failed to open excel document (active workbook retrieval error)



A flow I've had running fine for months suddenly returns an error when trying to open an Excel file.

The file is in a synchronized sharepoint folder, that the flow tries to access through its path in the explorer.

On attempting to run the Launch Excel step, it returns an error "Failed to open excel document" (active workbook retrieval error).

I already put a Terminate Process (EXCEL) before the Launch Excel step, but this doesn't helpt.

Thank you for the fast reply. This solved the problem. The problem occurred again soon after, but restarting the laptop solved it again.

Since I had the same issue (after months without any issues), and repair and reinstall Office and PAD did not work, I fix it by doing the following: I added the "Launch Excel"-step into another PAD flow, and used the "Run desktop flow" to run the newly created PAD-flow, which worked. I'm just gonna leave it as is, since it's working now.

Hi All.

Today (Monday) I also got this error on a flow that worked perfectly on Friday.

I tried repairing the office installation, uninstalled and reinstalled power automate desktop, switched off the computer, killed processes in windows's task manager. I cleared the power automate cache, created copies of my documents on my desktop (since they were originally on my one drive).


So far no chance.

I also have no idea how to find out what might cause the issue.

I am on Power Automate


Thanks for the help.

Hi @freeeeea,


Did you try my solution? It's easy to set up, and it works for me (see screenshot below). 

Unfortunately, I highly doubt it's something Microsoft will fix, as they're really good at purchasing existing software, and uses little effort to fix existing bugs, and just leaves them as is, so we have to find our own workarounds....




Thanks AlexTheKidd for the reply.


I did not try your suggestion. I did not completely understand how to set it up and how this could resolve the issue.

In my flow I open two different existing excels as read only to read values, populate a list and then close them.

These values are stored to perform validation and confirm that all instances of a variable contain valid entries.

So I need to be able to pass variables from a flow to another.

Then I open a second excel where I write down all the values of around 30 attributes that I gathered from looking at files and validating their filenames and file paths.


The process should work for a big amount of files.


Today the process stopped at opening the excels but I don't think that, if it is a bug, it is impacting only excels.

I have other flows where reading files from a folder and writing to a text file seem impacted.

As most of my flows work on one drive maybe it is a cloud issue or internet speed.


Really strange.

Hi @freeeeea ,


Why it stopped working? No idea. I had the same issue.


How I solved the issue:

Created a new flow, and only have 1 actionin the flow, which is "Run Desktop Flow", which again directs to run the actual flow. Here is are screenshots of my flows, and how it works:


The one called HANDTOOLS - v1 is the one containing all my flows, but it fails when running directly, so I created the temp flow - screenshot of the entire flow in the temp flow, which only has 1 action:


Why this works, I have no idea, but if it works, don't touch it 🙂

Hi again @freeeeea,

I just stumbled across this post:

where they state the issue is that the Excel process is terminated.

Maybe that could be your issue? I'm currently looking into if it fixes it on my end, but I'll have to wait until tomorrow to test it...

Thanks Alex.


Fortunately I am not killing the excel instances and then try to use the contents of the "excel object".

In the mean time, It looks like one of the following actions actually did the trick.


1 - Repair Office

2 - Uninstall / Reinstall Power Automate Desktop

3 - Clear the Power Automate Desktop Cache

4 - Clear all Credentials stored in Windows Credentials

5 - Restart the computer


I was able to use the same flows from a different machine, so it seemed to me that a mismatch with the credentials of Power Automate, OneDrive is the probable culprit.


Still, quite unhappy about the amount of digging needed in order to try to find out.

Hi @freeeeea,


Interesting - PAD cache? Had no idea that even existed! It's great to hear that it's working for you.

I just removed the "terminate Excel" I had in the flow, and it now works for me! 

Totally agree on the amount of times I've tried to fix this issue, especially when it started randomly. 

I'll make sure to test your links if I ever experience it again!


But now that we're both back to figuring out other issues/workarounds, I wish you great travels in your continuous journey ahead - until next time 🙂

I know that I am late to the party, however what fixed it for me was making the instance visible when launching Excel.

Hi All,

This is caused by OneDrive still accessing the Excel file, which then deems the file to be 'open'.


This causes the error 'Active workbook retrieval error'.



