organizations storage is full

The banner refers to the organization’s pooled tenant storage, not the personal quota shown at the bottom of OneDrive.

Even if the individual OneDrive shows only 2.6 GB of 100 GB used, OneDrive can become read‑only when:

1. The organization has exceeded its total pooled storage limit for Microsoft 365.
2. A large shared folder or shared content counted against the tenant has pushed the organization over its limit.

In that situation, OneDrive goes into a restricted state:

• No new files can be uploaded, edited, or synced.
• Existing files remain but are read‑only.

Resolution requires action by the organization’s IT admin, not by the end user:

1. The IT department must either:
   • Free up space (delete or archive data, including large shared folders), or
   • Purchase additional Microsoft 365/OneDrive storage for the tenant.
2. Once the organization’s pooled storage is back under quota, OneDrive will return to normal (write) mode.

Locally, only basic cleanup is possible (deleting files, emptying the recycle bin), but that will not fix the tenant‑wide “organization storage is full” condition if the tenant itself is over its pooled limit.
