We have Exchange 2003 as our email server for work. I work for a digital imaging company so we do receive alot of attachments. This one particular guy receives alot more then anyone else. Lately he has been having problems where someone will attach a file (.pdf or .zip) and when he goes to open it, it is corrupt. Sometimes they will send 4 or 5 files and some will be good and others will be corrupt. I know it's something on our side because he receives files from 100's of different customers and it happens from everyone with no apparent pattern. It's not the file size because some of the corupt files are bigger then other files attached and some are smaller. I've had him forward the emails to 3 or 4 other people within the company to see if they could open the files and they are corrupt for them too, which makes me think it has something to do with exchange 2003? He can receive anywhere from 100-500MB of attachments a day...any suggestions?
