Updated On - June 29, 2026

Summary: While using the Exchange Server, many users encounter an error, “The content index state is failed and suspended.” This can impact users trying to connect to Exchange via Outlook Web Access (OWA), who won’t be able to search their mailboxes. Thus, it’s essential to fix such errors in order to avoid any data loss. We’ve shared the methods for fixing Exchange Error Content Index State Failed and Suspended. However, if these methods don’t work, you can try Recoveryfix Exchange Server Recovery.

A healthy content index is essential for efficient mailbox searches & smooth database operations in Exchange Server. When it turns to the Failed & Suspended state, users may face search-related issues in Outlook & Outlook on the Web. On the other hand, administrators may face complications with database replications & Database Accessibility Group [DAG] functionality.

Although email delivery and mailbox access remain unaffected, it hampers overall Exchange Server performance. Ignoring the problem can lead to prolonged indexing failures & operational challenges. This guide will illustrate all the needed concerns in detail, like causes, symptoms, & useful solutions to repair failed content index in Exchange.

Content Index in Exchange Server: It is a search catalog maintained by Exchange Server that enables fast & accurate mailbox searches. In DAG, each database copy maintains its own content index. So, if it’s corrupted, Exchange may report the status as Failed or FailedAndSuspended.

Need to Fix Exchange Error Content Index? Know Causes First

Let’s look at the factors that can cause the Content Index State is failed and Suspended error:

Low storage availability.
Antivirus interference & Exchange update failures.
Disk failures, storage latency, or file system corruption.
Power failures, abrupt reboots, or system crashes.
Corrupted content index catalog. [Most Common Reason]
Replication interruptions can cause content index synchronization failures.

How to check Content Index Status?

You can use the Exchange PowerShell cmdlet in the Exchange Management Shell (EMS) to determine the issue. Open EMS and run the below cmdlet to check the content index state:

Get-MailboxDatabase Database Name | Get-MailboxDatabaseCopyStatus |
Select Name,*index*

Review the output carefully. Databases showing Failed, FailedAndSuspended, or crawling may require further investigation.

Technical Solutions to Repair Failed Content Index In Exchange

There are two cases in which you can use the PowerShell cmdlets to fix the content index failed error.

Scenario 1: When the Exchange Database is not part of the DAG

There is no passive or healthy secondary copy from which you can extract data if you run a standalone Exchange Server. In this case, you need to rebuild the index catalog. Here are the steps:

Step 1. Stop Exchange services like Exchange Search & the Exchange Search Host Controller. Run the following command:

Stop-Service MSExchangeFastSearch
Stop-Service HostControllerService

Step 2. Run the command “Get-MailboxDatabase | select EdbFilePath” to get the file path of the database. Then delete, remove, or rename it accordingly.

Step 3. Once you are done, start the service using the below PowerShell cmdlet:

Start-Service MSExchangeFastSearch
Start-Service HostControllerService

Step 4. The re-crawling & indexing process will start. It can take time to complete, which depends on the size & number of items in the database. Run the following command to see the status to find out whether the command was successful in fixing Exchange error content index state failed and suspended.

Get-MailboxDatabase Database Name | Get-MailboxDatabaseCopyStatus | Select Name,*index*

If it displays a healthy state, the error has been fixed and you can search the mailboxes in Exchange Server.

Scenario 2: When the Exchange Database is part of the DAG

This method is only applicable when the database copy belongs to a high-availability DAG network. With the help of reseeding the catalog directly from a healthy member, you can fix the index issue. Without taking the database offline, this process extract clean index copy over the network. Run the command:

Update-MailboxDatabaseCopy \-CatalogOnly -BeginSeed

It can take time because it depends on the connection between the servers & size of the database. Once the process is completed, check the status of the Content Index State by re-running the command “Get-MailboxDatabaseCopyStatus”

Other Useful Methods:

Verify disk space & system health with the Windows diagnostic tools & Exchange health checks.
Review event viewer logs [Application, System, Exchange Search, FAST Search] to identify service failures, corruption & storage issues.

When to Consider the Advanced Recovery?
If the corrupt EDB file is the main cause behind the content index is failed and suspended error, the manual methods might not help in giving successful results.
In that case, you can go with our Recoveryfix Exchange Server Recovery software to restore single or multiple mailboxes from database files without altering their items.
