Teams should respect Windows Focus Assist settings. I'm not even sure how apps are allowed to override Windows settings like this.
I put Windows Focus Assist into Alarms Only mode so I could record screen captures and I Teams kept popping up notifications over my application. I had to completely exit Teams so I could finish my task.

Every channel should have notifications auto-enabled, which could be muted at the user's liking. Muting could be enabled/disabled in the admin center in the event that a channel is of great importance and needs to send out notifications to everyone. In the attached screenshot is the option to "Notify me every time there is a new post in this channel". This should just be automatic.

Ability to notify everyone in a CHAT thread with the @everyone tag is needed.

Would be great if admin could monitor keywords similar to yammer. entering key works that if typed would notify admin.

Better reminders for meetings

Notification should be come in conversation tab when any body upload a file on team. Other wise other team members don't get the update about that file.

Currently, there does not seem to be any notification on any platform when a message in a Team/Channel is marked Important. Please put an option to be notified for important messages, even if you aren't actually mentioned in the post.

Since everyone use the same ringtone, you sometimes do not know that your phone is the one ringing

Do Not Disturb should block all notifications and I'd love to be able to schedule DND, like on Slack

The sound you updated to during the week of March 6 is HORRIBLE. Please give us an option to change sounds for chat notifications the same way we can change sounds for the phone calls

Focus assistant was turned on but notifications from teams (collegea chatting with me) were displayed as pop-up in the right bottom corner

We send/receive a lot of short messages that can be read in their entirety from their notifications. Since there's no way to mark a message as read directly from the notification, we basically have to dismiss the message "twice": clear the notification itself and then click into the desktop app to clear the red unread badges. It would be great time/click saver if there were a way to mark a message as being read directly from the notification itself.

When I set my Mac to "DO NOT DISTURB" Teams still pops up notifications. This is really annoying when I'm sharing my screen in a meeting.

It'd be nice if unread updates to a channel or direct chat would result in a persistent banner that would stay on screen until I read the message or dismissed the notification.

Please allow for Banner notifications to have a function where the banner only shows who the message is coming from and not display text. This is a more secure/private notification function that is easier to recognize than a the desktop icon that blinks.

I, and many of my colleagues, do many presentations using screen sharing to potential customers. I share my primary monitor to the customer, but the second monitor is offstage. It would be most helpful to have a setting of where the banner notifications appear (on which screen/monitor). I like getting the notifications, but I need them to show up "offstage" instead of on my primary monitor.

Being able to set reminders for messages received, whether it be a group chat or private. As simple as hovering over the message and maybe clicking a drop down box (where other options such as edit, save, or delete message would be) then clicking "set reminder" and then just set a desired time.

I have checked with Microsoft Premier Support and they have confirmed that users will only get notification for missed calls in the Teams app. Email notification is only for the missed messages in Teams, and this is the expected behavior.

But I found it strange why only calls are being excluded from email notification? Isn’t calls more important than message as people can always send email as alternative to chat?

Furthermore, Team’s setting is called “Missed activity emails”, which the missed calls fall under, this is very confusing to users.

Please include missed calls in email notification!

On the far bottom right small icons, can we get a little red flag or something when there are unread messages. Like in Slack.

I am unable to get any pop-up notifications on my phone from the Teams app. I have checked the following settings: On the app:
Menu/Settings/Notifications:

Send Notifications - "Always, even if active on desktop"

Push Notifications - All selected

Sound - set on with vibrate

On the phone:

Settings/Notifications:

Teams set to notify

Advanced:

Allow Notifications selected
