Hi,

 

Ever since GA we've been unable to use IE on corporate desktops to access Teams:

"D'oh! To open the web app, you need to change your browser settings to enable DOM storage.​​​​​​"

 

Enable Dom Storage is ticked under Advanced - Security

 

Win 7

IE 11.0.9600.18537

 

Chrome works fine.

 

Anyone any ideas before I try support?

 

Cheers.

Turned out to be a change required to Trusted Sites post GA.  teams.microsoft.com.

 

Have asked for a defninitive list of the MS URLs that must be Trusted.  Still waiting...  Initial response was to add all 365 URLs, for which we know to be incorrect/overkill.

It's not so much that the pages need to be trusted, but if you have your ADFS or other auth service in trusted sites then lots of components will need to be trusted too.

Teams works just fine on my home machine that trusts nothing, but at work it needs to be trusted as ADFS is trusted.

It's more to do with which zones can share auth, that'll be coockies I guess.

External access doesn't matter so much as ADFS would normally just be in your internet zone.

For corp computers ADFS would be in INTRANET, Internet would normally be running in protected mode, so you have to add a subset of O365 URLs to Trusted in order to share auth.

 

The URL guidance from MS is not great - Finding more sites need to be trusted that are not documented on the URL/IP pages.
