About mailbox.org Guard and Mailvelope

As previously explained, Mailvelope is an alternative to mailbox.org Guard. If you are currently using mailbox.org Guard, migration will require some additional steps to be performed first.
In this case, please go directly to the section "Migrate from mailbox.org to Mailvelope" further down below and then come back here afterwards.

Note that only one mechanism can be used at any one time.

See the screen shot below. In the column titled “Encryption Expert with Mailvelope“, please click on the button "activate now".
