Multi tenant implementation - Dynamics 365 for Sales

(0) ShareShare

Posted on by SergioBap 15

Hi all, maybe some of you would have an advice for me.

I have a customer (Customer A) who acquired another company (Customer B) and wants them to use the same Dynamics365 for Sales solution that Company A already uses.

Company B has a different Office 365 Tenant.

I can setup more users of Company A tenant for all Company B users but they will not be able to use the Outlook App has their mailboxes. How would you recommend to set this up, knowing that my goal is that all users use their own accounts and are able to use app for outllook and contribute to the same instance of Dynamics 365?

Thanks in advance for all the contribution to figure this out as I cannot see a solution to do this.

    If for some reason Company B needs to keep their users in that tenant with that domain, then the only option I can think of is using Azure Business to Business accounts.  This would allow Company A to invite users from Company B to collaborate with Company A's Dynamics 365 environment.  Here is an link that explains more:

    Hi Efrain, thanks for the help. Unfortunately I had been at that link before and other documentation about B2B Collaboration and I always stumble at the same difficulties: any email activity is not supported. Such as using the Dynamics App for Outlook. So the result is not satisfatory. People could use the their own credentials to log in (which is already a good thing) but could not use email activities or the app for outlook, which, in my case is mandatory.
