we'd like to announce a new software product named UnifiedGroupManager for Office 365.
Currently adminitrators can manage Office 365 groups by Office 365 admin center and by PowerShell.
The first method is more convenient but it has some functional limitations. PowerShell is very flexible tool, but not so convenient.
UnifiedGroupManager application provides user interface to change the settings of existing Office 365 groups. It is a Windows-based desktop program.
A remarkable feature of the program is its ability to provide bulk update operations. For example, you can change "@domain.com" to "@domain.org" for each SMTP address or set the same value of "Language" property for any amount of groups.
