problem with presence synchronisation Teams --> 3cx

[Danimannn]

Hello,

I have noticed that for the past few days, the presence synchronization from Teams → 3CX has stopped working. However, the presence synchronization from 3CX → Teams is still working correctly.

I have updated the PBX to the latest version.
I have updated the Windows client to the latest version.
I have "unauthorized" and then "re-authorized" the Teams calendar and presence synchronization.
I have "reconfigured" the M365 integration.

Unfortunately, the issue still persists. Is this a general issue, or is it specific to my system? What else could I try/check to resolve this?

Thanks

Hi @Danimannn

This is not a general issue, we have tried this on our side and it works as it should.
What I would suggest is go into Admin>>Integrations>>M365 and reconfigure the whole integration instead of only presenece.
Additionally you could check the PBX logs to see if the notification from MS arrives at the server.
Just set the system to Verbose logging level and check the 3cxManagementConsole.log.
You should see something like below whenever a status change is made in Teams.

[_3CX.Http] [7]+XX.XX.XX.XX POST https://<FQDN: port>/m365/presence - application/json;+charset=utf-8 2801
[ManagementConsoleJS.Controllers.Microsoft365NotificationsController] Presence notify DoNotDisturb: DoNotDisturb
[ManagementConsoleJS.Controllers.Microsoft365NotificationsController] Set profile to Out of office


If the issue persists after the above, I would suggest that you open a ticket with our support department.

Hi Andreas, thanks for your answer. I just downloaded the LOG file and I see this kind of lines again and again:

I reconfigured the M365 integration again a couple of days ago... I still have exactly the same problem.

The problem with the presence started 2 weeks ago and does not happen all the time, but only sometimes. And the problem is always Teams ---> 3CX. However, 3CX ---> Teams always works correctly.

Ideas?

Thanks.

I've been analyzing logs for a few days now, etc... I've also opened a ticket with 3CX through the partner. It seems that throughout the day there are time intervals of several hours when it works, and time intervals of several hours when it doesn't.

For example, right now the last line I see about presence synchronization in Logs\3cxManagementConsole.log (17:18h) is this one:

2025/04/14 15:25:29.958|0075|Debg| [ManagementConsoleJS.Controllers.Microsoft365NotificationsController] Presence notify Available:Available

This means the instance hasn't synced Teams --> 3CX presence for two hours. During the day, it works for several-hour intervals and then stops working for several-hour intervals. I've been observing this and it happens every day. I've reconfigured the integration (M365) and the presence synchronization (Users/M365) several times over the last few days, but it hasn't improved.

I don't know what else to do. 3CX says they can't do anything, the partner neither, and Microsoft says it's a 3CX issue... it's a loop with no easy way out... I need a competent partner who can help me find the root cause of the problem and its solution. Can you help me with this? Best regards.

I still have the same problem. Can a member of the Support Team/staff help me with the issue?

@Danimannn I've sent you a pm

Was there a resolution to this in the end? We are experiencing the same issue where 3CX > Teams works fine, but the Teams > 3CX side seems to fall over regularly and I have to disable and re-enable the option for "Update presence from Teams clients to 3CX apps" almost daily.

I’m not sure whether it’s due to something I changed on my end or if 3CX or Microsoft made some kind of fix. In any case, I haven’t had any issues for several weeks now – after struggling with the problem for months and trying just about everything imaginable.
Fingers crossed it stays that way. Honestly, I have no idea why it’s working now when it wasn’t before.

Hi everyone, This issue is also happening frequently. After manually reastiblishing the M365 integration, the problem still comes back.
Has anyone found the problem?
