When using proxy on localhost teams fails to establish TCP connection for login
This is a strange problem, and it took us quite a while to get to the bottom of it. We tested on Windows 10 and Windows 11 with the latest Teams app. What is the problem? We are working on a solution the monitors network traffic for a safe school environment. As part of that we install a local proxy on Windows devices. The proxy is configured as manual proxy in the proxy settings. When requesting to sign into Teams, Teams establishes a connection to `login.microsoftonline.com`. Without the proxy that works without problems. Teams establishes a TCP connection, sends a CONNECT, TLS handshake and then encrypted data. When activating the local proxy any connection is fine (e.g. `teams.events.data.microsoft.com`, `nav.smartscreen.microsoft.com` are established just fine), but the one to `login.microsoftonline.com` is not established. In Teams this results in an error page that the login page can't be reached (it reports a 404, but it's not a 404). We ensured that nothing was blocked and there are no lower level connection errors, then we dug deeper with Wireshark. Once accessing the login page (which would trigger connection making for `login.microsoftonline.com`) we see a `SYN` being sent to establish the TCP connection, but there is never a `SYN/ACK`. The local proxy never receives this `SYN` (no connection is ever established), somehow it never reaches the destination but is "dropped". We can see that Teams tries to re-transmit the SYN, but it never arrives at the destination. A tcp `SYN` not reaching it's destination points to it being blocked somewhere, so we: - Turned the firewall off (anything that can be turned off is turned off) - Added specific allow rules for any other device control that could block. This did not help, the problem keeps persisting. (Note: We were able to reproduce this problem with a different proxy solution as well. Once we configure the proxy on localhost we run into this issue.) We also tried: - Configure the local proxy with the IP address of the machine within the local network (i.e. 10.12.128.2) instead of `127.0.0.1`: Leads to the same problem. - Run the local proxy on another Windows machine, turn off firewall and connect to the proxy on the other machine: No problems with this solution, the connection is established fine. We then tried to configure the proxy via PAC file (without a DIRECT fallback), which result in different weird behavior. In the browser the behavior is as expected - pages that are blocked by the proxy report a connection failure, pages that are allowed can be accessed. For Teams login we don't run into problems with the PAC file based settings, but Teams does not route the connection to `login.microsoftonline.com` through the proxy! The connection to `login.microsoftline.com` somehow implicitly bypasses the system wide proxy settings when using a PAC file (i.e. I see the connection in Wireshark, but it's directly established, not going through the proxy even though it is configured via PAC file). Other connections related to Teams are established through the proxy as expected. I don't think this is expected behavior. I have Wireshark traces that show all the different behaviors. If needed I'm happy to add them to this ticket. It would be great to get help with a better understanding what could be the problem. What could cause this behavior (in Teams / in Windows)? With a better understanding of the behavior we could work on overcoming this problem.
Outlook plugin: Updating manifest doesn't work, Update TenantAppDefinition failed
Hello, I raised this request to the official MS customer service already and they couldn't help. The problem is as follows: We are developing an Outlook Add-In using the 'new' JSON manifest way. So far, we deployed our plugin to the Azure BLOB storage destination as it's specified by Teams Toolkit. Also, we were able to register it in the MS Teams Admin Center. Now we wanted to make some changes to our icons registration in the manifest file and ran into an unknown exception. For testing, we reverted those changes and only increased the version number. However, the error message remained as-is, although the same manifest worked some time (maybe 1-2 weeks maybe) ago. There were no changes to the manifest file since then, except an increase in the version number. The manifest can be submitted without any issues if the "ribbons" part is completely removed. However, it passes all validations described in https://learn.microsoft.com/en-us/office/dev/add-ins/testing/troubleshoot-manifest . All icons match the specifications. The same happens if we submit it as a new app. This is the error message that we could intercept in the browser's DEV Tools when submitting the manifest in the appPackage to MS Teams Admin Center (manage existing app). Sensitive info was removed: { "error": { "code": "BadRequest", "message": "Update TenantAppDefinition failed, UserId: 'beefbeef-beef-beef-beef-beefbeefbeef', TenantId:

Monitoring of SBC
