Question: 2 Company Pages Under 1 O365 Tenant?


Is it possible to create two different Yammer sites for an organisation which has two entities under the same O365 tenant? If not, any potential work arounds?


The organisation has two different companies under an umbrella - however, the branding, messaging etc.. is completely different. Would they be able to access different yammer pages for example with and

Hmm. Might want to check with Support or your Microsoft Account team about this question. I wasn't even aware you could have two orgs in the same M365 tenant.

Your example of and is the default option - each M365 tenant gets Yammer and from an M365 standpoint it is two completely different tenants.

@leighanneenglish It's supported to have only one instance (network) of Yammer associated with each Microsoft 365 tenant. Let's call this a home or canonical network. It is possible to have multiple home or canonical networks associated with your tenant but it's neither recommended nor supported. See this doc; "If you have multiple email domains in your Office 365 tenant and those email domains are spread across two or more Yammer networks, consolidating into one Yammer network is required." So for e.g. if you have two different domains in the same tenant, and, then just like these two domains would be part of the same Azure AD or M365 instance, similarly these two domains should be part of the same Yammer instance. So and would lead you to the same Yammer instance.


This is by design because every M365/AAD tenant is meant to be used for a set of users who are expected  to collaborate freely with each other, across workloads. For e.g. users from can collab with users in using Teams, Outlook, SharePoint etc. So segregating users based on their domain isn't a capability supported in Yammer yet. However, if it helps, you can create Yammer dynamic groups, which can add users to those groups based on the domain in the user's primary SMTP address thereby creating collaboration spaces dedicated for individual domains.


Hope this helps!
