Hello,
You can follow those steps or the ones by images and text here – https://jorgedelacruz.uk/2022/03/21/veeam-how-to-enable-multi-tenant-on-the-new-restore-portal-on-veeam-backup-for-microsoft-365-v6/

You will still need to auth on the different tenants to enable the self-service. And I am sure this other blog post could be useful too, in case you want to offer to your tenants something like https://portal.theirowndomain.com instead of your generic URL – https://jorgedelacruz.uk/2022/03/24/veeam-how-to-add-new-urls-to-be-able-to-login-on-the-new-restore-portal-from-veeam-backup-for-microsoft-365-v6/

Good luck!

Hello,
Well, the URL should be an FQDN right? like https://myvbserver.domain.co.uk:4443 which resolves to an IP. The external devices should use a DNS that tells them exactly that, that FQDN resolves to an IP, in the case that you are utside your network could be resolving to 80.90.40.70 or whatever public IP you have for that server, and you should be doing NAT of the port 4443 on your Router/Firewall. Besides that, well the usual Windows Firewall on the machine.

Thanks for these tips it has been a great help in getting the self-service portal enabled. However, I am unable to access the portal URL on any device other than the server with the rest api on. Any tips on how to get this working would be appreciated.

Thanks!

Hello,
I’ve covered those steps in another blog post, but to find the entire list of articles, which includes SSL, adding additional URLs, etc. Please take a look here – https://community.veeam.com/discussion-boards-66/vb365-a-collection-of-fines-herbes-2430

Thank you so much; please do not hesitate to ping me with any questions you might have.

I have really enjoyed reading a few of your blogs, we are a Veeam service provider and provide 365 BaaS, and I am in the process of investigating configuring the self-service portal after I’ve recently upgraded it to version 6a. However, I am looking at the section of enabling the Restore Portal in the General Options, and I am unsure of who’s account I should be using to authenticate with Microsoft 365, as obviously, we have multiple tenants including our own tenancy. I’ve authenticated it with our GA account for our own tenancy, but how does this work with multi-tenancy?

I look forward to hearing your reply.

Kind regards

Stacey

Good afternoon Caroline,
So, I have been messing around and found a few “hacks” to edit the logos, and some colors, but as said there are really hacks that I am assuming they will not be supported officially by Veeam.

Let me ask!

Thanks for reading, and commenting as well.

Best regards from Germany,
Caroline
