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.
InvalidRequest 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!
Group Calendar Web Part Pop Up Color
We have created a branding theme for modern sharepoint sites to match corporate colors. When clinking on a Group Calendar event, the pop up now applies a background color we didn't have in the theme as primary or secondary. Just seems to be auto selected by SP. It's too dark to read the text. I've found the Them in the classic _catalog Theme Gallery and can pull the theme into NotePad to read it but can't seem to tell which variable controls the background of pop ups. Just need it to be white (ffffff). Anyone have a solution? {"name":"(Company Theme Name)","isInverted":false,"palette":{"themeDarker":"#243360","themePrimary":"#17244C","themeSecondary":"#5e6d9b","themeTertiary":"#7885af","themeLight":"#94a0c2","themeLighter":"#b3bcd6","themeLighterAlt":"#d6dbea","black":"#000000","neutralDark":"#201f1e","neutralPrimary":"#323130","neutralPrimaryAlt":"#3b3a39","neutralSecondary":"#605e5c","neutralTertiary":"#a19f9d","neutralTertiaryAlt":"#c8c8c8","neutralLight":"#eaeaea","neutralLighter":"#f4f4f4","neutralLighterAlt":"#f8f8f8","white":"#ffffff","neutralQuaternaryAlt":"#dadada","neutralQuaternary":"#d0d0d0"},"displayMode":"light","secondaryColors":{"light":[{"themePrimary":"#ffffff","backgroundColor":"#17244C"},{"themePrimary":"#6BC289"},{"themePrimary":"#ffffff","backgroundColor":"#6BC289"},{"themePrimary":"#26A9E1"},{"themePrimary":"#ffffff","backgroundColor":"#26A9E1"},{"themePrimary":"#1B75BC"},{"themePrimary":"#ffffff","backgroundColor":"#1B75BC"},{"themePrimary":"#E7EBF6"},{"themePrimary":"#ffffff","backgroundColor":"#E7EBF6"},{"themePrimary":"#ACBFE3"},{"themePrimary":"#ffffff","backgroundColor":"#ACBFE3"},{"themePrimary":"#B6BBBF"},{"themePrimary":"#ffffff","backgroundColor":"#B6BBBF"}],"dark":[]}}
How to improve performance of SPFx application?
Hello Everyone, We have created SPFx + React application. We have used the SPFx 1.21.1 version. We have used different npm packages into this project. The project works as expected functionally. We have checked the performance of the application using Lighthouse in Google Chrome. We found the below performance matrix from Lighthouse. We need to improve the performance of our SPFx application. Can anyone suggest the correct path to achieve the same? Thanks in Advance.Validation rule for postal code is being ignored
In the SharePoint list, there is a column “Country” and a column “Postal Code.” A validation rule has been configured in the list validation settings to ensure that when the country “Germany” is selected, only postal codes with exactly 5 digits can be saved. Currently, this validation rule is being completely ignored. Regardless of whether the postal code contains fewer, more, or no digits at all, the entry can always be saved. The validation does not take effect. Expected Behavior: When Germany is selected in the Country field, the entry should only be saved if the postal code contains exactly 5 numeric characters. If the input is invalid, an appropriate error message should appear and prevent saving. Actual Behavior: The validation rule is ignored. All inputs — including invalid postal codes — are saved. No error message is displayed. Impact: Incorrect or incomplete data is stored in the list. Manual corrections are required afterward, causing additional effort and increasing the risk of errors. The english version of formule we used =IF([Land]="Deutschland", IF(LEN([Postleitzahl])=5, 1, 0)) Why doesn't the validation work? Thank you in advance for your comments !
Size increase of .sppkg packages with heft/v1.22
After upgrading our solution to SPFx 1.22.rc-0 and switching to the new heft build toolchain our .sppkg packages have suddenly grown massively in size. They are more than double the size of the 1.21 version. Is there a reason for this? Is there anything we can do to reduce the package size back to what it was previously? Our main solution contains both web parts and list extensions, split into several bundles. Let me know what other details would be helpful.
Best Practice guide for stretched HA farm?
Hi, Im planning a SharePoint Subscription farm over 2 data centers. Should be pretty simple. Farm will consist of: dc 1: 1 spfe, 1 spapp, 1 sql dc 2: 1 spfe, 1 spapp, 1 sql Sql servers will be AlwaysOn. Im not sure how to set up the sp servers. Is there a preferred way to set it up, with how to? Our domains have 10gb connections so should be more than sufficient for stretched and HA. Can CA site be hosted from multiple servers? How are IPs/DNS/certs handled? What else do I need to get my head around? Thanks. Swan
Creating a slide show from a list webpart- Brainstorming
I have a SP list that i want to do a slideshow onto a page. It's basically to showcase achievements with a column (yes/no) to filter. it's all text, no pictures, just to displaying what happened and want it to be automatic to scroll through. tried hero webpart, and that did not work. Used list webpart which of course just shows the whole list. Though about making an power app, but i couldn't figure out how it would be able to showcase each item on the list automatically with me creating a new screen every time one is submitted. Any suggestions will be useful. ty
Is Creating Multiple ClientContext Instances Efficient in CSOM for one Site Url?
