Surely you want to have good digital communication? And surely you want Teams to help people communicate really well?
But it sounds like you are satisfied with Teams. It appears you have low expectations of communication.
You've read the problems people have posted here. Such as when working with multiple companies different teams. So as a starter, a choice of teams clients is missing. Next, teams is not an open standard. To allow connection with other non Teams networks. Next, Teams attempts to integrate your information. But only allows files pictures and text. Information is so much more. It could be a date, an invite, an invoice, a question, a holiday, an insurance.
If it helps, understand that non IT people want to manage this information in a direct, non IT, non text way. MS products rank very low in this regard.
If all you can imagine is what MS has, then maybe you might understand when it's put in front of you.

You’re still not giving specifics or making any sense.

“Information could be a holiday, an insurance”

What on earth are you talking about?

Those are the sort of pieces of information people actually have, and need to manage digitally. There will be ways to do this, where you see your information. Not files, or other IT mechanisms. You can create, sort and share them directly. They will have security, and ways to automate processes. You won't need 10 different applications to do this, or 6 incompatible online silos, or 4 different folder structures to organise it. Just one. Much less to learn, as you use one thing every time. And all using 90's tech.

You’re a master of stringing a very large number of words together without actually saying anything of any meaning.

You still haven’t given a single specific example of what you’re talking about and how Microsoft’s products don’t allow it.

So the requirement is to display information, such in the examples I gave. Where you can create new, edit existing ones, organise them in your preferred structure, and actively share them. All without doing unnecessary IT operations. All in one UI environment.

So……OneNote.

Avoid confusing information with text. Avoid forgetting about open standards.

You can insert whatever information you want in OneNote - music, text, video, photos, whatever.

Read back to the types if information I've been talking about. Real world things people actually need. Things that need to be shared with people who might not use One Note.

Mate honestly you’ve been talking jibber jabber “I am so smart” type waffle in every single post. You still haven’t given actual examples of what you’re talking about, what it would look like, or how it would be done.

I’ll give you one more reply and if you post yet another hundred words that say nothing, I’m out. What would this magical all data encompassing product look like to you? How would it work?

Avoid being rude please. I've been patient, and tried to explain in different ways for you. I'm sure you'll get it when you see it.
