There are many possible causes. Without more detailed information about your digital environment (operating system, OneDrive version, etc.), it's impossible to say for sure. Here are some possible causes, but we don't guarantee the exact cause.

You saw:

  • 29.7GB used out of 50GB (41% free),
  • But syncing failed, and uploads were blocked with "storage full" messages,
  • OneDrive only resumed working after dropping usage to ~24.5GB.

This suggests there's an invisible upper limit being hit somewhere—let’s explore the possible reasons.

Possible Causes

Indexing or Shadow File Limits

Phantom/Orphaned Files

Quota Sync Delay / Outdated Metadata

Regional Service Limitations (India-specific?)

Bug in Sync Engine or Storage Enforcement Logic

 

Your case strongly points to OneDrive triggering sync blocking once ~30GB is used, despite a 50GB quota. This is likely:

A conservative internal safety buffer,

Or a storage sync bug.

 

Hope this information helps you a little.
