i tried to search online and they were talking about the identity, so i search my Microsoft user data folder and found under Office 2011 identities i found many identities as the screen shot:

do i need all these identities? specially it's eating a lot of my hard disk space. 

i am using OS X 10.10.5 Yosemite and outlook 2011 version 14.5.4 (150722).

  ... any idea how to help?
