Encrypted emails send from Outlook or Office 365 can only be read by the recipient that has the private key, preventing others from reading the content of the mail. It also can protect your email from being forwarded. If you have Office 365 then sending encrypted mail is really easy.
I just migrated a huge amount of mail and folders from a PST file to O365. The problem is now the folders are empty in Outlook that I know I migrated over. Here is the strange thing. If I right click on the folder and look at the synchronization tab, although it appears empty it shows "Server Contains 10 items - Offline Folder contains 10 items"