Hello Hope you have great time. Microsoft provides Power BI's QER PS v1.0.pbit QER v5.0.pbit These are good Power BI's that help monitor health of SBC's. Which metric within would you use to monitor the SBC. If one SBC is down and the configuration on Power BI Service is to alarm you than how can you avoid to get the repeated alarm of the same incident. Is it also possible to monitor there the expiration of certificates Regards JFM_12
Need Information on Microsoft Teams O365 Management API
Hi Community, I was exploring the Office 365 Management Activity API documentation- https://learn.microsoft.com/en-us/office/office-365-management-api/office-365-management-activity-api-reference and came across a few queries. I hope someone can help clarify these: Maximum Volume of Data: What is the maximum volume of data (e.g., MB/GB per day) that we can retrieve using the Office 365 Management API for Microsoft Teams? Is there any specific limit documented? Filtering Logs by Workload: When sending requests to the Office 365 Management API, how can I fetch logs specific to Microsoft Teams? I tried applying the filter Workload: MicrosoftTeams in the request, but it also returned logs for other workloads. Below is the API URL I used for the request: https://manage.office.com/api/v1.0/<TENANT-ID>/activity/feed/audit/<contentID> I checked the documentation but couldn’t find specific guidance on these points. Can anyone provide insights or share examples of how to resolve these issues? Thank you in advance!Teams or security groups should be searchable in the search field
Hello , Our users that we are connected to have stated that not being able to search for Teams teams or dl/sg causes a waste of time and that they meet this need on the Outlook side. In a similar way as in Outlook, searching for teams or groups will provide a mini window and displaying the features of members etc. will save time and be beneficial for users.MS Teams Connector pop-up not loading and more
Hi there, I have several issues with the MS Teams Connectors at the moment: 1. Connectors configuration tab not loading in the web app. I get the message that teams seems to be offline, which is not the case. I tested it in the mac desktop app and there it works fine: 2. The outlook connector configuration page is not working (already reported in https://techcommunity.microsoft.com/t5/teams-developer/issues-with-ms-teams-connectors/m-p/4195335) -> https://outlook.office.com/connectors/publish redirects to https://outlook.office.com/connectors/connectors/Home/Error 3. A few days ago, once I configure my connector (I am using our company "awork" connector) and you click on the Save button, the microsoftTeams.settings.registerOnSaveHandler gets executed as expected, however the connector is not saved. Now it doesn't even let me open the configuration page anymore. No changes were done by me in the meantime. The request id is 00-cd956e28829c4e89f03f9b76677ea30b-b8e156a867f6a66b-00 The integration is important to us as this affects several of our enterprise customers. Is there any other info I can provide? As the connectors are not deprecated yet, I would expect this whole setup to still work... Kind regards Ian
Question about "Open" button on the "About" of Teams Android mobile
Dear Sir Unlike iOS mobile, I found "About" tab on Teams Android mobile. I works well. However, there is an "Open" button at the bottom side. I'm still developing my Teams app. So I'm testing the app by locally upload. The "Open" button of My app is not activated. Other app installed from Teams Store has the button activated below. Do I have to set/configure to activate this "Open" button on the About? Otherwise, is it related to Teams Store production. Many thanks BH
Connector Compatibility Issues with Updated Microsoft Teams
Hi, We have been successfully using our app connector for several years without issues. However, since upgrading to the latest version of Microsoft Teams, we have encountered significant functionality problems that were not present in the older version. While the connector continues to work flawlessly on the older version of MS Teams, it fails to configure or remove connectors in the new MS Teams. Additionally, the webhook functionality is also non-operational. We have noticed missing context values such as 'teamName' and 'teamId', which may be contributing to these issues. I have attached screenshots below for your review. Old MS Teams context New MS Teams context Furthermore, we are experiencing problems with the microsoftTeams.settings.setSettings() function from the Deleted/teams-js library, which does not seem to operate correctly in the new MS Teams environment. It is unclear whether this issue is related to the saveEvent.notifySuccess() function or if there are other underlying problems preventing the settings from being applied properly. Many of our clients are expressing their frustration due to these disruptions. We are eager for your assistance and look forward to your swift response to help resolve these issues. Best regards,
