Dears, I need your help please to solve this issue today I download the microsoft filter pack for microsoft application in the exchange 2007 I have CCR enviornment , and I do the exact steps provided by microsot in this link http://support.microsoft.com/default.aspx?scid=kb;en-us;944516 I use the script way after finish the client who are using owa , this message appears Search results may take a long time to appear because Exchange search is unavailable. Results will not include matches in the message body any way search is working but i want to make the indexing working good then I go to rebuild the full-text index catalog from this link to solve the issue http://technet.microsoft.com/en-us/library/aa995966.aspx but it give me this messages MSExchangeSearch service stopped No Index for Database: Mailbox Database MSExchangeSearch service Started all the services is running , the mailbox database is about 500 GB , so it take time or what !! what should I do to solve this issue or as a last resort touninstallthe Microsoft filter pack , then what to do with the registery which are edited I appreciate your help Regards,

I forgot to maintain that there is no any errors or warnings in the event viewer REgards

If I stop the services , and delete the files manually then start the services it will not make any new file any suggestion

after a very long troubleshooting and deleting and many errors in the event log sometimes which drives me crazy , I unistall the pack filter , delete the registery file that is created (of course the search services wasstoopedwhendeleting) then one of the server is working very fine , but the another is give me the same thing in the client side with no erro in event log I am thinking of the update-storagegroupcopy -deletexistingfiles to update the non-stable server from the stable server , so what is your suggestions ?? Regards

the problem has been solved what I did is the following so if anyone face this later I stop the search services and uninstall the filter pack and delete theregistrythen start th services but it didn't work , so I return the registry which I delete and install the pack again then I decided to move the cluster to the another node it give me big error in themovementwhich has no description and only no. but the clustered has been moved , then replication error and the reason is : Unknown , so It drives me crazy . and many error in the application about the search the description was (msexchange search raise ....) so I didn't search for it coz I thought the system will be down and I have to work quickly , so do again what I did at the first (stop services deleteregistry,uninstall, and start services) so the error just went away and in the client OWA didn't give the error (Search results may take a long time to appear because Exchange search is unavailable. Results will not include matches in the message body) so after tow hours and everything is stable I return it back to the another node but the errors in the clients only come back again , so return again to the first node , then restart the passive node , and then move the cluster , and everything is working soooo fine sorry for the long post but i just want to help the others because when i search for error (No Index for Database: Mailbox Database) all the solutions is to reinstall the mailbox server role and with some of them it didn't work after there-installation I know what I did is not a logical solution but it works as the steps in the post ,and it was a very non-happy moments when you want to improve the search and see errors like (replication failed , move cluster failed , search failed ... ) even I did the same steps mentioned in this article http://support.microsoft.com/default.aspx?scid=kb;en-us;944516 but all this mess happened Regards
