Adobe Acrobat for Microsoft 365 - fill and sign not saving signature in brownser

I'm glad we're not alone.

This issue appears to be a bug at Adobe's end.  We're on the latest version of Edge.  This happens on Chrome too and after clearing Cache.  

I am not massively keen on publishing a video clip of the issue given it would expose our SharePoint site and set up.  Is there another way to discuss this - say over a video call?

To replicate this issue you can do the following - whilst signed in with your Adobe account:

1) Open a PDF from within SharePoint/OneDrive within the browser - 365 App

2) Go to Fill and Sign - enter a signature - for example - Joe Bloggs - 3.6.25

3) Click save and close

4) Sign a document, save it and close it

5) Open another PDF document

6) Go to fill and sign.  Normally, the Joe Bloggs - 3.6.25 signature would remain.  Right now - you have to set it again.

This causes issues when you are signing off multiple PDF documents that are saved in SharePoint.  Yes you can open in App and use the Desktop App which works fine - but the time it takes to add clicks and open the Desktop App is significant when working through lots of PDF approvals.  The flow is not good.

Is there any way this can be boosted to the development team?  They would see that the 'save' signature option is not working as intended - or as it did say a week ago.  

Since November 2024 we have worked in this way and it has worked fine.  We recall this happening once before and it fixed itself within a couple of hours.

And thank you AnandSri for your prior, swift response.

Hi,

We have the exact same issue since last Friday, it's quite annoying. The only workaround we found so far is to use the "Desktop" button  in the top right corner to open the PDF in the desktop app, then the saved signatures appears.

The SharePoint integration with Acrobat's desktop app is rather unpleasant to use, requiring multiple popups to be clicked each time. I hope Adobe fixes the web version of Acrobat for SharePoint soon.

Regards,

Hello!

I hope you are doing well, and thanks for reaching out.

Based on what you’ve described, it sounds like the Adobe Acrobat for Microsoft 365 plugin used within Microsoft SharePoint in the Edge browser is no longer retaining saved signatures between sessions. This was a previously working feature, and if it has recently stopped functioning. 

Try checking if the Adobe Acrobat extension is up to date in Edge, and also clear the browser cache once.

The signature retention is typically linked to your user profile in the browser or Adobe account. Ensure:

• You're logged into your Adobe account when using the extension.

• The Edge profile is active and not in guest/incognito mode.

Try adjusting Edge settings under Settings > Cookies and site permissions > PDF documents, and enabling “Always open PDF files externally”. However, it’s worth noting that this setting may no longer be available in the latest Edge builds, which could explain the recent change in behavior.

One workaround would be to:

• Manually reapply the signature for each document (if feasible).

• You can also open and sign the PDF directly using the desktop version of Acrobat, which continues to reliably retain signature data.

If the issue persists, please share the current version of Acrobat, the plug-in installed, the MS SharePoint and Edge versions, a quick video depicting the issue, and the logs from the affected machine and user profile. Download the log collector tool, run it, ensure all the log options are selected, try to reproduce the issue, close the tool. It will generate the logs and a log ID. Please share them with us for further investigation.

Thanks,

Anand Sri.
