Outlook Crashes Shortly After Starting

Jim I understand where you are going with this, firstly if you read the forum you'll see it wasn't a Mac OS update that broke Outlook. This was an update that Microsoft pushed to a client of mine, in good faith he allowed Microsoft to install an Office update that they were recommending for his system...which he has done for the past 9yrs of using various Macs. This time it cost him more than he afford to give, it's like Microsoft just shot him in the head.

But like you say...he should have first put his bulletproof vest on that fateful morning before turning his MacBook on, it's all his fault.

In my opinion we were not expecting this kind of bugs/changes crashing the product. Microsoft states: "Product functionality and feature availability may vary on older systems" and "....quality of your Microsoft 365 experience may diminish over time." I did understand in the way, that we were not receiving any additional functionality and may not receive security updates. That's fine. But essentially behind this marketing sentense above, its says in reality: "We can do whatever we want. If you don't update to the newest version, be prepared to loose any service at any time and don't call support for help because we are not going to do anything about it".

This would be more truthful and transparent towards us as paying customers.

I have around 65 Macs which could have the same problem at any time.... not funny at all! Troubleshooting identifying the problematic calendar entry is a nightmare due to poor logging mechanism within Outlook. So I have to discover it by trial/error.

I hope Microsoft decides to do one of the 3 possible things:

• Release a 16.43 Version with the fix in order that Office doesn't crash anymore
• Revert your changes on the Office365 plattform
• provide a detailed description of the bug so we can train our employees not to use that specific feature in Office365 which creates the bug

If I could update the OS on our Macs I wouldn't have this issue. I cannot.

The Microsoft website for Office 2016.

Operating system

Mac OS X version 10.10 or later

You have broken Office 2016 by doing something at your end. Your System requirements still state that 2016 will run under 10.10.x or above. Please issue an update for Outlook 2016 that will work under 10.13.x. Saying 'use the web portal until you can update' is insulting. Sorry, we haven't got 30k to drop on mew Macs because you've broken the functionality.

From Microsofts website for Office 2016:

Operating system

Mac OS X version 10.10 or later

It won't actually let you perform an update of an app that isn't supported by the OS you're running. The update pushed out by Microsoft has broken the functionality and all the checking in the world would not have indicated that the update would cause quite catastrophic effects.

Hi everyone,

This is very frustrating. I have reverted back to my Apple mail as using the web all day isn't great. I don't have the MS Teams integration I need and I was also using the tasks function of Outlook, so that I will have to visit on the web. This change from MS has changed my entire workflow and there seems to be no interest in a fix.

MAC OS 10.13.6 - Can't upgrade any further, machine doesn't support it

Outlook 16.43.0.201108 - I have also tried to uninstall and run older versions

There is discussion about Calendar entries causing this?

Has anyone made any contact to anyone else besides Qian, is he able to help us?

Simply put, something happened to Outlook and it won't run, we can't upgrade Outlook or Mac OS any further due to the hardware. Everything was working, then Outlook just started blowing up.

Thanks to everyone for their input here, the future doesn't look good with our existing hardware.
