How does this work between company members.

Hi All. 

I haven't yet used the Symantec Encryption Software. The company is 3-4 members and needs to be able to encrypt sensistive data. My questions are:

1) How do we share the encrypted data amoung members in the company?

2) How do we use encrypted data on a third party machine?

3) How do we recover data in terms of any system failures?

Thanks in advance for any direction, description or advice in this area.

Regards,
