Sole Global Admin locked out - lost MFA device, SSPR phone verification returns error
Hello, I am the sole Global Administrator of a Microsoft 365 Business Standard tenant and I am completely locked out of the account. What happened: - My phone with Microsoft Authenticator was physically destroyed. - I installed Authenticator on a new phone. My personal account restored from cloud backup, but the work account only appears as a "connected account" - it shows no TOTP code and receives no push notifications. Push requests still go to the old device. What I tried while my admin session was still alive: - Entra ID > per-user MFA > "Require selected users to provide contact methods again" - saved successfully. - User > Authentication methods > "Require re-register multifactor authentication" - returned "Delete operation failed. Try this command again or delete them one by one in the user authentication methods blade." - The Authentication methods list for the user was EMPTY, and default sign-in method showed "No default". "Add authentication method" button was greyed out. - "Revoke sessions" - succeeded, but this also terminated my own admin session and signed me out of Outlook and OneDrive. - aka.ms/mfasetup cannot be reached because it requires a fresh MFA challenge. Self-service password reset (passwordreset.microsoftonline.com): - First verification via alternate email succeeds every time (I have full access to that mailbox). - Second verification fails: both "Text my mobile phone" and "Call my office phone" return "Sorry, we ran into a problem contacting you." I tried +370xxxxxxx, 370xxxxxxx and 8xxxxxxxx formats - same error every time. This looks like a service-side failure, not a formatting issue. - Sign-in Helper now also reports "Account blocked due to multiple incorrect password attempts." Error codes seen: 500121 and AADSTS50133. I have tried calling Microsoft support in several countries. The automated system either asks for an internal extension number or the AI assistant disconnects the call before reaching a human. There is no second Global Admin and no recovery codes. I can provide the tenant ID, user unique identifier, subscription order number and proof of access to the billing email address privately. Requesting escalation to the Data Protection team for admin account recovery. Any guidance on how to reach a human agent would be greatly appreciated. Thank you.
Excel Desktop Filter Checkboxes Not Visible – Windows 11 / Office Home & Student 2021
Excel Desktop Filter Checkboxes Not Visible – Windows 11 / Office Home & Student 2021 I am facing a persistent display/rendering issue in the Excel desktop application when using filters. When I apply a filter to a column, the filter dropdown opens correctly and the values are displayed. The filter functionality itself also works. However, the checkboxes beside the individual values are not visible properly. As shown in the attached screenshot, the values such as 11, 12, 22, and 34 are displayed in the filter list, but the checkbox controls beside them are either missing/not rendered correctly. Interestingly, the Select All checkbox area also appears abnormal. System details Operating System: Windows 11 Microsoft Office: Home & Student 2021 Application: Microsoft Excel Desktop Office is fully updated with the latest available updates. The same Excel file works correctly in Excel for the Web, where all filter checkboxes are displayed normally. Troubleshooting already performed by Microsoft Support Microsoft Support has already remotely checked the system and tried several troubleshooting steps, including: Reinstalling Microsoft Office Creating/modifying relevant Windows Registry entries Creating system restore/checkpoints during troubleshooting Creating and testing with a new Windows user profile Checking and installing all available Office updates Unfortunately, the issue still persists. Since the problem does not occur in Excel for the Web, it appears to be specific to the Excel desktop application's UI/rendering on my Windows 11 system. Has anyone experienced a similar issue with filter dropdown checkboxes not rendering or appearing invisible in Excel Desktop? Could this be related to: Excel hardware graphics acceleration/rendering Windows display scaling or DPI settings GPU/display drivers Office 2021 UI rendering Windows 11 accessibility/display settings A known Excel Desktop bug Any suggestions, known fixes, or confirmation of a similar issue would be appreciated. Screenshot attached for reference.

Bookings 2026, Cannot Find or Edit "Staff" Configs
Whenever a staff member goes to bookings, they can share their 15- and 30-minute times, but they do not see Staff or anything on the left side of the window like if the menus were available. I am a global admin and even I don't see those left pane options. We made a user the Virtual Visits Admin and they also don't see those options. So how do we get Bookings to consider other calendar appointments already in place so there is no double booking? There is also not a three lines icon to open the pane to see the left side menus.
Unable to Access Admin Center - SMS and Authenticator Options Not Working for Account Recovery
I am currently unable to access the Microsoft 365 admin center because I cannot complete the account verification process. When I try to loggin to my account, the assistant only offers two options: using the Microsoft Authenticator app or receiving an SMS code. Unfortunately, I do not have access to the Authenticator app, and the system is not able to send me the SMS code either. This leaves me completely locked out of the admin panel. I have tried multiple times to use the SMS option, but I never receive the code. The recovery assistant keeps prompting me to use either the Authenticator or SMS, but neither method works. Because of this, I cannot regain access to the admin center. I have the correct password, but without multi-factor authentication (Authenticator or SMS recovery) I cannot access the Microsoft 365 admin center. Without access to the admin center, I cannot create or manage support requests directly from the admin portal. I also tried calling support by phone, but the AI does not understand what I am saying and does not transfer me to a human agent who can actually help me resolve the problem. I would appreciate any guidance on how to contact so a human for support or alternative ways to verify my identity and regain access to the Microsoft 365 admin portal. Thank you in advance for your help.Stuck in an authenticator loop
I have a 365 Business account. Haven't logged in for a while due to reasons, i was just starting up as a sole trader. Anyway decided now is the time to resurrect it and get up and running, except Authenticator doesn't work because I changed my phone, and my back up email is out of date, and no longer exists. I have tried the support web chat which wants to send a code to authenticator or my back up email. Just called the help line that referred me to the web chat which doesn't work, I couldn't get past the bot. So I am stuck. Any recovery options does not recognise my log in details, i think this is because its been a while since I logged in (I still pay but ....) but I can't resurrect it because I don't have a way of getting a code due to authenticator/back up email as cited above. I am really at a loss as to what to do. I don't want to abandon it and start again as there are documents in my one drive that I need. Can anyone help please. (I think all that needs to happen is an update to my back up email and then I can get going). I am the sole administrator on my business account.Microsoft Teams and Authenticator lockdown
I’m having a very frustrating issue with Microsoft Teams. I am able to log in to teams using my normal personal email and account ONLY ON THE WEB BROWSER. From the web browser, I am not able to access the business channel that I am in. When attempting to log in on the downloaded mobile Teams App, I am sent directly to Microsoft Authenticator, which after waiting several hours, waiting even a full day, is still displaying a message about repeated verification attempt and to wait and try again later. I have accessed Microsoft support chat and they had no help for me. I need the authenticator lockdown to refresh and it will not.