- Terminate OneDrive

- Launch OneDrive

- Launch Excel


This may look something like this 


1 - Terminate Process 'OneDrive'

2 - Run Application - C:\Program Files\Microsoft OneDrive\OneDrive.exe

   - This may not be your OneDrive location

3 - Launch Excel

I had the same issue and solved it firstly by opening the Excel file, which was greyed out. Then, under the 'View' tab in Excel, I have unhidden the file (I don't know why this file was hidden??) and saved the file afterwards.


Then, just have run the flow and it worked as expected.

September User Group Success Story: Reading Dynamics 365 & Power Platform User Group

The Reading Dynamics 365 and Power Platform User Group is a community-driven initiative that started in September 2022. It has quickly earned recognition for its enthusiastic leadership and resilience in the face of challenges. With a focus on promoting learning and networking among professionals in the Dynamics 365 and Power Platform ecosystem, the group has grown steadily and gained a reputation for its commitment to its members!   The group, which had its inaugural event in January 2023 at the Microsoft UK Headquarters in Reading, has since organized three successful gatherings, including a recent social lunch. They maintain a regular schedule of four events per year, each attended by an average of 20-25 enthusiastic participants who enjoy engaging talks and, of course, pizza.   The Reading User Group's presence is primarily spread through LinkedIn and Meetup, with the support of the wider community. This thriving community is managed by a dedicated team consisting of Fraser Dear, Tim Leung, and Andrew Bibby, who serves as the main point of contact for the UK Dynamics 365 and Power Platform User Groups.   Andrew Bibby, an active figure in the Dynamics 365 and Power Platform community, nominated this group due to his admiration for the Reading UK User Group's efforts. He emphasized their remarkable enthusiasm and success in running the group, noting that they navigated challenges such as finding venues with resilience and smiles on their faces. Despite being a relatively new group with 20-30 members, they have managed to achieve high attendance at their meetings.   The group's journey began when Fraser Dear moved to the Reading area and realized the absence of a user group catering to professionals in the Dynamics 365 and Power Platform space. He reached out to Andrew, who provided valuable guidance and support, allowing the Reading User Group to officially join the UK Dynamics 365 and Power Platform User Groups community.   One of the group's notable achievements was overcoming the challenge of finding a suitable venue. Initially, their "home" was the Microsoft UK HQ in Reading. However, due to office closures, they had to seek a new location with limited time. Fortunately, a connection with Stephanie Stacey from Microsoft led them to Reading College and its Institute of Technology. The college generously offered them event space and support, forging a mutually beneficial partnership where the group promotes the Institute and encourages its members to support the next generation of IT professionals.   With the dedication of its leadership team, the Reading Dynamics 365 and Power Platform User Group is poised to continue growing and thriving! Their story exemplifies the power of community-driven initiatives and the positive impact they can have on professional development and networking in the tech industry. As they move forward with their upcoming events and collaborations with Reading College, the group is likely to remain a valuable resource for professionals in the Reading area and beyond.

September featured user group leader

 Ayonija Shatakshi, a seasoned senior consultant at Improving, Ohio, is a passionate advocate for M365, SharePoint, Power Platform, and Azure, recognizing how they synergize to deliver top-notch solutions. Recently, we asked Ayonija to share her journey as a user group leader, shedding light on her motivations and the benefits she's reaped from her community involvement.      Ayonija embarked on her role as a user group leader in December 2022, driven by a desire to explore how the community leveraged various Power Platform components. When she couldn't find a suitable local group, she decided to create one herself!    Speaking about the impact of the community on her professional and personal growth, Ayonija says, "It's fascinating to witness how everyone navigates the world of Power Platform, dealing with license constraints and keeping up with new features. There's so much to learn from their experiences.:        Her favorite aspect of being a user group leader is the opportunity to network and engage in face-to-face discussions with fellow enthusiasts, fostering deeper connections within the community. Offering advice to budding user group leaders, Ayonija emphasized the importance of communication and consistency, two pillars that sustain any successful community initiative.      When asked why she encourages others to become user group leaders, Ayonija said, "Being part of a user group is one of the best ways to connect with experienced professionals in the same field and glean knowledge from them. If there isn't a local group, consider starting one; you'll soon find like-minded individuals."      Her highlight from the past year as a user group leader was witnessing consistent growth within the group, a testament to the thriving community she has nurtured. Advocating for user group participation, Ayonija stated, "It's the fastest route to learning from the community, gaining insights, and staying updated on industry trends."   Check out her group: Cleveland Power Platform User Group
