Teams only - unable to communicate with external Skype for Business users
RichLewis Only if the data is getting there the same for each org, 9 times out of 10 this type of issue is related to a client's firewall not passing traffic as expected, particularly since in your explanation was there was asymmetry happening
StevenC365 I am getting the same issue from multiple networks (even public ones with now firewall to consider). Doesn't this suggest a configuration issue with source org 1?
RichLewis It's incredibly unlikely there is an issue with Teams, it's a shared service with millions of customers, you will be getting the same service as anyone else. There isn't anything that you can configure either. Raise a ticket with Microsoft but I am incredibly doubtful there will be issues anywhere other than in SfB On Premises configurations and Firewalls.
- Thanks for your input. This issue has now been resolved. The S4B destination had a specific edge server defined in their allowed federation list. Removal of this, leaving just the allowed domain fixed the issue.
