Android exchange calendar not updating
Read the Knowledge Base article Setting Up Active Sync On Android Devices for more information.
One of the most common issues I come across with business users and Android smartphones is Exchange contacts and calendars not syncing.This can be very frustrating, especially since not every Android device is created equally.With different release numbers, different provider platforms (Motorola Motoblur vs. Samsung Galaxy), and even different installations of Exchange, it can easily become a chore to keep this feature working. For all of the above account types, you'll need to add it as an EXCHANGE ACCOUNT.This can also be called: Corporate, Enterprise, (Microsoft) Exchange Activesync, etc. (If you don't see any of these as an option, please make sure that your stock email and calendar apps are not disabled on your device).
