Compose message field intermittently loses focus and transfers keystrokes to Calendar Event

Question

Compose message field intermittently loses focus and transfers keystrokes to Calendar Event

Shaun Woolf 10

So over the past few weeks, I've noticed a strange issue in the online version of Teams. If I'm composing a message in Chat, the compose field will occasionally lose focus and whatever I'm typing is no longer appearing in the field.

That's not the weird part.

The weird part is that instead of appearing in the message field, my keystrokes are being registered in Calendar as the title of a New Event. I only discovered this because random events with incomplete words and sentences were appearing in my calendar. This has happened at least a dozen times over the last 2-3 weeks. Because the focus is being shifted within the app (and not to a different application altogether) tells me that this is likely an isolated issue with Teams Online itself.

I've not discovered this doing any other action in Teams (although, you don't really type anywhere else besides Calendar) and I've not noticed that it is any particular keystroke that triggers the issue, so it's difficult to reproduce.

Anyone else experience this or am I going crazy?

This has been happening to me for months and is so annoying!

Only happens in Teams in the Browser - typing a message to someone and randomly the cursor disappears and I find out later the text I was entering has been used to create a Calendar entry. Seems like the focus has moved to the calendar tab but the screen has not. On most days, this seems to happen fairly randomly but often - maybe every 10 mins or so on average?

I mentioned this on a work call and at least half a dozen other people have the same issue. This is on a range of Windows 11 devices using Edge, across multiple tenancies. I've several Edge Profiles setup and it happens in all of them (not tried another browser) - one of which has no extensions.

Our whole team has the same issue. And it happens on all the Browsers including Edge running the Teams PWA.

Hi @Shaun Woolf,

I hope you are doing well.

Thank you for taking the time to describe the behavior so clearly. That definitely sounds unusual, especially since the text appears to be redirected within Teams instead of simply disappearing. Since the issue seems intermittent and difficult to reproduce, a few environment details would really help narrow down whether this may be related to a specific device setup, browser session, or local browser configuration.

To help look into this more carefully, could you please share the following details:

What type of device are you using when this happens, Windows or Mac?
Which browser are you using to access Teams on the web, such as Microsoft Edge, Google Chrome, Safari, or Firefox?
Does this only happen in one browser, or does it also occur in another supported browser?
Does the same behavior continue in an InPrivate or Incognito window?
If you use browser extensions, are any of them enabled while using Teams?

Once I have this information, I'll be able to share accurate and targeted solutions for the issue.

Thank you for your time and understanding during the troubleshooting process. I'm looking forward to your response.

I have the same issue using MS Teams Web/PWA with Microsoft Edge(Version 148.0.3967.83 (Official build) (64-bit)) on Ubuntu LTS. It keeps generating calendar events based on input i write in teams chat.

how to reproduce: login to teams web, i use: (https://teams.microsoft.com.mcas.ms/v2/). goto chat, start writing to a person. the cursor in the chat oftern disappear and whatever you type will not be shown, but will added as a calendar event. clicking the input box in the chat will return focus and you can write in chat again. but it may loose focus multiple times.

I'm seeing the same issue with a very different setup. I'm using qutebrowser on Linux. Qutebrowser is based on PyQt6's webengine (which is itself Chromium-based like Edge). The problem happens very consistently -- if I pause typing for a few seconds, focus seems to shift to the calendar -- to the point that the Teams web app isn't actually usable for me with qutebrowser.

I'm not mentioning this because I expect much support for my odd setup, but because I think it might be worth knowing that the problem affects multiple platforms.

There's a GitHub issue open for qutebrowser: https://github.com/qutebrowser/qutebrowser/issues/8899
