Exchange Public EDB files

Exchange Server as we all know supports EDB file format to store its data and this EDB file further contains priv1.edb file and pub1.edb file. Now with every EDB file created, STM file generates automatically. So when we talk about public EDB files, they are pub1.edb and pub1.stm files. These public files store all the emails which are associated with public folder. As EDB files are very crucial for your Exchange Server and are also susceptible towards any kind of corruption, dirty shutdown of your Server creates problems in EDB files. This dirty shutdown of Exchange Server could be because of any reason like:

  • Power failure without any power backup.
  • Bade Sector Areas problem in Hard disk.
  • Improper shutdown of Exchange Server while it was sending or receiving emails.

Apart from dirty shutdown, malware or virus attack could also cause corruptions in your crucial pub1.edb and pub1.stm files. Once any kind of corruption or damage happens to your EDB files you will be bombarded with various Jet Engine errors. Some of them can be like "JET_errRecordNotFound", "JET_errDatabaseCorruptedNoRepair", "JET_errRecordDeleted" etc.
