My Hotmail calendar was happily syncing onto my Blackberry Q10 calendar just fine until just a few days ago. Now there are no calendar entries on my blackberry although they appear on both my Outlook calendar and the Hotmail/outlook calendar on my computer. I tried deleting the Hotmail account on my blackberry and adding it again but it keeps saying there is an error. When I click on the tab on the blackberry to choose which calendar should appear, it says there are none. Does anyone else have this problem and does anyone else have a solution? I had been previously just using the Outlook calendar (not the website, the software) to sync with my old blackberry, but the service technician at Rogers told me to use the Hotmail cloud (which I know is now also called Outlook just to be confusing). He set it up and it worked fine until a few days ago. I called Rogers and they said they didn't know why the calendar wasn't appearing on my blackberry so I am stuck.
