Microsoft Graph: Private channel SharePoint site URL naming appears to have changed
📄 Question We are creating private channels using the Microsoft Graph API: POST https://graph.microsoft.com/v1.0/teams/{team-id}/channels With the following payload: { "@odata.type": "#microsoft.graph.channel", "displayName": "Project-Channel-001", "description": "Sample private channel for testing", "membershipType": "private", "members": [ { "@odata.type": "#microsoft.graph.aadUserConversationMember", "******@odata.bind": "https://graph.microsoft.com/v1.0/users/{user-id}", "roles": ["owner"] } ] } 🔍 Observed Behavior When the private channel is created, the associated SharePoint site is provisioned automatically (as expected). However, the URL format appears to have changed. Previously observed behavior: https://{tenant}.sharepoint.com/sites/ProjectTeamURL-Project-Channel-001 Current behavior: https://{tenant}.sharepoint.com/sites/ProjectTeamName-Project-Channel-001 ❗ Impact This change introduces several issues: Breaks deterministic URL generation logic Produces longer and less predictable URLs Introduces dependency on display name, which is mutable and may contain unexpected characters Impacts existing automation and integrations relying on the previous pattern ❓ Questions Has there been a recent change in how SharePoint site URLs are generated for private channels? Is this behavior intentional and documented, or a regression? Is there any way (via Graph or otherwise) to: Control the generated SharePoint site URL, or Retrieve the final site URL deterministically without relying on pattern assumptions? Is the previous {ParentTeamUrl}-{ChannelName} format still expected in some scenarios, or has it been deprecated? 🧪 Additional Notes This behavior is observed when creating channels via Microsoft Graph (v1.0) The issue is reproducible across multiple test scenarios 🙏 Any clarification from Microsoft or others encountering this would be appreciated.
Slow UI update for deleted events
I've built an integration that continuously syncs events between an external scheduling system and Exchange Online using Microsoft Graph. I'm observing a recurring issue when deleting calendar events via Graph: A DELETE request to Graph returns success (204 No Content). A subsequent GET /events/{id} returns 404, confirming the event is deleted server-side. However, the event continues to appear in the Outlook UI (both Outlook Web and desktop) for an extended period (sometimes hours), even after page reloads or app restarts. The odd behaviour The event is still displayed in the user interface for up to several hours The event persist through page reloads If the user clicks the event it opens briefly and immediately closes, the event disappears from the UI afterward. Additional details Delete endpoint: /users/{id}/events/{id} Graph response: 204 No Content Verified deletion via GET → 404 Reproduces in both Outlook Web and Outlook desktop Questions Is this a known Outlook client caching or calendar view indexing issue? Is there a way to force client reconciliation after deletes? Are there Graph or Exchange constraints around rapid create/update/delete cycles that could cause this UI inconsistency?
O365 Group email settings
I am in the middle of trying to create some automated routines that create groups in O365 and add/remove members from them as needed. One of things I ran into is that when an email is sent to the group, the emails are not going into each members' inbox and are only visible in Outlook through "Go to groups" in the left hand menu. I can see the settings that need to be set but can't set them because either, A: it just doesn't do it or B: says I don't have permission. Doing this through C# and the Graph SDK The two items I think I need to turn on are below. What permissions are needed to be able to manage those settings but NOT be able to have access to anyone and everyones' email boxes, emails, etc or is there another way to do this?

Query Regarding Duplicate Message IDs from Microsoft Graph API
Hello Microsoft Support Team, I am currently using the Microsoft Graph API to fetch email messages from the inbox of a my support email in my PHP application. However, I am encountering an issue where the API returns duplicate message IDs for emails. This is causing problems as emails with the same id are being processed multiple times, which results in duplicate ticket creation in my CRM system. To avoid this, I am currently checking and skipping duplicate IDs manually in my application. However, I would like to understand the root cause of these duplicates and whether there is an official recommendation or best practice to handle such cases effectively. Here are some additional details: API Endpoint: GET graph.microsoft.com/beta/users/$userEmailEncoded/mailFolders/Inbox/messages?\$top=20&\$orderby=receivedDateTime%20desc Issue: Duplicate message IDs (id) returned for the same email. Current Handling: I am skipping already processed emails using a tracking for message IDs to prevent duplicate ticket creation. Additionally, I have a few more queries regarding the use of internetMessageId and fetching attachments: Problem with internetMessageId: When I use internetMessageId, the internetMessageId of a replied message returns null. How can I use this ID effectively to manage or track message threads and replies? Attachments with internetMessageId: Is it possible to fetch attachments for a message using the internetMessageId? I am trying to retrieve attachments for a specific email using this ID, but I am not sure how to do this efficiently. Could you please advise on the following: Is there a recommended way to handle or filter out duplicate emails when fetching email data from the Graph API? Is there any mechanism in the API to ensure unique messages, especially when calling this endpoint frequently? How can I properly use internetMessageId for tracking message threads and replies, and why is it returning null for replied messages? Can I retrieve attachments using internetMessageId or is there another method for doing so? I would greatly appreciate any guidance or suggestions you can provide. Thank you for your time and assistance. Best regards, Krishna Adroja email address removed for privacy reasons

Hi everyone, I'm currently working with the Microsoft Graph /list API to retrieve files from a SharePoint document library and then using the /content endpoint to download each file. After processing approximately 1000 records, I began receiving 429 Too Many Requests errors. On reviewing the API traffic from my application, I found that we're only making about 150 API calls per minute, which is well below the documented thresholds. According to Microsoft’s guidance on avoiding throttling in SharePoint Online (link to docs), the usage is nowhere near the stated API or egress limits — especially the tenant-level thresholds like 1,200 API calls/min or 100GB/hour egress. What’s puzzling is the lack of transparency — I’m unable to find any dashboards, logs, or reports in Microsoft 365 or Entra that show how many API requests are being made or what limits are being approached. My questions: Are there any hidden or undocumented limits (e.g., per-user, per-app, or per-site collection)? Could /content downloads have higher cost per call or impact the limit differently? Is there any way to monitor detailed API usage against SharePoint or Graph API from the Microsoft portal? Would appreciate any guidance or insights from others who’ve faced similar issues! Thanks in advance!How to get a user P.O. Box from Active directory using Graph API
