I recently noticed that many Office 365 consumers are facing difficulties in loading Teams when they are using their corporate networks. When they launch Teams desktop app or Teams service on a browser, they are able to successfully authenticate and the above ‘Loading Microsoft Teams’ image appears. After some time, they are presented with the error message: Doh! Something went wrong.

 

Microsoft Teams is based on the consumer version of Skype, not Skype for Business. It makes use of various *.skype.com URLs for loading components, etc. Since most of the corporate networks have blocked *.skype.com domain, Microsoft Teams is not loading even after successful authentication. In this case, IT administrators need to do additional configuration work, such as updating firewall policies, to ensure employees can fully use Microsoft Teams.

 

I really hope Microsoft switches to some other domains so that anyone can use it inside corporate network without any work from their IT teams.

Agreed, this caught us by surprise as well. It also opens up the ability for internal users to connect to consumer Skype which is yet another security hole we have to somehow manage.
Guys, have you checked the Urls and IPs required by Teams? Just FYI: https://techcommunity.microsoft.com/t5/Microsoft-Teams/Teams-URLs-and-IP/td-p/35636
Ok, something changed, but what?

Any "diff" information to pass to one of mine network admin colleagues?
Pradeep:  Actually according to Julie Elmuccio (MSFT) MS Team actually not the consumer version of Skype, but Skype for Business.  See copy of Julie's post bellow. "Microsoft Teams is differentiated from Slack with Office 365 integration (Office documents, SharePoint, OneNote, Planner, and Skype for Business) and Office 365 security and manageability. Additional features that makes Microsoft Teams unique include threaded conversations, the ability to start a spontaneous call in a channel (Meet Now), Tabs which allow teams to customize content by channel and recent activity feed for mobile. IT Admins can manage Microsoft Teams in the same way they manage other Office 365 apps, and can rely on the same security, privacy, transparency and support that comes with Office 365.
This issue is still there or is resolved by now?
You are able to access Microsoft teams or not yet?

Hi @Solange1983 

 

We are always fighting setting firewall rules to enable Office365 functionalities from inside our LAN configuration.

 

We are also discovering configuration limitation in Teams due to users not completly migrated to the cloud (we have Lync/S4B on premise server, Exchange onpremise server)... not easy to coordinate all the innovation in Office365 with our internal infrastructure and policies :(

 

With users completly migrated on O365 (S4B+Exchange) the Teams functionalities are ok, a nightmare in a mixed user configuration.

 

Right now we migrated the affected users and it is working.
