51 TopicsI need to speak to a person at Microsoft
Firstly, I don't know if this is the correct place to ask, if not, I apologise, and would be greratful if I could be directed to the correct medium. So..... *** I am writing this on behalf of someone else *** His account has been locked after he had been hacked and infected with a virus, and Microsoft will not unlock it. However, they have decided (today) to take his money for his 365 subscription, that he can't use, and doesn't want. When looking for a way to cancel it, the answer is log-in to his account and cancel it himself. BUT, he can't log in because the account is locked. He has tried looking for a phone number to speak to someone, but cannot find any. He has tried looking for a Live Chat, but, (if it exists) it is only available after he logs in. He just wants to cancel the subscription, and get a refund. Can someone please give me a contact number - preferably in the UK, but any English speaking representitive, in any countrty will do. Thanks,26Views0likes1CommentSecurity Admin Center Tenant Allow/Block List Not Able to Block IPv4?
While using the Security Admin Center Tenant Allow/Block List we have been able to block specific email addresses and IPv6 IP addresses but are unable to block IPv4 IP addresses. We have tried both using the console and the CLI but have turned up unsuccessful both times when it comes to IPv4. A large majority of the phishing attempts that we encounter come from IPv4 addresses but we have been unable to block any of these. Will there ever be functionality for IPv4 within the Tenant Allow/Block list or is the only option to use conditional access policies? Also why is this enterprise tool only functional with IPv6 and without documentation stating that it does not work for IPv4?1KViews3likes4CommentsNot able to logon office 365 account or change it

Hello all, I’d appreciate some guidance from the community on a serious situation we are facing. On 12 September 2025, our Microsoft partner unilaterally locked us out of our Microsoft 365 tenant. They retained exclusive Global Administrator / Partner Delegated Admin rights, which means: All staff and directors are unable to access email, Teams, SharePoint/OneDrive, or even log into their Azure AD-authenticated workstations. Our corporate and staff personal data is now inaccessible to us as the controller. Access restoration has been explicitly conditioned on payment of a disputed invoice (not related to Microsoft licence pass-through). This raises several concerns: Operational: we are effectively paralysed. Security/IP: the partner still has exclusive access to proprietary source code and other confidential business data. Compliance: we cannot meet our GDPR/UK DPA obligations on availability of personal data while locked out. We contacted Microsoft Business Conduct on Friday evening with full details of the incident, but so far no human response has been received to those emails. Questions for the community From a Microsoft tenancy perspective – what’s the fastest/most effective way to remove a partner’s delegated admin access if they refuse to release it voluntarily? Has anyone experienced or seen a similar scenario where access was conditioned on disputed payments? Are there formal Microsoft Partner Code of Conduct provisions that directly address this type of misuse of delegated admin rights? Any practical lessons on balancing the technical fix (regaining control of the tenant) with the legal approach (injunction, regulatory notifications)? My focus is on regaining secure access, protecting data/IP, and ensuring compliance. Any experience, insight, or links to Microsoft policy/resources would be greatly appreciated.88Views0likes1CommentUnable to whitelist quarantined emails
We have an email that is being constantly quarantined from a webform. The email comes from the email of the web form server, but is spoofing an internal address in our tenant by design. The email keeps getting blocked, and nothing we've tried as far as transport rules, whitelist additions, etc has been able to discernably affect this. There is a option to create a tenant allow list entry but the maximum duration is 45 days. We need a way to reliably whitelist an email indefinitely.98Views0likes1CommentChange default recipient for default security alerts
In the Office 365 Security admin center, under Alerts > Alert policies, all of Microsoft's default alert policies are configured to send to "TenantAdmins". I would like to change this default recipient address for all existing and future default alerts, without having to manually change it on each alert. I have found that you cannot modify these alerts using PowerShell. But is there a way to set the default recipient for default alerts? I haven't been able to find one.Solved15KViews0likes3CommentsAdding Outlook add-ins and permissions
Wonderoig if someone can answer a question for me. I'll use the process in this link as context https://help.draftable.com/hc/en-us/articles/46382047949977-Configuring-Redline-in-Email-Outlook-with-Draftable In short when adding an Outlook Addin and selecting a group to assign the add-in too and the accepting the permission requests does this: Apply the permissions to ONLY those nominated users' mailboxes; or Applies the permissions to ALL mailboxes and applies "security" by limiting the users who can see the add-in I assume it does one of the two. Any ideas?142Views0likes2CommentsInterface Views in Microsoft 365 Admin Center

This happens a lot. I get these emails from Office365Alerts notifying our team that "A medium-severity alert has been triggered". At the bottom of the email is a link to "View alert details". When I click that, the site shows an error: "Can't find it. Either what you are looking for doesn't exist or you need to use a different search string." So, then I go to the Alerts view and filter to show everything (at least I think I am) but there's nothing related to this particular alert (unusual volume of file sharing). Where did it go? EDIT: Including a screenshot of another email I got today. The result of clicking the 'View alert details' is again the same.20KViews3likes23Comments
