Basically there’s a problem with the catalog data for the database, we need to recreate it. WARNING this can use a fair bit of CPU power to recreate, so you might want to do it at the end of the day.

1. On the Exchange server that’s hosting the database that’s giving you the error. Start > In the search/run box type services.msc {enter} > Locate the Microsoft Exchange Search Indexer Service and stop it.

Exchange Search Index

2. Navigate to the folder that holds the problem Database (Look In Exchange System Manager > Organizational Configuration > Mailbox > Database Management > Right click the problem Database > Properties). Within the folder you will find another folder called CatalogData-xxxxxxxxxxxxxxxxxx > Delete this folder.

CatalogData Folder

3. Then restart the Microsoft Exchange Search Indexer Service.

MS Search Service

4. The catalog will now rebuild.
