Hi,

Our domain is hosted on the Office 365 (rayat.com) and got configured the DNS as requested on the admin portal.

We are communicating with other organizations on the Office 365 with no issues.

However, when I'm trying to add someone from Microsoft employees, or other organizations that are not hosted with Office 365 the users remain in the "unknown" status

Sample of the other domains is (riyahdschools.edu.sa) where I contacted their admins and he confirms the publishing and settings are configured correctly.

But I'm still wondering why I cannot communicate with MS employees!!!!

Any idea?

In Office 365 SfB Admin portal configure external access as "On Except for blocked domains".               

Thanks,

That already done, and basically after we did that we were able to communicate with other domains on Office 365

Yet, I don't get it why I'm unable to communicate with MS team or RiyadhSchools.edu.sa users!

Any other suggestions?

HI

Could be the reason you Domain Rayat.com is not added in their federation list. You always require to add domain name in the federation list in the Lync control panel from both  side, weather it is on-prem/online.

Hope this clarifies.

Well, that doesn't make sense!

Do I need to add every domain to the list for my users to be able to connect with other organizations?

Even worse, I need to communicate with other organizations and ask them to list our domain(s) in their Lync servers!

As I understood, it's enough to enable the option "<label for="cbxAllowSharing" style="width:auto;">Let people in your organization use Skype for Business to contact people in other organizations" to get in touch with other organizations</label>

Unless you're pointing to something else, I don't think this is the issue.
