Why does Adobe Acrobat need access to your Google account?
When you add your Google account in Acrobat for the first time, Acrobat requests your permission to manage your files, your contacts, and manage drafts and send emails. Click Allow in both the permission dialog boxes, and then click Allow in the confirmation dialog.
Your default browser prompts you to go back to Acrobat to complete the send mail workflow, or the addition of Google Drive account workflow. Click Open Adobe Acrobat.
Your Google Drive account is added in the left pane under the Files section in Acrobat. If you have configured your Gmail account to send a file, then a draft email is displayed in a new browser window. Enter the recipient's email addresses and send.
