Re: University credentials used by third parties

["Flynn, Gary - flynngn" <flynngn () JMU EDU>]

To add to Adam's stated concerns, even sharing email-only credentials are
troublesome these days. My decision to provide my Exchange credentials to an
outside party would give them access to other people's calendars, shared
mailboxes, and possibly data storage areas like Skydrive and Live Office or
the Google equivalents. Not to mention being able to send 'OMG, is this your
picture posted ON THE WEB!' through Messenger. :)
