I am new to PGP Desktop but I have a few users that have it installed. One of my users recently had it reinstalled. She is running PGP Desktop 9.8/outlook 07. Whenever she emails one specific user that previously had PGP installed years ago, it encrypts the message being sent to him. He cannot read these messages being sent because he no longer is running PGP. He is not in her list of users that she shares keys with but it still encrypts the message to him before sending. I have googled around for some assistance but have not found any answers that could help. Is there someone that could point me in the right direction? Is there somewhere else that this data is stored?
