A collegue of mine discovered this in markdown formatting (if you include a ">" before a paragraph it formats it as a quote, then 2xShift+Return to exit quote). This is a useful feature when trying to give context to a response that occurs later in a conversation thread.

Quoting should be a more integrated feature. I'm picturing a "quote" button below the message window that when you select it, it opens another window where you can select a message you want to quote. The tool should automatically date/time stamp the quote, format it the same as the markdown method, and perhaps make it so that clicking the quote would bring you to that part in the conversation.

I would like the ability to reply to a specific comment within a thread. Especially now with Guest access and Team sizes sure to grow and expand.

I was in a "Conversation" with several people the other day and the problem was that people kept starting new threads rather than replying to the thread. This was because the threads themselves were quite long, and the only reply button was way, way down, past dozens of other comments by several people.

Sometimes you just want to reply to one specific message/comment in a thread rather than at the end of the thread to answer one question or comment on something in-line with the conversation.

This is especially important when dipping in and out of conversations or moving between threads and now between Teams tenants/accounts.

MULTIPLE USERS reporting offline needs:

Generally want to use Teams offline:

If I am offline it would be great to browse through Teams and Channels in case I have to lookup some informations.

Also viewing the latest notes in "Notes" on teams would be great.

It would be enough to have "Read only" - for the moment my Teams app does not even open when I am offline

Compared on my mobile - I can read all posts while I am offline.

Edit while offline:

just been using teams wiki to take and share notes in a meeting. when the connection dropped we were all kicked out of the teams application and weren't able to read what had been put. when the connection came back up, half of the notes were missing. There needs to be better handling of offline mode and a way to carry on working and sync changes when the connection comes back or at very least a way to read offline

Sending messages to offline contacts:

I had thought this was already the case, but it would be nice if we could send private messages to Teams contacts who are offline, and have that message pop up for them whenever they next log in.
There are instances when I have a thought I would like to share with a co-worker and it would be helpful if I could send them a private chat message that they will later receive, regardless of whether they are currently online or not.

Access files offline:

I need to do this on our construction sites.

CHANGE PROMPT:
Change "Add team" to "Add or join a team": I avoided this button because I thought it would always create a new team. It wasn’t evident to me that I could browse for existing teams there too.

PREVIEW A TEAM:
Provide the ability to preview a Team without immediately joining, to see what the reason for the Team is and what Channels exist. It’s a little cumbersome to have to join, realize the Team isn’t what you thought it was, and leave.

TEAMS DISCOVERABILITY
Presently you have to know the name of a team to be able to search for it, if I am new to the company and I want to have a look to see what teams there are within my organisation I can’t currently, as I don’t know the names of them in the first place, it would be better if all public teams were visible.

One of the defining features of office down the years has been the proofing tools (i.e. Spell checker, theasaurus, autocorrect, grammar checker). I would love to see these come to Teams.

The way I envisage this working is as I'm typing a message the famous red/blue/green squigglies that we've all become familiar with should show up.

Most of all I'd like autocorrect (i.e. a spelling correction that I've used previously automatically gets applied as I type). Stretch goal for this, have a single set of autocorrects that work across all of Office 365, including the client apps.

Some people might think that such tools would not be applicable to a lightweight tool such as this (I would disagree, but everyone is different) so perhaps there should be the ability to toggle proofing tools on and off.

It should work across all Teams clients (i.e. desktop/mobile/web).

I must admit I'm not a user of Teams yet (although soon will be - our org is turning it on soon) so for all I know some of these things already exist - I somehow suspect that they don't all exist yet though. Most of all though I'd like the autocorrect feature and the red squigglies.
