SharePoint Online Updated Feature: Limited-Access User Permission Lockdown Mode

Microsoft is at it again: Enabling features you didnt realize you needed until after a random update is applied, that leaves you banging your head against the desk for hours trying to figure out what has changed.  So is the case with a recent feature update called Limited-Access User Permission Lockdown Mode.

If you plan on setting unique permissions on a folder within a document library in Office365/SharePoint Online, you will need to disable this site feature that Microsoft has so graciously turned on for you.

You will know this feature has been enabled if you get this message when trying to apply unique permissions to a folder:

Here is Microsoft's notification regarding this change:

How To Fix One Drive for Business Sync Issues

A customer recently had an issue with syncing their SharePoint Online library with One-Drive for Business.  Some of the files were syncing properly, but some were throwing errors and displaying a red X.  Most of the time sync errors are caused by invalid characters or a bad file name, but this one wasn't the case.  Running repair didnt work, so I went in and manually cleared out all of the One Drive cache files and reconfigured the sync library.

Here's how to do that:

1. Close all your Office processes like groove.exe, msouc.exe,  msosync.exe, etc
2. Browse to “C:\Users\%username%\AppData\Local\Microsoft\Office\Spw” and delete all the content.
3. Go to “C:\Users\%username%\AppData\Local\Microsoft\Office\15.0\OfficeFileCache” and also delete all content from this folder.
4. After deleted everything,  start OneDrive again (using “C:\Program Files\Microsoft Office\Office15\GROOVE.EXE“)
5. Configure the sync library again

Even Microsoft support couldnt provide this information to me, so hopefully this help you if you ever have a sync issue that you just cannot fix.
