Cannot Mount Exchange Mailbox Store with Events 9175 and 455 - Computers - Software

Exchange Server mailbox store is composed of user mailboxes and system mailboxes. Each mailbox store is made of two files : Priv.edb and Priv.stm. When a disaster occurs to any mailbox store, the EDB file is considered to be the most vital component of recovery, for the reason that it contains all email messages, headers and text attachments of users' email messages. There are various Exchange Repair software available that can repair a corrupted Exchange database, in case when you don't have any valid database backup to restore.

For instance, consider a scenario when you try to mount your Exchange Server mailbox store. The mount operation might fail logging the events 9175 and 455 in application event log.

Cause

There can several possible reasons that can cause the described issue:

1.An antivirus software is running that has deleted the Exchange log files

2.You have performed soft recovery for database using eseutil /r with incorrect logfile base name

3.Mailbox store is corrupted

Solution

To solve this issue, you need to try these fixes:

1.You should ensure that antivirus software doesn't scan Exchange Server directories. It can even corrupt the database files. If the log files have been deleted, you should restore the database from backup and play through the log files. In case when no good backup is available, you need to run Exchange repair utilities for bringing the database to consistent state.

2.You need to perform soft recovery using correct log file base name, such as e00, e01, e02 or e03.

3.If the entire mailbox store is corrupted, you should run Eseutil /r to repair it or restore from backup. However, you can also run Eseutil /p as hard recovery operation, but this causes the dirty pages to delete. So, it is recommended to use commercial Exchange Server Repair tools that can safely repair a corrupted Exchange database.
