Microsoft Edge PDF Reader - signature validation warning for official signatures
Since the last edge update we are running into the following issue, which triggers support tickets on our side. It seems that the edge internal PDF Reader now supports validation of digital PDF signatures. This new feature however is incomplete and causes a lot of confusion for edge users. "Official" signatures are labeled as "Unknown Signature" and "The validity of the signature is still unknown": "Official signatures" means qualified signatures from members of the EUTL - the European trust list as defined in ETSI TS 119 612 („Trusted Lists“): [...] the European Commission publishes a central list with links to the locations where the national trusted lists are published as notified by Member States. This central list, called the List Of Trusted Lists (LOTL), is available in both a human readable format and in a format suitable for automated (machine) processing XML. Parts of the edge PDF reader seems to come from *dobe itself which adds additional confusion since in their products (*dobe reader, acrobat etc) the signatures are correctly verified. They support this list for several years now (next to their own AATL list). I tried to find out whether this feature is 'work-in-progress' or it is a bug however the last published roadmap is quite old and doesn't give helpful information regarding this aspect. So my question is: Is full support of PDF signature validation including support of the EUTL planned and if so when?
Edge Pdf Viewer does not support page=Fit (only FitV or FitH works)
Dear community, I found that the Edge Pdf Viewer does not allow to display a pdf so that its first page fully fits into the window (no part of the PDF is out of the viewport). You can use the following URL to verify: https://creativelab.berkeley.edu/wp-content/uploads/2019/12/1920X1080-HORIZONTAL-template.pdf#page=1&view=Fit Test Case 1 When the window width gets too small, the window will display a horizontal scrollbar instead of scaling the pdf to fit the width: Test Case 2 When the window height gets too small, the window will display a vertical scrollbar instead of scaling the pdf to fit the height: When I use either FitV or FitH, the respective behaviour is as expected. But I need to combine both behaviours, and thus Fit would be the right option, which seems to be ignored by Edge. When I test the same parameters in other Browsers that use a Chromium engine, it works. Microsoft Edge Version 141.0.3537.85 (Official Build) (64-Bit) Windows 11 Thanks for any advice and thoughts! If there is a dedicated place to create a bug report, please let me know.
Edge Read Aloud feature fails on landscape PDF documents with tables.
I've encountered an issue with the Read Aloud feature in Microsoft Edge when opening PDF documents in landscape orientation that contain tables. The Read Aloud option is available and can be activated, but it gets stuck loading indefinitely and never starts reading. No error message is shown. In contrast, the same feature works perfectly with portrait-oriented PDFs, even when those PDFs include tables. I tested this on both Windows and macOS with up-to-date Edge versions. The issue appears to be consistent and not OS-specific. My clients use tables in landscape PDFs for better readability and formatting. It’s unclear whether the problem is due to the landscape orientation alone or the combination of landscape + tables. However, tables in portrait PDFs do not cause any issues. Has anyone else experienced this behavior? Is there a known fix or workaround? Would appreciate any feedback or confirmation from the Edge team.Sharing: PDF readers that support Purview labels
As I was researching on Adobe Acrobat reader and Sensitivity labels, I decided to check if the common alternative PDF readers out there are able to support Purview MIP Sensitivity labels. There is already a published documentation on this for SharePoint-Compatible PDF readers that supports Microsoft IRM: https://learn.microsoft.com/en-us/purview/sp-compatible-pdf-readers-for-irm (last updated Nov-2023) but I wanted to see if these same PDF readers supports the ability for end-users to use/ select labels similar to that of Adobe Acrobat As of 11-June-2025; atleast one of them clearly do: Nitro PDF: Yes. Documentation shows that users can see and use the sensitivity labels. PDF -X.change Editor: Yes. Documentation show that users can see and use the sensitivity labels. (check the official website, I can't hyperlink it because the site is blocked. FOX PDF editor: No. Documentation only states RMS and not clear if it show Purview labels. This is for F.O.X.I.T editor (spelled without the ".") but for some reason there is a community ban on that word and it won't allow me to post the full name PDFescape: No. Sumatra PDF: No Okular: No If there are other PDF readers that I've missed, I encourage you list it down in the comment below. Would love to grow this list.Can someone guide me on how to extract specific pages from a PDF without messing up the formatting?
I have a large PDF document, but I only need a few pages from it for a project. I tried using some online tools, but the formatting got messed up, fonts changed, and sometimes images shifted. I want a clean and reliable way to split or extract pages without losing quality. Any good suggestions?"
Onedrive has stopped creating folders
I have recently implemented the Graph api to: create in a shared folder various directories with names like this => "uc_123455"; on each folder created, the api upload pdfs inside it ; the problem: it starts ok but after a time it just stop creating folder, it has a total of almost 3500 folders to create and stops after 1000. the code works like this: it first get the access_token from microsoft and load the Graph then get the shared folder ID $this->graph = new Graph(); $this->graph->setAccessToken($this->accessToken); $this->directory_id = $this->fetchDirectoryId($this->graph); then i start looping: first it create the name based on what part is of the loop $subfolderName = "UC_" . $customer->numero_uc; after this is used to create the folder on this function $folder = $this->createIntoDirectory($this->directory_id[0], $this->graph, $subfolderName); and this function works like this public function createIntoDirectory(string $folderId, Graph $graph, string $ucNumber): string|bool { try { $response = $graph->createRequest('POST', "/me/drives/" . $this->drive_id . "/items/$folderId/children") ->attachBody(json_encode([ "name" => $ucNumber, "folder" => new stdClass() ], JSON_THROW_ON_ERROR)) ->setReturnType(DriveItem::class) ->execute(); return $response->getId(); } catch (GuzzleException|GraphException) { return $this->fetchExistenteDirectory($folderId, $graph, $ucNumber); } } if already exist an Folder with the name it falls in the exception and call to another function that return the id of the already created folder (I did this in case any pdfs weren't sent to the folder) heres the function: public function fetchExistenteDirectory(string $folderId, Graph $graph, string $ucNumber): string|bool { try { $folder = $graph->createRequest('GET', "/me/drives/" . $this->drive_id . "/items/$folderId/children") ->setReturnType(DriveItem::class) ->execute(); foreach ($folder as $item) { if ($item->getName() === $ucNumber) { return $item->getId(); } } return false; } catch (GuzzleException|GraphException) { return false; } } are there problems with my code to stop generation folders? because it works 100% fine, until then it stops questions like: where is the pdf? the pdf are converted images from urls that i fetch from my db what is UC: is like users, it come from portuguese word "unidade consumidora" or "consumer unit", each of then come from an array that i fetch from my db if it has any questions about the code or the process just ask. Thanks (english isn't my mother tongue, so sorry for any grammatical error)
Adobe Microsoft
Dear community, Alot of my users are getting a file not found error when opening links we send them to directly open the adobe files in SharePoint. Is there a Microsoft friendly PDF option that will allow a PDF to be edited in browser or in file to save back to SharePoint? We have Word, Excel and Autocad files that get combined (currently in Adobe) into a single file for editing. Adobe is not working well for us, as most know, to edit in SharePoint flows.
