We’ve all gotten this error before.
This can mean any number of things. This article will describe a very specific situation that we discovered with one of our users.
Scenario
Library Settings Applicable to this Scenario
- Require documents to be checked out before they can be edited? = YES
This setting can be found by navigating to the library > Library Settings > Versioning Settings
- Open in the client application
This setting can be set at either the site collection level or the library level
- Site Collection = Site Actions > Site Settings > Site Collection Features

When the user clicks the Edit Document button they then receive this error

A problem occurred while contacting the server. If the problem continues, contact your administrator.
Cause
In this particular case, the cause was due to the site collection admin cutting and pasting the library into a manually created folder they had created in Explorer view.
Here are the steps they took to create the problem.
- User navigated to the site in the web interface
- Created 2 Document libraries named Library01 and Library02
- Open the site in Explorer View
- Right click and create new folder called Manually Created Folder (see image below)
- Right clicked Library02 and selected Cut
- Right clicked Manually Created Folder and selected Paste
- Library02 now resides in the newly created Manually Created Folder
Reason
The reason this breaks the library is due to existing pointers in the content database that will still point to the original location.
Resolution
In order to repair this issue, you must reverse all changes performed
- Open site in Explorer View
- Navigate to the Manually Created Folder location
- Right click Library02 and select Cut
- Navigate up to the original location the library was created in
- Right click and choose Paste
- Right click the Manually Created Folder and choose Delete
- The correct folder structure will look like the image below
It’s easy to mistake a library for a folder within a library in Explorer View, and you may not notice any issues until you start using other features/settings within your library. The best advice is to just leave it alone unless you’re fully aware of what you’re doing. Luckily for this user, this was easily remedied and we haven’t seen any major issues because of it. Hopefully that will remain the case.
Troubleshooting Tip
Navigate to the Library Settings of the affected library. Now examine the URL of the library. Are there any directories in the URL that do not match up to a sub site in your site structure? If so, this is likely the folder that was created by the user
