Will Patisco change my existing emails after I connect my Microsoft email account? Will replies sent from Outlook also sync?

1. Before connecting, you can read the explanation below the email connection button: existing emails will remain in your mailbox, and Patisco will not mark them as read, move them, or delete them. 2. Emails sent from Patisco will appear in your email account's Sent folder. 3. Replies sent directly from Outlook to your correspondent will also sync to the same discussion thread in Patisco.
