Delete current minor version of a document


There is a document already published to 1.0 and a user has accidently created a draft version 1.1. This new minor version must be deleted so the document is back to version 1.0.


In this particular case the version history contains the following versions: 0.1, 0.2, 0.3, 1.0, 1.1. There is no way to delete versions 1.0 and 1.1 neither using the UI nor programmatically. They both have IsCurrentVersion=True and trying to delete any of these two versions throws an exception clearly stating that a current version of a document cannot be deleted.
After failing to delete it programmatically I tried by unpublishing version 1.0 but that doesn’t solve the problem because version 1.1 is still there.
After some experiments with the library settings I found a workaround to bring the version history as it was before creating the minor version 1.1.


By temporarily disabling the versioning for the document library I was able to modify and bring the version history as it was before.
This solution only works if there is only one draft version, in our case 1.1. If more minor versions are created (1.2 or more) then this solution will not work.

For demonstration purposes let’s say the version history for a document is: 0.1, 0.2, 0.3, 1.0, 1.1. We want to delete 1.1 and keep the other versions.


  1. Disable versioning for the library
  2. Checkout and check-in the document
  3. Turn the versioning back on. Version history now is 0.1, 0.2, 0.3, 1.1
  4. Unpublish the document. Now the Unpublish option is available for 1.1. (After this step the version history is 0.1, 0.2, 0.3, 0.4)
  5. Checkout then Major-check in the document. (After this step the version history is 0.1, 0.2, 0.3, 0.4, 1.0)
  6. Delete the minor version created in step 5 (In our example version 0.4). (The resulting version history: 0.1, 0.2, 0.3, 1.0, i.e. same as before 1.1 has been created)

If the contents of 1.0 and 1.1 are different then before performing the steps above save the file version 1.0 locally and uploaded it to the library after step 4.

On a production environment it’s important to choose a proper time to perform these steps when no user is working with the library otherwise they may create major versions by accident during the time when versioning is off for the library. For more information how temporarily disabling versioning affects a list check my other post Effects of temporarily disabling versioning for a SharePoint document library

If you have event receivers registered for the document library you may want to remove them temporarily if you don’t get the behaviour explained in the steps above. To remove and add back the event receivers for a list check my other post Add, Modify or Delete List Event Receivers with PowerShell

    Hi, this solution does not work for me.

    Looking at step 3, it seems like somehow steps 1 and 2 are removing the published version 1.0 which does not happen for me and it does not make sense either.
    After following steps 1, 2 and 3, version 1.0 is still there and still published, while version 1.1 does not have the option to unpublish.

    I discovered that content approval needs to be disabled as well for this to work. Namely, step 1 should be “Disable versioning and content approval for the library”. It might be my fault for assuming you had content approval enabled for the library.

      Hi Mihail,

      I think content approval was not enabled in my case. It was in 2014 and I don’t remember. But it’s also possible for the behaviour of SP to change over time with the new updates.
      Thanks for your comment. It will help others having the same problem.
