Hey there,

My inbox is full again. I went to archive and I get the below message after the archive is finished:

Error while archiving folder "Inbox" in store "XXX@XXX.com". The file C:\Users\XXX\AppData\Local\Microsoft\Outlook\XXX@XXX.com.ost cannot be accessed. Data error (cyclic redundancy check).

That file is in it's proper location, it's currently 6.5 gigabytes. 

Hi,

It might be that your data file (.ost) got corrupted while archiving. Please first check your hard disk for errors, then try to repair your data file by using Inbox Repair tool (scanpst.exe): http://office.microsoft.com/en-us/outlook-help/repair-outlook-data-files-pst-and-ost-HA010354964.aspx

For detailed steps, please refer to this KB article: http://support.microsoft.com/kb/319128 (It refers to .pst in the article, should also apply to .ost file).

Hope this helps and feel free to post back.

Thanks,
