#32It's worth noting that this appears solely to be a failure with Office 365/Click-to-Run-based installations. If you buy your software instead of subscribing to it, and service Office with traditional Windows Update mechanisms... everything is fine today. This is what happens when you rip out well-tested IT infrastructure that has a reasonable update distribution process and entrust the cloud to update your software f…
But the salesguy said these things wouldn't happen!

#33I am constantly amazed at the number of bugs and seemingly obvious UI issues pervasive throughout microsoft products. It feels like their product philosophy is "jack of all trades, master of none" - they try to support so many uses cases that there isn't a cohesive best practice anywhere.

I feel like this has only really been the case since about 2015, so instead of ascribing it to a "jack of all trades" philosophy I believe it can be more readily explained by a "lets hire a bunch of webdevs to work on our desktop OS" philosophy.

#36I don't know if the article mentions this because (ironically) Bleeping Computer is now down, but you may be able to fix this by holding Ctrl while opening Outlook in order to start it in Safe Mode. Whenever I'm in a broken state, I do this, load it up fully, close it again, and start it normally. Then things usually work okay.
I had to do that this morning on my work machine, not sure if it was related to this issue.

#37If you're on Office 365, the Outlook web client is great ( https://outlook.office.com ). In fact, I haven't used the full client since 2015, except for rare cases. Or, you can enjoy the quiet while email is down :)
I have users that seem to have redirect loop issues with Outlook Online related to this outage. But I do agree their web client is nice :)

#38Earlier quoted context omitted.
The article was edited to add the directions well after my comment.
My apologies.
No worries at all - they didn't even mention that the article had been amended, so most folks finding this HN thread now will likely feel just as you did. I appreciate your comment, as it alerted me to the fact that there is now an all-in-one page with a good overview of the issue and workarounds that I can share with others.

The article mentions this, but it says that apparently, with this specific bug, you also Have to hold Ctrl every subsequent time you re-open Outlook - it’s not a one-off fix. They suggest going back to the previous release as an alternative.

#40I wonder if large companies get more of a pass with outages then small ones? Bias towards authority in a way. If a service has a big enough base an outage could almost seem like a pass for everyone. “Oo couldn’t do that this morning GITHUB was down.” Whereas if my small GitLab server was down bosses could be “well why aren’t we on GitHub like everyone else, it’s up now?” When google calendar was down a bit ago I trie…
I agree, but I think there's also a bit more to it. Thinking specifically of cloud infrastructure, if you run your systems on infrastructure that is also used by your largest partners and customers, then your outages will tend to coincide, so (a) nobody cares that you're down because they're down too, and (b) even if they did care, they're busy enough worrying about their own systems that they have less time to come…
Yeah that’s a good point, it also shows up in weird ways. Like when Facebook auth went down a slew of unrelated apps did too because they relied on it.
When I was younger I really wanted one thing to do everything, when chat was integrated into gmail is was like “oh boy, one less app!” And then similar feelings when it connected to SMS... now it’s just “great everything is getting more connected and homogenous and I seem to have less and less options”
