I have just updated my Galaxy S2 software. Before I had a "calendar" (to be honest I never knew what kind of calendar it was, as it simply appeared on my main screen, it was the default calendar on my galaxy S2). Never had a problem with Microsoft Exchange Server, it very nicely pushed data on both calendar and emails between accounts. Since I updated my Galaxy software, this "calendar" is no longer there, now I have S Planner as a default. While email sync works well between outlook and my phone, calendar sync seems to work well only in one direction: events I input on Outlook will be pushed to the S Planner, but not the other way round which is very annoying. This is not the only problem with sync I've had since updating the software: I used to be able to see both Outlook and Yahoo emails on my "email" on the phone. Currently, I cannot. My email will not sync with Yahoo. Luckily I have a Yahoo app, but to be honest, it doesn't notify me of new emails, so it's a pain to use, as I have to open it constantly to check. This is less annoying than the calendar issue, though. Any help?
