Dropbox announced a handful of expansions for its business Wednesday, including Dropbox for Business service, updated versions of its Mailbox app, and a new photo syncing service. Last but not least, the company is adding a pro-wiretap board member.

The photo syncing service, Carousel, is a formalization of what used to be a Dropbox feature: the app could automatically sync photos taken from your phone to your Dropbox, making them available on all platforms (and, for some of us, adding significantly clutter to your Dropbox). Carousel itself is now a standalone app that syncs both photos and videos, but it's still supported on the back end by your Dropbox space; therefore its functionality is limited to the size of your Dropbox.

Dropbox also formally introduced the ability to connect Dropbox for Business accounts with personal ones. Dropbox for Business service has been in beta for a few months, and it gives companies features like the ability to administrate or remote-wipe content. Now Dropbox for Business accounts can be linked to personal ones so all the content can be accessed from the same apps.

In the Mailbox department, Dropbox announced new Android and OS X desktop versions of its formerly iOS-only e-mail app called Mailbox. Mailbox drew attention for its constrained sign-up process one year ago, and it was acquired by Dropbox while still in its infancy. Both new versions are available for free.

Lastly, Dropbox has added Condoleezza Rice as a board member, according to Bloomberg Businessweek. In 2003, Rice authorized the National Security Agency's wiretaps for members of the United Nation's Security Council at the behest of then-sitting President George W. Bush. Rice later defended the wiretaps. In the intervening decade, the NSA has taken many more magnitudes of liberty with such monitoring programs.
