Using Classic Outlook on Windows for personal email, calendar, and contact management
I run the IT dept for our company and perform remote assistance for all sites. Ticket tracking shows only 2% of users that have stuck with the new outlook.
The failure to maintain this particular function is more than half the reason we are constantly asked to get rid of the new outlook.
This new outlook has clearly added support time to my staff. Outcome of a recent meeting I opened a staff task to find a way to kill the new outlook via group policy.
