This is still a problem.  Please fix this kind of thing.  Without functionality like this I might as well just use sharepoint. 7.12.1

Same issue in Confluence 7.4.3

Hi

Also same issue shows up in version 7.0.1

Hi Guys

This is madness !

Same issue using Confluence server 6.15.6

Same behaviour with 6.15.6.

The error does not occur with every document. First thought that it has do with animated Powerpoints. But they are all simple and small.

Converting to ppt helps, but you might ruin your Powerpoint.

Same happens with Confluence 6.9.1 which are we using.

WORKAROUND: Converting to .ppt resolves this issue.

We are using Confluence Server 6.6 at the moment and experience this issue as well.

I too am facing this issue with Confluence Server 6.13.0. The error "There was a problem converting this attachment" appears after inserting a PowerPoint macro.

Same problem here on Confluence Server 6.4.3. Powerpoint slides are frequently used during meetings and it's a pity we can't visualize them effectively in Confluence. We'd like people to collaborate and share information in Confluence and it's hard to do that when information is buried in attachments instead of being visualized on the page.

A year later ... still occurring.   

Again: Please reopen this issue

This still occurs for users at times, yet this issue is still closed. This should be reopened.

This still happens on newer versions of Confluence sometimes. We have to save the pptx file as a ppt to get it to work.

Please reopen this issue

Still occuring on 6.3.2

Still occurring on 6.0.5

Dear All,

Thanks for raising this issue. I believe this bug is already fixed with our Confluence 6.0.4
Please upgrade to that version to have the fix

Atlassian

Reproduced on Confluence (Server) 5.9.5

Still happening in 5.9.7...

on 5.10.3 works!

Why is this still not fixed? Since 2014!?

Still unassigned. Come on Atlassian!

Conversion task timed out for attachment
We have this issue with Confluence Data Center 5.8.18 as the conversion process times out. This happens many times each day when users attempt to open a page using the viewppt macro:

Example

25-Mar-2016  [http-nio-8080-exec-14] INFO com.benryan.conversion.PPTSlideServlet - Conversion task timed out for attachment : SomeFileName.pptx with page number 0, waited : 300, now executing in background.

Please let us know when a fix is to be made which will resolve this reported problem as I see the issue is not yet 'Assigned' for work after having been open for over a year and a half.

Please, please escalate the priority to fix this bug. Our org uses Office 2013 so none of our pptx files are displaying (the error message comes up). This is a huge hindrance to using all these cool collaboration features released in 5.7.4.

As workaround you can save your.pptx file in ‘PowerPoint Picture Presentation (*.pptx)’ format.

We have the same issue with PDFs in Confluence 5.6.6. Uploaded a PDF, used the PDF view macro and upon saving, receive the same error.

Added another attachment to test against.

A new wrinkle in behavior, part of the PPTX document renders (text), but images in the PPTX document don't. Replicated up through 5.6.5.

Same issue for me on certain pptx files.

Hi,
we have Confluence 5.6.3, and Office Connector 3..3.8 and can confirm the bug.
The powerpoint file was created in Office 2010
