I have just uninstalled Microsoft Office 365 for the 4th time
THIS YEAR.
I purchased Office 2016 shortly after it came out - note that I said Office 2016, not Office 365.
Microsoft decided that this would be converted into Office 365 somewhere along the line. They also decided somewhere along the line that my RETAIL key would be converted into a CLOUD key without my approval. So instead of just being able to use my license key, I have to be signed into Microsoft Account 24/7/365 so that they can track "telemetry" from my system and "reward" me with a load of bloated junk features that I never asked for or needed.
It has self-updated Excel in recent history. This morning I've come to investigate a fishy log file. What did I want Excel to do? Open Microsoft's OWN log file format from IIS; something that I have done 10000 times before. Well, apparently Excel has a new Text/CSV import module. Apparently it can't handle this. I can either have the first 6 columns from the log file, or gibberish. Unfortunately as I want column 15 or some such. I'm stuck.
Naturally, because it is using the Click to Run cloud installer rubbish, you can't uninstall updates. The Click to Run "downgrade" feature doesn't work; it asks me to confirm that I'm "connected to the Internet". The contrived level of its design
(along with Click to Run itself
) is obviously intended to prevent people from attempting to use it in the first place*. So I've wasted an hour and a half trying to solve that, uninstalled Office and it is now reinstalling back to default Office 2016** so that I can look at a BLOODY LOG FILE.
Now I've reinstalled the damn thing. I have to use the "account" section to disable updates. Of course Word/Excel etc won't let me INTO the account tab to do that, because it has updates waiting.
* You have to write config files and execute it in certain ways from certain locations - heaven forbid you could just double click it.
** Luckily back in 2016 I wasted lots of time with Click to Run's config file nonsense and cloned a snapshot of Office 2016 from the Click to Run cloud repository.

) to find that Microsoft had installed Office 365 for me alongside the already existing Skype for Business. How kind of them. Naturally I promptly purged the lot and reinstalled SfB on its own again.
