Recently, I have been running into a situation where the default settings for visibility of emails sent into Pipedrive have been changed to "Private".  My company uses Pipedrive for everything from sales, engineering, finance, commissions, etc., so everything must remain "shared".  Currently, Admins don't have the ability to update key settings like this for all users.

Related to this, Admins are also unable to repoint emails that are sent into the wrong deal for users.  As I have in excess of 60 users, it can take weeks to repoint all emails if the error was over a long chain and multiple users.
