Outlook also has had this problem of emails just not showing up. Sometimes it takes a whole day for an email to arrive. Amazingly low quality for such a wide used product.

MS in particular has the habit of actually introducing small bugs like this regularly through their usual updates. It's infuriating. One day something works the next it just doesn't. I know people who never update their machine because of this. Can't blame them. Once it works, why take the chance of breaking it with updates? It it is a certainty that at some point MS will break some functionality of your system with an update. It's just a matter of time. So turning off auto update is the most sane thing to do for most people. I recommend it myself, and if you update your Chrome or Firefox automatically it is safe enough to use an unpatched Windows for most people anyway.

Once MS started introducing new bugs rather than actually fixing old ones I knew the last MS machine I will service is a gaming machine for my family. As long as that needs to run, I will make it run. All my other systems are on linux now. Once the gaming craze is over I will ceremoniously burn the Windows license key that I used, and I will never, ever, run any software from Microsoft ever again.

Except at work of course, but I don't mind getting paid to be frustrated.

HA!

I was just testing a VR app that has a Windows component when things started failing in VR. I took off my headset and noticed my test machine going through power-on self test.

"Oh crap!", I thought, "a bug caused the system to reboot".

Nope. Just Microsoft deciding it's time to apply some updates. Doesn't matter that I scheduled for a time that I wouldn't be testing.

I've NEVER been able to successfully gain control of this, despite reading up on it and doing all the recommended things.

This way has always worked for me

    %windir%\System32\Tasks\Microsoft\Windows\UpdateOrchestrator

rename Reboot files and add them as folders (you'll need to override file permissions).

I'm convinced the "schedule" thing doesn't actually do anything. It worked in Windows 8, and that's the last version of Windows where updating was (almost) tolerable.

I spend too much time sitting waiting for people to join meetings that have been cancelled or moved - and Outlook / Teams don't know yet. I'm connected - I know this because I'm sitting there 'in' the meeting. I'm receiving emails. I'm talking to people on Teams... Argh.

On the same note, it takes practically all day for the iOS outlook app to update my email. My organization doesn't allow for the default mail app to work anymore, so I am stuck with this worthless email app.

I've had that happen on Slack mobile so much I just don't trust it anymore. I always tell people (even if it seems counterintuitive) to email me when things are urgent because very rarely (or not, since I can't tell), it's decided not to show me critical messages.

I get that a lot. A DM arrives, there's a red blob with a number next to the sender's name, but the actual message doesn't appear.

Everyone I've talked with has experienced this, yet it's been a bug for years. I don't understand. Do Slack not use their own product?!

It absolutely did, it's only just started doing it recently. Drives me freaking nuts.

Mine is doing a variation of this now. If I’m on a call, messages stop coming through but I’ll see them on my mobile. When I end the call, they still don’t come in until I restart the app!
