So today at some point after 2pm (because I successfully added something to my calendar then) I have lost the ability to add stuff to my Exchange Activesync calendar which used to be synchronised to my Google apps calendar. All the old stuff is still there and the Inbox is syncing fine. If I go to the setting the tick box to show the exchange calendar is missing. If i add something online it does show up on my phone. I can even open stuff and read it but i cannot add anything new. Please help. Saying "remove activesync account and re-add" is not a solution. I shouldn't have to keep doing this every few days to sort syncing issues.
