We have improved the instructions for a manual workaround fix for outlook experiencing display issues. If you are still having issues viewing or creating email messages in outlook, please go to https://www.neos.co.nz/downloads and follow the instructions listed under "MICROSOFT OUTLOOK FIX". An alternative way is to use the web-based email client provided either by Neos or Microsoft.
Latest update from Microsoft "We’re investigating available data to isolate the root cause. Users with access to alternate protocols like Outlook on the web or Outlook mobile can use those as a potential workaround in the interim. More details can be found under EX255650 in the admin center." we expect further updates at 10:30AM.
