PGP Desktop for email

Hi Guys,

We have a team using PGP for encrypting emails which works well apart from one problem.

They all have a team mailbox attached in their own profiles in outlook and need to be able to send and receive emails via the team mailbox. I have managed to get reading encrypted emails from the team mailbox working but they are unable to send encrypted emails back (using the team mailbox).

I created a policy in PGP to use the secondary mailbox's private key to send but it doesn’t work.

Please assist.

Thanks

Mat

PS: They all have full mailbox and send as rights to the team mailbox.
