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

[reliable_reliability3603]

Hello

As advised by the support helpline at Adobe - see below.

We use the Adobe Acrobat for Microsoft 365 plugin with Microsoft SharePoint.

Normally when you open a PDF in browser (Edge) - you can add a signature and save it.  When you open another PDF, the signature previously added is retained for use.  That feature has stopped working in the past week.  The signature is not being retained.

We suspect this is a bug/glitch - can anyone help?

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.

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.

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, has there been any updates to this issue? No matter what we try, we can't seem to fix the problem and our client is 100% against having to add a new signature every time and/or opening the pdfs in the local adobe app. (Adobe for Sharepoint)

Thank you

[jean-francois_4721]

We have done some internal testing with Adobe's SharePoint integration and when we assign an Acrobat Standard license to the user, their scanned signatures reappear in the "Fill and Sign" tab. This may be a paid feature now in Adobe for Sharepoint.

The only workaround we found so far for an unlicensed user is to open the PDF in the desktop app, which is a much slower workflow with all the popups you have to click.

[Thomassss_]

We have tried this, but no matter the licence we assigned our users the signatures never reappear, wether they are created inside the app, the web app or the SharePoint integration, signatures in the SharePoint integration don't appear / aren't saved when created. It was working in the past so that's why we're even more confused, the licence never changed and it just suddenly stopped working.

By way of update - the email communications I was having stopped.

We noticed the 'save signature' option has disappeared from the 365 Web app for SharePoint.

The latest comment from Adobe was as follows (and I have chased):

I hope you are doing well, and I appreciate you sharing the details and logs. 

We have logged an internal bug, and the Engineering team is working on a fix or a possible workaround. I will set up a Microsoft Teams session and send an invite shortly.

This was the position as at 4 June 2025 (before they removed the 'save signature' option. 

Question - will the feature return?  Will Adobe fix the issue?

I hope you are doing well, and we are sorry for the delayed response.

A fix has been rolled out. Please log out and then log in with the IMS account for the changes to take effect. Let us know if you get any error message.

Thanks for your time and cooperation.

Hello Anand,

On our side it seems to work. I did a logout/login and now I see my saved signature in Adobe's web view for SharePoint.

Thanks for your help!

Hello AnandSri,

Need your help!

We had tried from our site, some user working fine and some which is not.  At the same computer different users signed in will have different result. Some appear signature and some do not. For those appear will be fine when they login to other computer and if users with signature not save issues, it not work even switch computer.

Thanks

The feature is now working as you suggest for me - thank you Anand.

[AnandSri]

Hello @reliable_reliability3603

Thank you for confirming that the feature is working at your end.

@jin_geeng_8449

Thank you for sharing the details. If the signature is not saved for some users on the same computer, where other users are able to use the feature, it seems to be an issue with the settings for those user profiles. Please ensure that the users refresh their login session for the changes to take effect.

Log Out and Log Back In: 

• • Log out of the Adobe IMS account from Acrobat and the browser.
  • Log back in to refresh the session and sync profile data.

Clear Browser Cache and Cookies:

• • Especially for users accessing Acrobat via Microsoft Edge or Chrome, clearing the cache can resolve session-related issues.

If the issue persists, please collect the following:

• Acrobat version, OS version
• Browser and SharePoint plugin versions.
• User details. Please share the user details with me only via direct/private message. Click on my user profile and select the message option. 

Thanks,

Anand Sri.
