When searching through OWA 2010, you may get the error “The action couldn’t be completed. Please try again.“.

You may also notice that the Application Event Viewer shows the error “Function CISearch::EcGetRowsetAndAccessor detected that content indexing was disabled for database ‘MailboxStoreName’ because of error '0x80041820' from MSSearch.“. Also you may notice the the Microsoft.Exchange.Search.ExSearch.exe task is using a considerate amount of CPU.

This may be due to an issue with SP1, and it’s advisable to upgrade to at least SP2, but if you still are experiencing this issue with SP2 or SP3, to fix it please follow the below instructions.

– Open the folder in command prompt to the extracted folder
