Important: Do not uninstall the Secure Mail application if you want to have access to old encrypted messages.
Secure Mail certificates are associated with a specific email address. This means that you cannot change your email address without first disabling Secure Mail for your mailbox.
If the UPN has been changed and mailbox has been reconfigured on different machine, content of previously encrypted messages can not be viewed without installing the certificate of Secure Mail for original email address.
To proper import the certificate and get access to encrypted messages on different machine, follow these steps:
- Before changing the UPN in HostPilot, export your Secure ID from Tools & Settings > ID & Password Tools > Backup / Export Secure ID to a PFX file > type in your Secure ID password and specify location and file name.
- Disable the Secure Mail in Services > Mailboxes > uncheck the box in the Secure Mail column for the user > click Proceed.
- Change the UPN for the user in Users > click on user's Display Name. Click on the current email address > type the new email address > click Add > move the Primary Address (UPN) radio button > click Save Changes.
- Enable the $Encryptedmessage in Services > Mailboxes > uncheck the box in the Secure Mail column for the user > click Proceed.
- Configure the Outlook profile with the new UPN and activate the Secure Mails per following instructions.
- Install the exported certificate from Step 1 on the new machine.
After these steps, upon accessing the Sent items, it will be possible to view the content of encrypted messages.
Note: Once you deactivate Secure Mail, you will ONLY be able to decrypt and view previously encrypted messages on your current computer. If Secure Mail is re-activated on the same machine but with the new UPN, it is not necessary export and re-install certificates as this is perfromed during the initial installation of Secure Mail
