Replying to emails from M365 Outlook group
A problem I am stumped with, so I am reaching out for some help/guidance. One group wants to not have the emails going into their own inbox but manage and reply only from the group inbox itself (so they know the email has been processed by deleting it once replied). It worked OK to begin with and then some users couldn't reply, then more. Some still can. I have tried reindexing local copy, using browser instead of app & changing the send on behalf of permissions. Owner or member of group doesn't seem to make a difference. Error messages include "This message can't be sent because it no longer exists. It can only be discarded. Make sure you copy the contents of the message before you discard if you want to use them later." and "Couldn't send this message". Please see screenshots attached. My questions: 1: Is Outlook on M365 designed to allow users to reply from the group either as the "group" or as themselves? Information I found isn't clear. 2: If it is / can be - what can I do to make it work for all users? Thanks!
Office 365 Problems
Hello everyone, I have been experiencing the following problem since today: As soon as I try to open Excel, Word, Outlook, etc., they close again immediately. Online repair and reinstallation did not improve the situation. Some of my colleagues are experiencing the same problem. Background: We roll out updates at intervals. The users who were in the first interval are experiencing these problems. The update interval has been stopped, but unfortunately I can no longer undo the update. The following version is displayed: Version 2509 Build 16.0.19231.20138. The computers are running Windows 11 with the 24H2 update. Does anyone have the same problem or know a solution? Thanks in advance.

OneDrive vs SharePoint
In the world of Microsoft 365, both OneDrive and SharePoint serve as robust platforms for file storage and collaboration. Yet, understanding which one fits your specific needs can be challenging. This blog explores their key differences, practical use cases, and offers guidance to help you make the right choice. What Is OneDrive? OneDrive for Business functions as a user-specific cloud repository within the Microsoft 365 framework, optimized for individual file storage, synchronization, and personal document management. What Is SharePoint? SharePoint Online operates as a collaborative content management and intranet platform within Microsoft 365, engineered for structured data handling, enterprise-level document sharing, and workflow automation across teams and departments.
Best Practices for Sharing Community Updates with Microsoft 365
Hello, I manage an online community and use Microsoft 365 to keep members informed by posting announcements in Teams, storing patch notes and FAQs on SharePoint, and automating alerts with Power Automate. This workflow worked well for our latest update (shared on [https://nullsbrawl.tech/](https://nullsbrawl.tech/)), but I’d appreciate suggestions on improving SharePoint design for better engagement, automating updates more efficiently, and tracking which members read the announcements.
Inquiry Regarding Microsoft 365 E5 Developer Subscription Renewal
Dear Microsoft Support, I hope this message finds you well. I am a developer currently enrolled in the Microsoft 365 E5 Developer Subscription program. Recently, I noticed that my subscription has not been automatically renewed, and I am unsure why this has occurred. Could you please clarify whether the Microsoft 365 E5 Developer plan is still available? If it is, I would appreciate your assistance in investigating why my subscription was not renewed and guidance on how to resolve this issue. Thank you for your time and support. I look forward to your response.Microsoft Deprecates Graph CLI and Toolkit
Microsoft has depreciated the Microsoft Graph CLI and Graph Toolkit. It’s nice to see some rationalization in this area, but the real need is for better quality and coverage across all the Microsoft 365 administrative actions. Even after fourteen years of development, too many undocumented and private APIs exist in use today in places like the Microsoft 365 admin center, which is an unacceptable situation. You should vote for a feedback portal item (link in article) to ask Microsoft to do better. https://office365itpros.com/2025/09/02/microsoft-graph-inconsistencies/Viva Engage Community Membership

Can you help Thanks, Ciaran
SPF, DKIM and DMARC bypassed for guest users
I manage a small non-profit using Microsoft 365 Business Basic. Most of the people on our board of directors are added as unlicensed guest users so that they can participate in Teams chats and meetings and to access our Sharepoint without using up a license. The problem: any email sent from an internal licensed user (or shared mailbox) to one of these guest users completely bypasses our domain's SPF, DKIM and DMARC configuration, resulting in bounced emails (particularly for recipients using gmail). Mail sent from an internal licensed user to any external address NOT registered as a guest user correctly passes SPF, DKIM and DMARC checks. I gather that this is because guest users are viewed as "internal" despite having external email addresses, but it seems like a serious limitation if I cannot reliably send email to anyone who is a guest user. Is there any extra configuration I can do to enable SPF, DKIM and DMARC for email to guest users?
