We have outlook classic at work, and that shit takes a solid 5 mins to actually load up my inbox enough to become functional.

Outlook has always been shit, the new AI slop is just fuel on the fire.

my work computer runs linux, so only o365 webmail outlook, and it's... somewhat functional but the damn ai creeps in on every occasion.

automagic autocorrect that can't decide if I'm typing english, finnish, or mix of both when the occasion needs it? Nah, autocorrect it wrong 100% of the time. But I did find a toggle for it after few weeks.

the apps menu to open eg. teams when needed? only options are copilot and "other apps" - which is also copilot.

not that I need teams that often, but wtf. I started using a bookmark rather than navigating the menus.

Then you have slow* computers, or an inbox of 50GB+ of emails over the last decade. I've got about 20k (maybe around 15GB) email after archiving a bunch of data to a .PST, and it's much snapper.

I have to hang onto my old emails, but I'll archive to a local file since I don't need them all the time. I do it by every year, it's very helpful, makes Outlook Classic very fast again. The nice thing is the archives go into the Documents which is then backed up through OneDrive.

My department has a service that is abbreviated to PM. Since our organization uses Google for mail, I often have to battle with automagic corrections to every use of PM as a noun to "the PM".

Check the plugins list. Some companies have a few.

The only solution, as you might’ve guessed, is the move to WinUI. We already reported that Microsoft is now fully committed to WinUI, with Rudy Huyn preparing a team to make native Windows apps, and so we may see a native Outlook too…

One can dream. The prevalence of web apps pretending to be native apps is unfortunate. Just because your devs “know” JavaScript doesn’t mean it is a good language.

Oh, I love "other apps". My Teams once decided that obscure features like chats and calls belong in there.

Yes, Teams. Put your core functionality out of sight. That's exactly what I wanted.

So we are going ful circle back to native code, that has worked much faster for decades.

Web technologies on desktop applications was always a bad idea.

If only managers/IT could see how amazing Linux is.

The productivity gains I'd have from the speed of Linux on my work machine would be noticeable. Plus my mood would greatly improve.

Windows (especially slop 11) cannot handle how much I do at once. My brain is faster than the computer now 😅

and tout it as an advantage! In reality it's only more convenient for the dev, and just uses up more resources and have more moving parts on the client side

Outlook classic loads instantly? No that’s a lie. It’s never loaded instantly.

Modern Outlook isn’t great but it’s a leap forward. It’s also browser based, which is good for alternative OS folks.

Outlook used to download emails to a local folder. Opening email was literally as fast as your computer's HD read speed.

That is no longer true.

Also, no one is going to use microslop products on alternative OS. That's an insane take.

Modern outlook downloads messages too, maybe you haven’t used it.

Many companies won’t care about end user os but are deep into the m365 ecosystem.

What are they transitioning to? It seems difficult to fully escape MicroSlop in the office environment and get everyone onboard, especially when my IT group double checks everything they do with CoPilot first. 😡

The average office worker cannot differentiate between a file explorer and a web browser. I wish corporate jobs could switch to Linux over Microsoft.

God, I wish I could upgrade the work computer to Linux. Unfortunately, we need software that is Windows only, and having to virtualize it counterats too many of the benefits

Opening an email via the web can never be as fast as opening one via a local cache.

Also, taking more than 10 seconds to open an email is just insane on its own.

Old outlook took forever to launch, and would sometimes hang for no god damn reason, but at least it would somewhat instantly open an email.

New browser based, slop injected outlook opens moderately quickly, but still hangs for no god damn reason and can't open an email from notification in less than 10 seconds.

If not for vendor lock in and paid(?) shills, no one would ever use that garbage.

It's a feature.

Try fastmail for how to build an instant Web interface that is just ridiculously fast. Everything is instant, it has offline support, email address aliases... I dont know. Couldn't be happier. I literally have nothing to complain about at all.

Except yes, it's part of the five eyes countries, which means every email is likely also in nsa datacenters. I dont like that, and would prefer it not to.

If only we had the technology that would allow us to compile software into an intermediate language and provide a runtime for a multitude of operating systems, instead of running everything in a fucking browser. That would be so cool, that way a text editor would not need 2 Gigs of RAM. And maybe outlook would not take ages to load

We could name the technology .net or something. Or maybe name it after a coffee bean.

You are correct. Explaining our server vs onedrive/teams/SharePoint is a losing battle with most of their eyes glazing over if you try to explain.

Gross.

Thankfully our management is wary of slop bots (though they allow use of it in scenarios where you aren't inputting data. Which is like every scenario soo, its useless) This however upsets the Young's that think everything should be done with slopbots (spoiler, their work is shit)

Outlook Classic does that, but Outlook Classic is going away in favor of a web browser pulling up outlook.com

That's what this whole article is about. The fact that under new outlook, clicking on a notification will take however long it takes, 10-seconds in the article itself. And from what they said, they did the tests repeatedly.

Because it's a not a mail client, it's a web app, and those are slow.

I use modern outlook daily. It’s not any slower than classic, especially when classic has any addins.

In fact it’s faster to open.

It’s better on your cpu/battery.

If you keep all of your email in your inbox like a lot of Outlook users do, it’s much faster to switch between folders and search.

Modern doesn’t fall apart when using shared mailboxes or archive mailbox like Classic does.

It’s awful at public folders.

It’s not great at browsing (not searching) for older messages as they load dynamically as you scroll after about the 3rd week.
