We are having trouble will incoming and outgoing attachments becoming corrupt. The attachments show up in email Outlook or OWA and have the correct size, but are not readable. I've disabled the AV software completely hopeing that this was the cause, but the problem continues. I'd appreciate any advice on getting to the bottom of this. This system had been working fine for a couple of years before this problem showed up.
