I'm still having issues reconciling the calendar. I use BIS so my work mail comes to my BB 8820 and I accept the meeting on it and meetings I schedule I send a copy to my BB as well, but it then runs into issues where it is duplicating. I have worked from so many clean slates its becoming useless and more clear that I should use BES for personal and BIS for my work mail. We have BES at work I just prefer not to have my BB locked down and monitored by corp since it is not paid for, not reimbursed on or part of my job I just like being accessible on the go.
