Well, I am having a problem with Hotmail for Android app. I can sync normally my email, but calendar doesnt syncs anymore. I dont know what is happening and I dont found anything using google. I dont use the Contact sync option, but email and calendar yes, from which calendar is not working. On my Windows Live Calendar, I have multiple calendars on it, but only the main one, doesnt syncs, the others sync with no problem. Its the default calendar that has the issue. Thanks!.
