Falls das nicht hilft:

To fix this we have to go through a few steps.

Stop the Microsoft Exchange Search and Microsoft Exchange Search Host Controller services.

Navigate to the following directory:

C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data\Nodes\Fsis 

Delete all the files in the Fsis folder (make a backup just-in-case).

Open up the Exchange Management Shell (Elevated):

Navigate to directory C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Installer

Run the following command. It will re-create the folders we deleted:

.\installconfig.ps1 -action I -datafolder "c:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data" 

After this command has completed, start the search service. You can force AD Replication or wait for it. After that it should report in event viewer that indexing has started successfully.

If the above didn't work then you will need to uninstall the search component and then re-install it. First stop the services again.


.\installconfig.ps1 -action U -datafolder "c:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data" 


.\installconfig.ps1 -action I -datafolder "c:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\HostController\Data" 

Start the services again and then monitor the event log for indexing has started and completed successfully. You can also check by running a Get-MailboxDatabaseCopyStatus in the EMS to view the content index state.
