Re: Help! Trouble restoring after file system corruption removed files on drive with Exchange databases

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi Kevin,

Thanks for your reply.

If the log files are missing, the eseutil /cc command may fail, but the
effect is littler.

Yes, the transaction log works with both Public Folder and Mailbox Store.

Hope this helps.

If you need further assistance, please don't hesitate to let me know.

Best regards,

Robert Li(MSFT)

<Thank you for your reply. I have a few follow up questions:
<
<If the .env file specified that there are 3 logs in the sequence that
needed
<to be played in, and one of those was corrupt and had to be deleted as
<identified by the eseutil /ml test, how would the eseutil /cc then succeed
<with that log file missing? Wouldn't it fail because of the missing log?
<
<The transaction log files contain transactions for both the public and

<
<Thanks.
