Peak Outlook was 2016, right before the 365 mess.

I heard excel guys say peak Excel was 2010.

Where there any genuinely useful features Outlook 2016 had over 2010?

Mostly memory management and 64-bit support finally being on-par with the 32-bit versions, but it's hard to argue the nuance overall.

The switch to hardware-accelerated rendering was poor. It's still causing issues today. Is it the graphic drivers' fault or their poor implementation? Who knows, but they also disabled the switch that allowed to turn it off, which is just classic Microsoft being annoying.

I'm an Excel guy and 2013 was an improvement over 2010 with very little to dislike.

XLOOKUP was introduced in 2019. I thought it was a great update

You can take LET and LAMBDA from my cold dead hands

I wouldn't trust an "Excel guy" who said that, they aren't staying current/using new functionality.

Just off the top of my head:

IFNA, FORMULATEXT, DAYS, CONCAT, IFS, SWITCH, XLOOKUP/XMATCH, FILTER, UNIQUE, LET, TEXTBEFORE/TEXTAFTER, LAMBDA, et al.

But my favorite improvement is the "don't intentionally corrupt CSVs" options found in Settings -> Data -> Automatic Data Conversion (hint: Disable everything). Only took them 30-years to add that. Absolutely absurd these are enabled by default still.

Excel is one of Microsoft's best pieces of software and one of the very few they haven't turned into slop YET. Still don't understand why we don't have local-only Python to replace VBA at all license levels (i.e. non-cloud).

It still butchers long strings of digits if they are more than around 12 and less than around 15 digits long, its very annoying still.

Also textjoin and textsplit and the whole spill functionality.

I gave up on Excel for working with CSV years ago, but it sounds like I need to go back and try again. It used to drive me crazy how the import function was all "just fuck my shit up, Fam" every time.

Reminds me of the old joke about it: How is Microsoft Excel like an Incel? Both think everything is a date.

If i was in charge at MS, I'd go full return to monke and put a lot of devs into making winforms work great with 4k and high DPI. Then rebuild the most critical apps with winforms using a new layouting engine and some wpf concepts carried over. Nothing new or fancy, just old but gold.

History shows that there have been many Microsoft executives with a vision of building a new, perfect GUI toolkit. They all were released half done and quasi supported to this day.

I mean like you take the old thing and enhance it a bit but dont make a new thing from scratch because the idea and architecture has always been perfect. Most GUI toolkits from microsoft are drilled for ease of use so you dont have to have many devs to get something running (looking at dual way data binding and xaml). Imho thats the wrong approach, make it perfect for experts and approachable for juniors, winforms was very easy to click together, WPF not so much, too much framework magic.

Anytime a relative installs a new machine I get the call "What is wrong with outlook?". It's always "new".

That is why I said the 2x improvement about Webview they said earlier doesn't matter. And I believe the 10sec already accounted for the 2x improvements.

>the new Outlook uses between 490 MB and 636 MB of RAM while idle, with individual sessions varying based on mailbox size. Outlook Classic, doing the same job, uses around 117 MB to 148 MB at idle. A roughly fourfold difference.

In the old days, we would have cried about 150MB memory usage idle as being bloat. Why isn't it 30 to 60MB. Now 150MB is still so much better than 600MB.

I am not sure if Native will ever win. I do wonder if we could somehow make webview, or may be a subset of webview that is as fast as native.

I'm curious how much of those 150 are things that can't be boiled down to 'text', since that should be roughly the same size as on completely un-bloated software. The database of emails, the plain text of said emails, and all the basic UI should all be nothing but text and take up next to nothing.

Images on the other hand. I'd imagine Outlook Classic hasn't been made with 1 MB PNGs for all their icons, so it's probably not that that's pulling the memory usage, although it's probably contributing. Meanwhile, New Outlook (New) probably didn't optimise a single thing, so it probably is using 1 MB icons, which then quickly piles up. Not to mention the whole webview rendering backend, since we apparently can't make anything without going through a few layers of abstraction first.

Why are you not on thunderbird yet? Why do you get Windows notifications? Are you using Windows? I don't understand how there are people who can notice such things but still use windows in 2026. Also, please don't write with AI. This post was written with AI.

Often people have no say in the matter. Major of forced Microsoft usage comes from corporate IT. Corporate IT likes Microsoft because the amount of tooling available to manage it. Often these same people run Linux or Mac at home.

Rest of the people do not know the difference or know how to change out the software with better alternatives. Example, Firefox keeps loosing customers to Chrome and yet Firefox fully supports Manifest V2 with proper Ad-Block support, which increases computer security. Show these people an Ad heavy website with Chrome vs Firefox & U-Block Origin, this looks like magic to them.

Personally, you have to pay me to use Microsoft products. I have been game exclusively on Linux for nearly 10 years now. Before that, 5 years of dual booting just to game.

My first week at a new job that forces me back into Windows (with WSL). I'm about ready to throw my machine out the window and follow after it. I understand that a lot of the performance issues are things like crowdstrike and Defender and maybe some poorly configured network proxy stuff but Jesus, this sucks. I write embedded software for machines with 1 ten thousandth the compute of my dev machine, I should not be encumbered by issues like this.

I use Office 97 for this reason, it's like 400mb installed and everything happens instantly. Grab a copy off archive.org!

Congrats to the new outlook team on the performance improvements, I certain it used to take 30 seconds to do it, and they've cut it to 10s !!

But seriously, can we please make desktop productivity apps not suck on windows? I started programming on windows, old school Win32 with a little MFC. Still have the super thick MFC book from MikeB somewhere in the closet. It was better than the alternatives at the time.

Now I look at the windows developer site and I can't even figure out what happened since I stopped Win32 programming at around 2004. It's a total train wreck of abandoned technology, each worse than the previous ones.

Office (and to some degree visual studio), used to be the lighthouse, best in breed application, often using api's that were not yet public and styles that were not yet adopted. I remember buying component libraries that emulated these to make better looking and performing apps.

I'd look at windows again if they would make apps not suck and be ones that the industry strives to emulate. Without that, Linux or Mac is just as good (actually better since they have decent userlands).

We’re still on old Outlook and I’m not sure what we are going to do when Microsoft cancels it. The New Outlook preview release came out 4 years ago. If it was ever going to not be a piece of crap it would’ve happened by now.

The biggest issue I have with new outlook is meeting notifications (reminders) on Windows.

I see a freaking loading screen with the Outlook logo for 5 seconds before the window is updated with the meeting name along with a button to dismiss it. Yes that's everything in there.

How does Microsoft think this is ok?

Clicking a Teams meeting link from Outlook Calendar opens the pre-meeting screen to allow enable/disable of camera/microphone, plus it also loads up a little reminder window with Join and Dismiss buttons _over the top_ of the Join button of the pre-meeting screen.

Every time.

And then there's the fact that, if Teams wasn't already loaded, you can be up five minutes late for a meeting waiting for Teams to roll out of bed despite having clicked Join bang on meeting time.

I don't have the most up to date system at work, but it feels like 90s wait-computing.

Quite often when I use a 1990s system, I encounter several things that are instantaneous, while modern machines take several seconds.

Like, sending an empty folder to the bin:

Win 10 this afternoon took seconds to display a dialog box with no content, the a couple seconds to add a progressbar, then a second to add the cancel button, then multiple seconds to finish showing progress.

But at home a 1991s system with System 7 completes the same task instantly without needing a progressbar.
