Call SharePoint Server Subscription Edition REST API via App Only Authentication
Need to call SharePoint Server Subscription Edition REST API via App Only Authentication and found below article. https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs can i do this using TokenHelper.cs as suggested in the article? Seems request tires to access ACS because of below settings in TokenHelper.cs and requests timeout since the code is executed from a Server where no access to Azure ACS. private static string GlobalEndPointPrefix = "accounts"; private static string AcsHostUrl = "accesscontrol.windows.net"; Any support on how to do this for On-Prem SharePoint is really appreciated.sudeshwithanageJan 05, 2026Copper Contributor18Views0likes0CommentsDefault - "Open Read Only" for Office Files
Looking for a way to set the default behaviour to "open read only" for office files stored in SharePoint I know that you can set this per document (https://support.microsoft.com/en-au/office/make-a-document-read-only-in-word-5c25909c-46d9-4eb0-9d1f-d072a560e340) but we want that to be the default behaviour for all documents stored in SharePoint. is this possible ???44Views0likes2CommentsInvalidRequest Error for Attachments in Personal Microsoft Lists
Hello Community, I’m experiencing a persistent issue with Microsoft Lists (personal account, accessed via web on Windows 11 using Microsoft Edge). Problem: All attachments in my personal Lists return the following error when clicked: {"error":{"code":"invalidRequest","message":"Invalid request"}} This happens for both my oldest and recently uploaded attachments. This does NOT happen to NEW list items as of today and onwards I verified that attachments were successfully uploaded at the time, but now none are accessible. Age of my uploads stretch from 2023 to this time Environment: Windows 11 (fully updated) Microsoft Edge (latest version) Lists accessed via web (not the app) Personal Microsoft account (not work/school) No recent migration, rename, or permissions changes. Steps Tried: Renamed the list (removed special character “ø” from the name). Uploaded new attachments Checked that both my sub-items are inaccessible (attachment and personal attachment fields used separately from item to item. No double uploads) Checked OneDrive and Recycle Bin — no attachments visible. No access to “Site contents” since this is a personal account. Questions: Is this a known issue with personal Lists attachments? Are attachments stored in a hidden folder in OneDrive/SharePoint for personal accounts? If so, what is the usual path? Is there any way to recover these attachments or fix the invalidRequest error? Impact: I used Lists to manage and store receipts, and now all attachments appear broken. This is critical for my workflow. Any guidance or escalation would be greatly appreciated!fredNor92Jan 03, 2026Copper Contributor16Views0likes0CommentsCustomizing Search Result Display for .eml files at Site Collection level
Hi everyone, I’ve noticed a specific behavior regarding how SharePoint handles search results for .eml files and I am looking for a way to optimize this. Observation: Following a migration of emails into a SharePoint Site Collection, the search results currently display the Filename as the primary heading. Since these filenames are GUIDs, they provide no context to the users. The Title property (which contains the actual email subject) is available but is not being used as the main display value in the search results. Goal: The objective is to change the search result display so that the Title/Subject is shown instead of the Filename, making the results meaningful for the end-users. Current Constraints: Permissions: Access is limited to Site Collection Administrator (no Tenant Admin access). Environment: Must remain Out-Of-The-Box. PnP Modern Search or other third-party web parts cannot be deployed in this environment. Scope: Changes need to be implemented at the Site Collection level, as tenant-wide search schema modifications are currently not an option. Technical Question: Is there a way to influence the result display logic or the mapping of Managed Properties specifically within the Site Search Schema to achieve this? I am looking for guidance on whether this can be solved through site-level configuration or if there are other OOTB workarounds to prioritize the Title property in the search UI. Any insights or documentation on how to approach this at the site level would be greatly appreciated.koch_kiDec 25, 2025Copper Contributor66Views1like2CommentsExternal Access to Sharepoint Problem
Apologies, I am not technical and I am struggling to solve an issue with an external user that I am trying to grant access to a folder. They get the link and are shown as sharing on the file but they can't gain access without a password. This is not a condition that I have set? This whole experience has been a bit of a nightmare, if I were techie then I have the feeling I would understand the advice and could solve the issue, but nothing seems written in plain english for a lay person!TonyWinsBidsDec 22, 2025Copper Contributor51Views0likes1CommentSharepoint deleting data and sites
Hello, We have noticed an issue that started about a year ago in which data is being deleted in Sharepoint. When looking at this data in the Recycle bin, it will show it was modified/deleted by specific Users but these user deny ever doing such a thing. It is at the point in which we believe the Sharepoint system itself is actually deleting data possibly due to a bug. It would be odd for the employees tagged in the Modified By field to have deleted it. Our data is backed up so recovering any deleted items isn't the issue. The issue is that we are trying to get Microsoft to investigate. We have submitted tickets through the MS 365 portal but they state they only work on break/fix issues. Any recommendations? I can see searching the internet this issue has come up for many others in the past.ITAFCDec 19, 2025Copper Contributor53Views1like1Comment
