Adobe Sign with Microsoft Teams - Signing doc's between Team Members

[richl88958607]

Hi there,

I have created a "team" in Microsoft Teams for office members within my organization to send me documents that they need me to sign. I have added Adobe Sign app to my Microsoft Teams. 

1. Currently I am the only one in the office with a paid Adobe subscription. Do all office members need their own subscirptions to integrate Adobe Sign into Microsoft Teams so that they can send me documents to sign?
2. Can we keep the documents within Teams to be signed and sent back to each other without having to utilize our emails?

Thank you!
