Issue with registering attendance for Tech Community event
While the notification email sent when registering my attendance for a Tech Community event (Windows Office Hours: April 2026 - Microsoft Tech Community) included a calendar invitation, accepting the invitation resulted in me receiving an NDR for the acceptance response (which was sent to email address removed for privacy reasons). These invitations were previously sent from a different email address (of the form firstname.lastname at creatrixmedia.com) and this address happily accepted the meeting responses. Since you don't need the responses, you probably want to update the code creating the .ics attachment to replace RSVP=TRUE with RSVP=FALSE. Hope this is helpful.SolvedRyanSteele-CoVApr 09, 2026Steel Contributor47Views0likes1CommentPosts/Answers not appearing- submitted but not visible to me and other users
Hi together, I've been actively contributing to the Microsoft Sentinel and Microsoft Security discussion categories over the past 3 weeks. My profile counter shows 9 posts, but I can only see one of them in my Recent Discussions list - the other ones are completely inaccessible, not just to other community members, but also to me. I cannot view, edit, or manage them in any way. The posts cover technical practitioner topics and I put significant time and effort into writing these as quality contributions for the community. My concern is that I have no way to tell what happened to these posts. There were no notifications about rejection, no indication that they're pending moderation, and no way to check their status. They simply don't appear anywhere except as a number on my profile. I completely understand the need for content moderation, especially for newer accounts. But without any feedback mechanism, I'm unable to determine whether I should wait, resubmit, or change something about how I'm posting. Could someone from the community team look into my account and help me understand what's going on with these missing posts? I'd really appreciate any guidance so I can continue contributing. Thank you!SolvedMarcel_GraewerApr 06, 2026Brass Contributor61Views0likes2Comments
Why is the memory manager in Windows version 1703 faster than the current Windows versions?
I tested the speed of programs in Windows version 1703 compared to the current versions, I made sure no anti virus or other background processes where interfering. Geekbench scores 13% higher in multi core tests compared to the latest Windows. When testing pure CPU performance there is no difference but memory intensive programs suffer about 10..15% in the latest Windows compared to 1703. Test were run on an 8th gen Intel i7 with spectre and meltdown mitigations disabled. Does anyone know what changed in the Windows memory manager since version 1703 and is it possible to undo these changes?SolveddzjorritApr 02, 2026Copper Contributor70Views0likes2Comments
MFA reset needed - lost phone and access to account with it
Hi! I am a single-tenant MS 365 account (business) and I lost my phone and cannot access my account any more. I cannot log into my account (because I need my Authenticator) and I cannot set up the Authenticator (because I need to log into my account for that) and I am desperate for a solution as this is my business account and has everything I need to keep my business going. I lost access on March 2, had access to Outlook on my browser until early morning on March 4 when I completely lost access to everything. What I do have: the phone number that is attached to this account (it is supposed to be one of the sign on methods, but the system won't let me use it) the password (also not able to use it to log in) the email domain is also mine, I can prove ownership I have the last invoice for the account subscription and can also provide the billing information as well as the card number that is attached to this account for automatic billing I am still using the same main device (laptop) that I have been using since the account was set up I am the only employee and the legally authorized representative for the company that the account is for (and the company name is on the invoice as well as the tenant name) You can also see that there have been no successful logins since I lost access where the account was used almost every day since it was set up (including some weekends), also proving that I am the user for the account. I am currently using my old Microsoft account to contact Support via chat but they are telling me a different thing each time we talk, I have literally submitted tickets/contacted 5 different departments/systems and just keep being ping-ponged around and the Support number that I found is asking for an 8-digit code which I guess is also the Authenticator code that I cannot get as I lost access to my old Authenticator so now I have no idea how to proceed. Tickets that I can track: SIR22967120 - I just received a notification that this has been closed because this was not the correct place to raise this YQN2RK7D - no response yet SGBQ7U9T - no response yet 4766105c-db53-40b3-92b8-ddd8c7968a0d - only the auto-reply that request was received an 1 email saying that the provided email address was not found in their system, I followed up with additional details in several emails but no further response or confirmation that anything has been received. I also sent an email to mailto:email address removed for privacy reasonsbut no response there as well I am ready to send any information/documentation to prove that the account is mine, please let me know how to proceed. I am really desperate for a solution here - this is my business account and everything I need is there - my email with all my contacts, the pending deliverables to clients, my working files, etc. This is week 3 already and I haven't had anyone ask me for any proof of ownership, documentation or anything, I don't know what to do to understand if anyone is even investigating anything regarding this, please help. Looking forward to any suggestions!SolvedStraumeMar 16, 2026Copper Contributor169Views0likes1CommentGetting to the right page to "Start a discussion"
Seeing some confusion about how to get to the right page for a Community where you can start a new discussion. e.g. Where / How to find "Ask a question" | Microsoft Community Hub Office outlook 365 .. where are emails saved? | Microsoft Community Hub I have to admit that it is not clear to me what the difference between these links is. Community Lounge | Microsoft Community Hub Tech Community Discussion | Microsoft Community Hub Why only one has "Start a discussion"? Why does a Web Search tend to land me on the one that doesn't have "Start a discussion"? Why the "Discussion Spaces" button on the one with no "Start a discussion" doesn't make "Start a discussion" appear or take me to the URL that does have "Start a discussion"?SolvedHornblower409Mar 02, 2026Iron Contributor124Views0likes2Comments
Email hacked - I lost total access
Hi community, I had my email hacked 7 days ago, the hacker changed the password. The problem is that I have microsoft office 365 in that account and I tried every single way to recover my access. Even the ACSR, forms and everything. Nothing works. I got replied back that information provided was insufficient. The problem also is that I created this account in hotmail, maybe 20 year ago. Does anyone know any how to contact Microsoft support? How can I find a channel to support me? Thanks in advance for any clue you might give me to solve this issue.SolvedfiandradeMar 02, 2026Copper Contributor77Views0likes2CommentsCan not use URL https://support.microsoft.com ?

Entra ID hacked
Dear Community, I am seeking urgent guidance regarding a serious security incident involving my Entra ID tenant. My tenant was compromised, and the attacker removed my Owner permissions from the Tenant Root Group and created two high-spec virtual machines without authorization. This resulted in approximately USD 9,500 in unexpected usage charges. I immediately blocked my credit card, and the subscription has now moved into a disabled state, most likely due to non-payment. However, I am still unable to regain administrative control. I previously managed to open a support ticket using another account, but it was limited to subscription-related issues only. Even when the case was marked with Severity A, Microsoft support was unable to treat it as an urgent incident or take immediate corrective action. At this point: • I only have read-only access • I cannot create a technical support request • I cannot upgrade the support plan • I cannot restore Owner permissions • I am unable to properly escalate the compromise If anyone has experienced a similar situation or knows the fastest way to: • Regain Tenant Root Group ownership • Reach Microsoft security team for compromised tenant cases • Escalate beyond standard support channels I would truly appreciate your advice. This has been extremely stressful, and I am trying to regain control and prevent any further damage. Thank you in advance for your support.Solved201Views1like1CommentWhy do you allow simple user questions in TechCommunity that should be in Q&A?
I see numerous post of simple user questions that would be more appropriate for Q&A. e.g. more outlook BS ! | Microsoft Community Hub Unable to send emails to outlook | Microsoft Community Hub Large, ANNOYING FONTS when composing a New Message | Microsoft Community Hub As the Outlook | Microsoft Community Hub banner says: This is the place to discuss best practices, news, and the latest trends and topics related to Outlook.SolvedHornblower409Feb 10, 2026Iron Contributor187Views1like3Comments
