Security – How to disable Outlook security warning when opening attachments sent by internal Exchange/organization users

I had a similar problem once when a user had been moved to a different Exchange cluster, but Outlook had cached the previous reference and kept trying to send to the previous cluster, even when I specifically selected the user from the Global Address list.

The way I fixed it was in Outlook, start typing the user's name until it auto-suggests the username, use the arrow key to select the name in the auto-suggest list and hit Delete. Try typing the name again and it shouldn't auto-detect it, so you can then select the user from the GAL.

First, DON'T capitulate. He is not only an idiot but DANGEROUSLY wrong. In fact, releasing this information would violate the PCI standard (which is what I'm assuming the audit is for since it's a payment processor) along with every other standard out there and just plain common sense. It would also expose your company to all sorts of liabilities.

The next thing I would do is send an email to your boss saying he needs to get corporate counsel involved to determine the legal exposure the company would be facing by proceeding with this action.

This last bit is up to you, but I would contact VISA with this information and get his PCI auditor status pulled.
