Switch tenant in portal.office.com aka make portal accessible by B2B guests
Currently it is not possible to switch the AD tenant in portal.office.com like you can in portal.azure.com.
Without that is is not possible to Access the O365 Admin Panel as an B2B guest account that has Global Admin or EXO/SPO permissions.
Login always takes me to my home tenant with my mailbox.
It is also not possible to do this by PowerShell.
So please make it possible to use portal.office.com Admin Section as an B2B guest otherwise it makes no sense that I can for example assign Exchange Admin permissions to an B2B user.
Mobile app allows quick tenant change but still requires that each user have an account in the local tenant. B2B users are not supported.
Wouldn't it be amazing if all the various Office 365 and Azure portals came together as one, with multi-directory management capability?
portal.azure.com does this so nicely.
As a multi-national enterprise we have been forced to use multiple tenants for various reasons, but our admins are Global Admins from our parent tenant as B2B guests in all the other various tenants. It would make a huge difference to their productivity if they could seamlessly jump around between tenants without needing to manage multiple credentials from each of the different tenants.
i agree to all above!
This is a big problem for me with multiple costumers/tenats,
The mobile app allows the admin to change tenants!

As a partner, sometimes I run into the issue that I can't get back to admin of my own tenant once I've started managing a customers tenant. We need the switch capability that Azure portal has.

We just ran into this issue after converting our admin accounts to b2b/guest users connected to our main Azure tenant. Since b2b users can be made global admin in Azure, it would be beneficial to also be able to make them admin in O365/Exchange/OneDrive/etc.
Even for Partners isn't not perfect.
portal.azure.com gives you a nice list and very easy transitioning between tenants, portal.office.com, even as a partner, sometimes reverts back to the partner tenant and it's not always easy to see which tenant you are looking at. portal.azure.com does this very nicely.

This is huge for us being a parent company of multiple subsidiaries some of which have their own tenants. Our eDiscovery managers and legal staff need to have visibility and access into each tenant at all times. It's cumbersome maintaining a separate set of credentials for each tenant. I know the MPN portal allows partners to switch between customer tenants, it would be nice to have that same capability for B2B customers.

Thanks Peter. Agreed.
We have 3 affiliates that use Office 365/Azure and have had the same experience. For now, we've had to create the tenant.onmicrosoft.com addresses as a workaround... but of course, at that point it's not B2B.
