Encrypt e-mail messages in MICROSOFT OFFICE 2010

Encrypting an e-mail message in Microsoft Outlook protects the privacy of the message by converting it from readable plain text into scrambled cipher text. Only the recipient who has the private key (private key: The secret key kept on the sender’s computer that the sender uses to digitally sign messages to recipients and to decrypt (unlock) messages from recipients. Private keys should be password protected.) that matches the public key (public key: The key a sender gives to a recipient so that the recipient can verify the sender’s signature and confirm that the message was not altered. Recipients also use the public key to encrypt (lock) e-mail messages to the sender.) used to encrypt the message can decipher the message for reading. Any recipient without the corresponding private key sees garbled text.


Sending and viewing encrypted e-mail messages requires both sender and recipient to share their digital ID (digital ID: Contains a private key that stays on the sender’s computer and a certificate (with a public key). The certificate is sent with digitally signed messages. Recipients save the certificate and use the public key to encrypt messages to the sender.), or public key certificate. This means you and the recipient each must send the other a digitally signed message, which enables you to add the other person’s certificate to your Contacts. You cannot encrypt e-mail messages without a digital ID.
If you send an encrypted message to a recipient whose e-mail setup does not support encryption, you are offered the option of sending the message in unencrypted format.
This process also encrypts any attachments sent with encrypted messages.

OUTLOOK 2007 Keeps Asking For Password

After upgrading to Exchange 2010 many OUTLOOK 2007 clients began to experience an issue where Outlook constantly prompted users for a password.

When prompted for the username it may appear as “username”. That wont work. Prefix the username with your local domain exactly as you would with Outlook Web App. Example: domain.local\username.


If the above fails you can try the microsoft hotfix below. My experience was a 50% success rate with the hotfix.

Microsoft offers a solution here



Under certain network conditions, Microsoft Office Outlook 2007 prompts you repeatedly for a password. If you do not enter a password or if you enter an incorrect password, Outlook 2007 may silently enter Offline mode. In this case, you do not receive an error message or a notification, and you will not be connected to the mailbox..

Outlook 2003, 2007 Auto Complete – Backing Up and Restoring

Do you miss the convenience of Outlook automatically completing people’s names as you begin to type them on your new computer? Are you upgrading to a new computer and don’t want to lose all the names stored in your Outlook Auto Complete feature? Wouldn’t it be nice if Outlook installed on your new computer just “remembered” the names and filled them in for you? Personally I think this information should be included in Outlooks .pst data file but what do I know. Well fear not. You never have to go through this again and I’m going to show why and how to address this. You can copy the names in Auto Complete from your old computer to your new one. Our example will be for Outlook 2003 on a Windows XP computer.

Copy the names in Auto Complete to another computer

Important: You must exit Outlook before starting the following procedure. The names will be included in Auto Complete when you restart Outlook.

  1. On the computer with the saved Auto Complete names, go to c:\Documents and Settings\user name\Application Data\Microsoft\Outlook.
  2. Right-click profile name.nk2, and then click Copy. Tip: You can copy the file to removable media, such as a floppy disk or a CD, and then copy the file to the correct location on the other computer. Or you can attach the file to an e-mail message and send the message to yourself. On the new computer, open the attachment in Outlook, and then save it to the correct location.
  3. On the computer where you want to populate the Auto Complete feature, copy the file to c:\Documents and Settings\user name\Application Data\Microsoft\Outlook.
  4. If the Outlook user profile name is different on the computer where you are moving the .nk2 file, you must rename the file with the same Outlook user profile name after you copy it to the correct folder. For example, if you move Joe Somebody.nk2 from the original computer with an Outlook user profile name of Joe Somebody, and you copy the Joe Somebody.nk2 file to the new computer, you must rename it with the Outlook profile name being used on the new computer.
  5. When prompted about replacing the existing file, click Yes.
  6. Open Outlook to view changes.

Note: The file is often called default.nk2 or outlook.nk2
