Lost Backup with Microsoft Authenticator
Hello, I lost the phone where I had set up 2FA using Microsoft Authenticator for this email address. I had previously enabled cloud backup and have now tried to restore it to a new phone by carefully following the correct backup and recovery process. However, some very valuable and critical 2FA accounts are still missing and were not restored.
Unable to access Global Admin, username not recognised, need tenant recovery billing active
Unable to access Global Admin account for Microsoft 365 tenant. Username not recognised and I need tenant recovery. Billing is still active. I am the billing owner of a Microsoft 365 Business subscription for yutoriacupuncture.com.au but I have lost access to all Global Admin accounts. The original admin account email is returning “username may be incorrect”. No other admin or business emails are recognised. I have a business email associated with the admin account i can still log into. I recently briefly cancelled and reinstated my domain which may have affected tenant linkage. I also recently joined a university Microsoft 365 organisation which may be affecting sign-in routing? I have tried login.microsoftonline.com, admin.microsoft.com, password resets, and incognito browsers with no success. I have tried contacting support via phone and email but keeps cutting out, saying it can't identity me, or sends me into a loop hole with the support chat bot. I need Microsoft to escalate this to tenant recovery or Data Protection team to restore Global Admin access using billing and domain ownership verification.
Lost Backup with Authenticator App
I recently changed phones and followed Microsoft’s documented process for transferring my Authenticator accounts. Before changing devices, I enabled cloud backup and confirmed that authenticator showed a successful backup dated 21 June. I then installed the app on the new phone, selected the recovery option, and signed in using the same Microsoft account. Both phones used the same operating system, and all required cloud settings were enabled. Despite this, only two of my seven accounts were restored on the new phone. The app on my old phone then stopped working. I disabled VPNs, cleared the cache, confirmed a stable internet connection, checked notification permissions, and ensured battery optimisation was not interfering. When none of this worked, I updated the app. After the update, the remaining account data had disappeared, leaving only the same two accounts restored on the new phone. I followed the correct backup and recovery process. The app confirmed that the backup had completed successfully, yet five of seven accounts were not restored. Is there any way to recover an earlier backup or should I assume that the data I need is lost because of this useless app?mail@mydomain is causing a cert mismatch error in all browsers for Outlook.com
Hello, I have created a CNAME for our users in my domain so that they can access webmail. For example, it's called mail.mycustomdomain.com, and it is directed to Outlook.com But when I try to visit mail.mycustomdomain.com, it shows a security warning and recommends going back. I can understand because the SAN name in the certificate presented by Outlook doesn't include my CNAME. Is there anything I can do as a workaround so our users can enter the CNAME without encountering a Certificate Mismatch Error? It is causing repeated calls to the helpdesk, and we would like them to use something simple they can remember. Thanks

How do I find the account linked to an Office Home & Student 2013 key?
Hello everyone, Microsoft's after-sales service redirected me here because they no longer provide updates for this type of product, nor even security support. I have two Microsoft accounts. However, when I try to reconnect my key to one of them, it tells me the key is already linked to another Microsoft account. But which one?! How can I find that account or regain ownership of my Office key ? Thanks for your help.
Microsoft Authenticator führt Wiederherstellung nicht aus
Ich möchte die App auf meinem neuen Handy weiter nutzen und habe dafür auf dem alten Gerät eine Sicherung erstellt. Wenn ich nun die App auf dem neuen Handy einrichten möchte, bekomme ich eine Fehlermeldung, daß es angeblich keine Sicherung gibt. Ich benötige die App dringend für die MFA. Kann jemand helfen?
Can't access Microsoft Authenticator for business accounts
Hello. I am the tech support for a small church, where I am the admin for our MS 365 accounts, which are set up as "business accounts". I have been using Microsoft Authenticator for MFA for years. Recently I switched to a new phone and installed Microsoft Authenticator. All of my personal Authenticator accounts transferred over just fine, but all of the church's business accounts say "Scan the QR Code provided by your organization to finish recovering this account". The thing is, I am the "organization" and I don't know how to generate any QR code to recover the accounts. It was suggested that I could do something about this by logging into my Microsoft 365 administrator account, but when I try to log into my admin account, the only MFA option is "enter the code from Microsoft Authenticator". It's not offering a text or alternate email, only Microsoft Authenticator, which is what I'm locked out of. So I'm stuck in a loop. I opened a ticket with Microsoft Support nine days ago. I have received one phone call since then. The support person insisted that they needed to talk to the account's "alternate administrator", which I set up as my pastor, who is pretty computer savvy but not a deep IT person. They tried to call him one time, but he was not available to answer right then. There has been no communication since then. I'm hoping someone in this group can help me figure this out.
