I just upgraded my Storm from OS 5.0.0.328 to OS 5.0.0.419. Since the upgrade my Microsoft Office tasks do not show up on my calendar. The menu setting within the calendar shows task to be displayed ... Suggestions? Battery pulls and reloads have been done, all to no avail.
Sometimes after loading a new app or installing a new OS the default service changes from Outlook to another calendar such as Facebook. On you phone go to Options>Advanced Options>Default Services and be sure that your calendar is set to the one you want. This may be your email account.
