M365 Sync not working as expected

[Christian klarer]

Hi there
Since a while (I believe since an update, but not sure) the M365 sync isn,t working properly. Bevore it was pretty much a realtime sync, now it takes an undefined amount of time to sync a contact from M365.
It did when I openened the setting but not on it's own. Any suggestions on this?



My PBX:
18.0 (Build 461)
On Premise
Professional Annual

Microsoft should notify 3CX instantly of any change, through the redirect URI. Please check if the HTTPS port of 3CX is open on your network firewall.

You can easily do this by going to the messaging page of 3CX, click on Add Facebook (I know I know, not relevant to MS 365 integration) and click TEST. You do not need to configure facebook, just use the test button. If it is successful, you can just cancel the configuration of the messaging.

If it is unsuccessful, you will need to configure the HTTPS port to come on to the PBX successfully.

Even if 3CX cannot be updated real time, every 24 hours, in the early morning hours, 3CX will go and update everything from MS.

Ok Thanks
Works fine. Customer said the next day the changes where there.
They think about changing to crm contacts but their crm only supports tapi. Any hints when the client v16 will be depreciated?

Thanks
