Issues with message delivery delays in group chats in Microsoft Teams

Dear @juan perez,

Good day! Welcome to Q&A forum!

Thank you for your detailed information and for doing standard troubleshooting process! I really appreciate it!

To understand the situation better, could you confirm the following information:

• Are the same users always affected?
• Are they in the same location or using the same internet provider?
• Is the delay happening on desktop, mobile, or both?
• Are they using Wi-Fi or wired connections?

Your confirmation would be very helpful!

I have checked on Service Health and Microsoft Teams is currently healthy.

In the meantime, kindly try the following suggestions check what could have caused the issue:

• Try Teams in a Web Browser
  • Kindly ask affected users to use Teams in a browser
  • If messages arrive instantly there, the issue is likely with the desktop app or local network settings
• Make sure your firewall or proxy allows Teams traffic as Microsoft’s network requirements are: https://learn.microsoft.com/en-us/microsoftteams/prepare-network
• Collect Teams logs for deeper troubleshooting: https://learn.microsoft.com/en-gb/microsoftteams/log-files
  • 
  • On the desktop app, press Ctrl + Alt + Shift + 1 to download logs
  • These logs can be attached to a support ticket for deeper analysis

Any updates you’re able to share would be really helpful. I appreciate your time and look forward to hearing how things are going!
