Scheduling and managing events using Outlook.com calendar
@FredLussier: We can not fix this problem ourselves. This problem is described in several active threads and from several users. In this thread alone, the problem was described as far back as June. It is not a matter of us doing something wrong or having inconsistent data. This is obviously a program error.
In my opinion, several moderators are working on this problem without coordinating their efforts with each other. That is why they keep privately contacting users. I only hope that the appropriate escalation has been made to the development team and that development is aware of the problem.
They need to know that it is a general problem, not relating to a user's account, choice of browser or contact data.