Is it efficient to create a new ClientContext for each site URL and for each query, such as getting site users, lists, groups, and group members from the Web object? These queries can return a very large number of items, and CSOM does not support paging when retrieving data from Web properties. Because of this, there is a risk of memory issues. In this case, is creating multiple ClientContext objects a good approach? Also, how does ClientContext work internally, and how does it handle memory and performance?
Patching SSSE
Having read all the documentation about CUs for SSSE I am still none the wiser as much of what is written, in the many related webpages, appears ambigous, unclear and contraditory to me. Could anyone clarify two points: If, say,the December 2025 CU is installed, does it included all security and non security fixes for all features in SSSE? Will Windows Update install the latest CE every month without any intervention including upgrading databases etc? Thanks for any advice ZDHow to restore a single file deleted 6 months ago - using M365 Backup?
My friend's company uses Sharepoint Online, but relevant folders are synced to their OneDrive so they manage everything in File Explorer. I have Microsoft 365 Backup enabled on their Sharepoint site. This company has all the parent folders in "Site Contents". These folders include Sales, HR, Clients, etc. I need to restore a single file out of Sales but it appears I need to restore the entire site first, sync the Sales folder from the site ending in /R0 to my OneDrive, then copy/paste from my File Explorer. Yes, I am a NOOB in Sharepoint. What's the right way to grab this file? And if it's ditching M365 Backup, then that's what I'll do, but I still need to get this file.SharePoint 2013 Newsfeed
I have a largely cosmetic problem. I have deleted and re-created someone's mysite (OneDrive). Now works fine. However, the landing page is the Newsfeed. It is stuck on an error about setting up OneDrive. It doesn't seem to have noticed OneDrive is fine. What I want to do is just reset the Newsfeed to its defaults. It looks like it is "stuck" as if OneDrive is broken. In SharePoint 2013 can I reset a NewsFeed page for a user in a non-disruptive way because the user now has data on their OneDrive. Stephen

Microsoft 365 Developer Program - Infinite "Loading your information" loop
Hello, I am trying to sign up for the Developer program as I am trying to complete the PL 400 certification and I want to complete the exercises that are part of the course. However, I am trying to get access to Power Apps and I can't due to not having a school or work email. So I tried using signing up for Developer Program using my personal email ....@hotmail.co.uk and it was giving me that infinite loop. Is there a way around this, I would really like access to power apps as it will really help me understand the course a lot better and actually allow me to practice what I am learning. Have other had this issue and how have they got around it. There is no way that only people with work or school emails want to complete these certifications.

MRT Layout Custom - how to become crazy 😭
Hi community, I'm currently trying to customize the search result layout in SharePoint. The JSON layout I created works correctly for SharePoint pages, but I would like to use the exact same layout for files, especially for: all files tagged as “procédures”, or files coming from a specific document library. Here are my current settings: The issue is not related to mapped properties. The refinable properties are working, and my verticals return the correct results when using this query. The problem is only with the layout, which does not apply to file results. Has anyone already faced this limitation or knows what might block the layout from rendering on file results? Thanks for your help!Property Demotion leads to infinite import cycles when integrating with SharePoint
Hi, we have built an integration with SharePoint that imports watches and imports files from connected SharePoint sites into our product for further processing. After that process is complete, we push some of the processing results back to a SharePoint list as metadata. In order to keep the extracted data up to date, even when file content changes after the initial upload/import, we subscribe to changes in the SharePoint site and re-import the file if its hash has changed since the last import. This process worked really well until we started processing some of the Microsoft file types (e.g. .docx, .msg, etc.). Apparently SharePoint Online will include metadata from list columns into these files in a process called "Property Demotion". Since this changes the file content, it triggers a re-import of the file. Due to the non-deterministic (AI-generated) nature of some of the metadata we extract, this re-import will likely result in different metadata values that are exported back to SharePoint - which of course triggers property demotion again, leading to an infinite cycle. What we have tried so far: Disable property demotion -> Not possible in SharePoint online as far as we know. Only export metadata if anything actually changed -> Only solves the issue if metadata is stable w.r.t. document content, which does not hold for our use-case. Skip re-imports occurring X minutes after the last metadata export -> While this works most of the time, it is fragile (what if the property demotion is delayed?) and worsens user-experience (what if a user edits the file within the X minute window?) Has anyone encountered the same issue before? How did you end up handling it? Thanks, JohannesGet FileName from ServerRedirectedEmbedUrl in Excel
