Using older versions of Outlook for Mac for personal email and calendar
I've 2 Macs: one with the latest version of every thing and an old iMac (iMac 27-inch, Mid 2010) with old versions (MacOS 10.13.6 and Outlook 16.43.20110804). They are both behaving the same which suggests it is a back end change made by Microsoft on Monday or Tuesday (AST) so maybe Sunday on Monday US time.
I've kept on pressing auto-restart so Microsoft should have lots of logs to analyse. It is different threads that crashes each time and it does make some progress with each run but doesn't stay up long enough to compose an email. This make it not fit for purpose and in breach of Australian consumer law.
Please fix this ASAP
