Manual Approach to Exchange Server 2013 Repair
Corrupt Exchange server can be repaired by using eseutil and New-MailboxRepairRequest cmdlet. Both the utilities come built in with Exchange Server.
Eseutil Utility to Fix Exchange Server Corruption
Eseutil is a command line repair tool that is capable of repairing EDB, ESE, STM, and LOG files. Tasks like integrity checking, database repairing, and defragmentation can be executed through this utility. eseutil should be used in offline mode so users must unmount the exchange store before initiating the repair process. There are multiple eseutil commands available for various purposes. However, only a few are necessary to repair a damaged Exchange database. Now we will discuss the commands that will come handy for users who want to fix damaged database of MS Exchange.
- ESEUTIL /p: This command stands for repair, which is our main purpose of this utility. It can fix database pages that are damaged and corrupt. However, it does not manage the logical relationship between tables situated in Server database. Users have to additionally use ISInteg utility to coordinate the relationships.
- ESEUTIL /r: To fix log files related corruptions, this command is used frequently. This command restores a database by replaying or forwarding transaction log files.
- ESEUTIL /g: The aim of using this command is to verify the database integrity. It is useful to check if there are any corruption issues in the database. Using this command, users can easily know whether the store had been unmounted or shut down properly or not. This command can verify the logical integrity of page level or ESE level of Exchange database. However, it cannot check the integrity of Information Store level.
- ESEUTIL /d: Once the repairing is done, this particular command can be used to defragment the database files. Any whitespace that may have emerged during repairing will get removed during defragmentation. Ultimately, it will reduce the total physical size of Exchange database by terminating indexes and blank pages. This command should not be used often.
New-MailboxRepairRequest PowerShell Command to Fix Database Corruption in MS Exchange Server
Apart from using eseutil utility, users can take the help of PowerShell command called New-MailboxRepairRequest to resolve corruption issues. Users need to have permission to run this command. It will help users by performing these tasks:
- Finds corruption in search folder (SearchFolder) Command: NewMailboxRepairRequest -Mailbox email@example.com -CorruptionType FolderView
- Calculate the number of folders that are not showing exact values (AggregateCounts)
- Views folders that are not providing accurate contents (FolderView)
- Fixes the problem when provisioned folders are wrongly pointing into unprovisioned parent folders (ProvisionedFolder)
