My Sony 15" laptop was set up on Microsoft Exchange (late summer) and worked and synchronized perfectly until October 23rd. Subsequent entry did not rapidly connect as usual. Outlook since has only shown "DISCONNECTED" after frequent attempts to connect.

Desktop Outlook e-mail receives ONLY.

Previously, the Exchange e-mail did not recognize the I-phone as the log-in was a Blackberry format. The I-phone is connecting promptly after changing the corporate access from a BB to normal exchange access on October 1st.

1.] Did the change in the Exchange server from BB format cause the disconnect?

2.} What else may have "frozen" the access?
