Is your Device ready for Office 365?

Windows Users  if you have Office 2013 installed, you are ready to go. ISS would advise for both versions to install the latest Windows Updates for Office also to ensure you have the most up to date security updates.

Apple Mac Users must have at least version 14.4.8 installed. To update please see our instructions here. Note that Microsoft updates Office often so it is likely that you may be offered an update that is higher than version 14.4.8. If offered this, simply install this higher update.

Users of Multiple Devices such as a laptop or Macbook should ensure that the software is up to date on these additional devices also.
