Exchange Server is an advanced but complicated software that uses several indexes to fetch items quickly. Though the Exchange Server is boosted with several advanced facilities and features, it also has some errors, and Exchange Users often face these errors. The content index state failed in Exchange Server  is a common error, and there could be several reasons behind it. However, the Exchange Information Store is the root cause of this error.

In this blog, we will explore all the dimensions of this error, including its reasons and resolution. Follow the blog till the end to get rid of the Content Index State Failed Error in Exchange Server .

What Does the “Content Index State Failed” Error Indicate?

  • Getting Content Index State Failed or suspended Error indicates that there is some issue with the Information Store or in fetching the details.
  • Database Availability Group (DAG) also needs to be cross-checked. There is a chance that the Exchange Server is not a member of DAG.
  • Antiviruses and other software that are not compatible with the Exchange Server can also cause this error.
  • Low disk space or storage shortage may also cause the Content Index State to fail in the Exchange Server.

So, we must do workarounds for the above-mentioned simple compatibility issues. Also, you must restart the server and check if the problem is resolved. If not, then read the below-mentioned methods to resolve the content index failed error by following below steps according to your Exchange environment.

Methods to Resolve Content Index Failed or Suspended Error

The methods to fix the Content Index Failed error vary depending on the root cause as well as Exchange Server settings and version. Here, I will mention all the possible scenarios ( Exchange with and without Database Availability Group) and their workarounds.

Condition 1: With DAG for Exchange Server Version 2019, 2016 and 2013

If your Exchange Environment is in the Database Availability Group, then you need to reseed the database. Moreover, finding content indexes manually and repairing them selectively using cmdlet is also a task that needs to be done.

  • Run this PowerShell cmdlet to update the mailbox database copy and repair:

C:\>Update-MailboxDatabaseCopy DB4\EX2016SRV2 -CatalogOnly -BeginSeed

  • To check the status:

C:\>Get-MailboxDatabaseCopyStatus * | sort name | select name, status, contentindexstate

Exchange Content Index Status

Note: This task is time-consuming and takes a lot of time, depending on the connection and database size.
Once this task is completed, you must rerun the PowerShell cmdlet to get back your mailbox data status.

Condition 2: If the Exchange Server is Single ( Not a Part of DAG)

It includes deleting and rebuilding the Exchange Server Indexes. But, before moving ahead, it must be in your knowledge that it is a very system memory and CPU resource-consuming task. Follow the below steps to execute this:

  • Firstly, you have to stop the services of Microsoft Exchange Search and Microsoft Exchange Search Host Controller. For this, simply click Windows + R and write ‘services. msc’.

Exchange Controller

  • Next, browse the Exchange Database (EDB) location using the file explorer.
  • Now, delete the folder with GUID containing index files.

Exchange Index Content Error

  • Restart the Search and Host Controller services that were stopped in the first step.
  • Run the PowerShell cmdlet to check the status: C:\>Get-MailboxDatabaseCopyStatus * | sort name | select name, status, contentindexstate

Condition 3: If You Are Still Using Exchange 2010

Though Microsoft has ended support for Exchange 2010, and there have been no updates since the announcement, some users are still using Exchange 2010. If you are also one of those and facing a Content Index State Failed Error, then follow the below-given steps:

  1. In this process, we will reseed the failed index catalog and retrieve the passive database.
  2.  Run EMS as admin.
  3. Now, you have to stop copying b/w active and passive databases. Run cmdlet: Suspend-MailboxDatabaseCopy
  4. Reseed the catalogue and check the status: C:\>Get-MailboxDatabaseCopyStatus or follow any other way to check the status of the content index failed error resolved or not.

What if None of the Above Explained Method Works?
