm.

Well, whenever one is using an EDB file entity then, it means that an ESE database is storing some crucial MAPI messages with their respective attachments.

What Reasons Prone Exchange Pub1.edb to Corruption?

An administrative user will be experiencing variety of hazardous situations, which will interrupt their working in between. Following reasons might be associated with the Exchange Pub1.edb problem:

  • A sudden power failure due to the absence of the power backup
  • Interruption of the email restoration process leads to the cause
  • Some error occurred in the sectors of hard drive

There are multiple reasons that are involved in propagation of the dirty shutdown. A person needs to learn all the complications thoroughly, which he/she might face while working with the Exchange server.

If anyone of the above-mentioned situation occurs then, the database file will become inaccessible for isolating itself from the transaction log.

In such cases, what people generally do is that they restart their services of the Exchange, which in return actually leads to more chances of corruption occurrence.

Considering the cruelest situation i.e., jet engine errors in Exchange and its impact on the server database. Such type of errors is originated due to crash in hardware or software, which may be responsible for a severe damage in Exchange at different stages. Well, if users are facing these jet engine errors then, following path may get affected:

  • Jet database engine
  • Information store on the Exchange server
  • Database file system on the Exchange server

Whether the database engine gets damaged or there is problem with the server storage, all time only one thing gets compromised i.e., Private and Public mailboxes. The mailboxes files are prone to corruption and there is high possibility of Pub1.edb file to get affected.

Therefore, it is mandatory to have proactive and smart troubleshoot solutions for handling an Exchange error i.e., Pub1.ed corruption cannot be denied.
