Sending messages in Teams failed

I constantly can't send anything in Teams and have to reset to send messages again. I don't always realize it so people don't receive my messages, and I'm waiting for them to reply. Teams seems to be running but does not send messages/put me offline, without notifying me or the 'cross' by my name appearing in its own image. In the meantime I have already deleted the cache and reinstalled Teams. Anyone have the same problem and the solution?

    I have the same issue. Resetting/clearing cache/reinstalling the app only helps temporarily. The browser stops sending my messages sometimes as well. It's not a connection issue, vpn/firewall, small group chat, happens on individual messages too, and anything I've seen suggested/asked anywhere either doesn't apply to my situation or doesn't help. Having to switch version and sometimes use the one on my phone (on the same network, but always works) is causing issues at work.

    Same issue here for multiple random users. The only workaround is to sign out and sign back in, that lasts a few days before disconnecting people from Teams again. It started in the last few months.

    I've seen a couple of times a banner message along the lines "Please wait while we retrieve your messages"
    It never retrieves anything.

    Clearing cache, Resetting app, Reinstalling app does absolutely nothing to help this issue.

    User gets disconnected, they sometimes able to receive messages, but any that are sent by that user get stuck on the client side.

    Not related to group chats - can't send messages to anyone in any of the channels.

    It is not a network issue, people on different networks, on VPN and off VPN get this.

    Admin won't be able to help you with anything - Otherwise there would be more troubleshooting suggestions other than usual clear "cache", "restart app", "log out, log in".

    I don't think MS ever comprehends how frustrating it is for a business to lose sales, clients and orders, just cause your messages didn't send. Why should we not move to another supplier for cheaper, better version of this mess, that MS keeps peddling?

    Hi Eben,

    The problem occurs in both desktop and online versions. Also, it does not matter whether you send to an individual or a group.

    Thank you.

    Hello Nordy_L,

    Good morning! Thank you for posting in the Microsoft Community. We will be happy to help you.

    I'm sorry to hear that you're experiencing issues with sending messages in Teams. Typically you may fail to send messages to a group chat in Teams if more than 200 members are added concurrently to a group chat. Nevertheless, group chats can have up to 250 members, but this error may occur if more than 200 members are added at a time, also it can be network issue etc...

    In order to narrow down the problem for a better understanding of the situation, I may ask questions as follows. Thank you very much for your cooperation and time.

    1. Please may i know if the issue happens in both app , in teams desktop and teams web app as well ? check in your teams mobile.
    2. Please is it happens when you send message in specific group, one user or all your messages you send to all group and user?
    3. Follow these suggestions if Microsoft Teams has failed to send messages to a group chat:
      - Check Network Connection: Try accessing other websites or perform a speed test to check your internet connection. However, if the speed comes less than the plan you’ve opted for, consider restarting your modem and router or contacting your service provider
      - Log Out and Log In back into Teams
      3 Verify Group Membership check if all the recipients are members of the group chat. Messages might fail to be sent if someone has left the group or been removed. Also, make sure that none of the recipients have blocked you. Blocked contacts won’t be able to send or receive messages.
      - Clear Teams Cache Data Type settings in the search box, and then select the Settings app from the results. Select Apps > Installed apps, and then type Microsoft Teams in the search box. Locate the New Microsoft Teams app from the results, select the More options button (...) on the right, and then select Advanced options. In the Reset section, select Reset. Restart Teams.
      - Contact Admin  If none of these suggestions helped you, consider contacting the admin or the IT department. This is because sometimes misconfigured settings in the group can be why you fail to send messages to a group chat in Teams. They should check if there is any message policy.

    Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. Thank you for your help.

    We look forward to hearing from you. SincerelyEben | Microsoft Community Moderator
