Deleted Office 2011 and installed Office 2019. Now, I've purchased Office 2019 thinking the office install was hosed (I did not have the original 2011 pkg file to reinstall). Have checked for office updates, rebuilt the default profile and eventually created a new default profile, cleaned all of the caches using a program called Onyx-all to no avail. Word/Excel/Powerpoint work fine but in the Applications window, Outlook did not have an icon. Clicking on the icon would just bounce but never open, no dot beneath the icon either. After a crash while editing video the Outlook does not work. With that said, Outlook via Office 2011 was installed. I have an iMac user running Mojave, hesitant to update to Catalina due to some software he uses.
