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.
Talking to our Partner, it looks like it's not really tenant switching to enable B2B users to be assigned roles and use our o365 portal. Adding a partner & tenant switching gives the partner ability to get global admin and helpdesk admin rights to your tenant (without any PIM intervention), but not utilise "tenant switching" for b2b accounts, like it does in the Azure portal. However, if there is experience otherwise I would be keen to hear. So it's not much use if you want to give your Partner B2B account administrative roles (other than giving them global admin).

B2B works decently if you're a partner but out of luck if you're not. Everything else is moving to portal.azure.com where switching is easy so why not move the admin portal too ?
Is this new feature being rolled out only for the partner of record (Associated Partner) for a Microsoft 365 organization?
As DJ mentioned - is all of a sudden being rolled-out as mentioned in the roadmap article, but only for members of the Partner of Record of the tenant. Actually an access they allready had when using the partner site dashboard.
Looks like it is coming finally.
Unfortunately I don't think Office 365 support team look at Uservoice that's why there has been no updates here.
Is there any update to this? We just got tripped up by this, and haven't seen any documentation around it being unsupported.

How does Azure AD B2B differ from external sharing in SharePoint Online?
OneDrive/SharePoint Online has a separate invitation manager. Support for external sharing in OneDrive/SharePoint Online started before Azure AD developed its support. Over time, OneDrive/SharePoint Online external sharing has accrued several features and many millions of users who use the product's in-built sharing pattern. However, there are some subtle differences between how OneDrive/SharePoint Online external sharing works and how Azure AD B2B collaboration works. You can learn more about OneDrive/SharePoint Online external sharing in External sharing overview. The process generally differs from Azure AD B2B in these ways:
OneDrive/SharePoint Online adds users to the directory after users have redeemed their invitations. So, before redemption, you don't see the user in Azure AD portal. If another site invites a user in the meantime, a new invitation is generated. However, when you use Azure AD B2B collaboration, users are added immediately on invitation so that they show up everywhere.
The redemption experience in OneDrive/SharePoint Online looks different from the experience in Azure AD B2B collaboration. After a user redeems an invitation, the experiences look alike.
Azure AD B2B collaboration invited users can be picked from OneDrive/SharePoint Online sharing dialog boxes. OneDrive/SharePoint Online invited users also show up in Azure AD after they redeem their invitations.
The licensing requirements differ. For each paid Azure AD license, you can let up to 5 guest users access your paid Azure AD features. To learn more about licensing, see Azure AD B2B licensing and "What is an external user?" in the SharePoint Online external sharing overview.
To manage external sharing in OneDrive/SharePoint Online with Azure AD B2B collaboration, set the OneDrive/SharePoint Online external sharing setting to Allow sharing only with the external users that already exist in your organization's directory. Users can go to externally shared sites and pick from external collaborators that the admin has added. The admin can add the external collaborators through the B2B collaboration invitation APIs.
The OneDrive/SharePoint Online external sharing setting
After enabling external sharing, the ability to search for existing guest users in the SharePoint Online (SPO) people picker is OFF by default to match legacy behavior.
You can enable this feature by using the setting 'ShowPeoplePickerSuggestionsForGuestUsers' at the tenant and site collection level. You can set the feature using the Set-SPOTenant and Set-SPOSite cmdlets, which allow members to search all existing guest users in the directory. Changes in the tenant scope do not affect already provisioned SPO sites.
For us too this would be a more than useful feature. We have partner organisations who we need to perform activities within our Office365 portal with their own B2B accounts.
hi, is this something that is still on the roadmap? if so, when might we expect an update?
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.
Valentijn Scholten commented
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.
