It would be really helpful to add more ways to notify teammates on through planner:
-Tag teammates in Planner Card comments
-Push notifications for mobile when mentioned in such tags.

Automatically set status to Do Not Disturb/DND when presenting or sharing screen like on Skype. It's very inconvenient when banners for personal chat notifications come up during meetings, sometimes the content is not to be shared with others. If not that then allow for the option to not show actual text in the banner notifications.

Download Improvements

Generally the download experience with Teams is pretty poor and I'm amalgamating suggestions in to one

- Configuration of download location other than default download folder
- Download progress and fixing of hanging UI when downloading file
- Permanent notification to user in chat/team room or even a downloaded management area showing downloaded files with a direct link to open file
- Ability to open file directly from notification
- Ability to open folder from all areas download is listed
- Ability to download to a different one time location from the file hamburger menu

When using Flow to post a message to a Team channel, the @mention does not trigger a notification. The text of the message is simply the "@mention" that was typed. Please enable a text recognition of @mention to enable the notification as though it were being typed directly in Teams.

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.

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

Better reminders for meetings

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

Instead of using a custom notification, please use native MacOS Notification manager. This will allow users to manage notifications consistently with most other MacOS apps.

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.

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.

Right now (3/5/19 update) the only options for sound notifications are All; call, mention, and chat; Off.

I want sound notifications for call, but not chat or mention. Grouping calls with chats for sound notifications is odd - calls are usually important but sound notifications for every chat message is excessive.

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

SHIFTS: Notifications for upcoming shifts
StaffHub sent an email to the user assigned to a Shift, to remind them of an upcoming shift. It would be very helpful to have this as an option Teams.

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.

Create a setting to turn off "Member joined the team" and "...removed Member from the team" posts in the General channel.

Ability to mute individual channels so you dont receive notification to them

I would like a setting to turn notifications on or off based on a timer so that notifications only pop up during set work hours.
