Hello All,


Looking at a full hard drive issue I noticed that the outlook folder was extremely large (108GB+), when I opened it I noticed the pst files and the normal outlook files, but there are 18 files that look like the following;


     NAME                            DATE MODIFIED                        SIZE

SBSE___.7LD                       11/15/2013                            9,091,449 KB

SBSE___.7P7                        5/25/2013                             3,138,953 KB

SBSE___.9QC                       3/28/2013                             8,147,313 KB

SBSE___.38C                        6/14/2013                             8,488,809 KB

SBSE___.43C                        7/8/2013                               3,359,921 KB





This goes on for 18 different files, when I googled the extensions, they say they are unknown file extensions.  This account uses IMAP, are these something to do with the folders he created in outlook?  Do you think I am safe to delete them?


Also, we use a program called SyncbackSE to backup all of the files, and they are bringing over everything but these 18 files, they will not transfer, almost like it doesn't even know they are there, and these are not hidden files.


Any ideas what they are and if I can delete them?
