I Cannot Read Encrypted Email in Outlook

Microsoft Outlook is a popular email program used to send and receive messages. Senders have the ability to "encrypt" an email message so that the message is more secure. However, there seems to be a common problem where the recipient cannot open the encrypted email in his or her own Outlook program. The reason is that the recipient is trying to open the email in "cached exchange mode," which does not allow encrypted emails. This problem happens in Outlook 2003.

Step

Open the Outlook program. Go to "Tools" and "E-mail Accounts."

Step

Click "View or change existing e-mail accounts" and "Next."

Step

Click the name of the account you want to change and click "Change."

Step

Clear the box next to "Use Cached Exchange Mode" and click "Next."

Step

Click "OK" and "Finish."

Step

Close Outlook and then reopen it. Open the encrypted email message.
