SharePoint: site Quota threshold exceeded, but no notifications received
I am looking at setting site quotas across our tenancy, to control storage growth by prompting users to think about what they're uploading, and whether old files can be deleted.
I set a low quota (1GB) on a test site, with "Allow notifications" checked, and a threshold set. I then stared copying files to the site. The site is currently shown to be at 87% of its quota in SP Admin centre, and above 98% according to the storage metrics, with the threshold set at 80%. If I go to Site Settings, I see a very narrow banner informing me that the site is out of storage space. This is not displayed anywhere else, though, I (as site owner and primary site admin) haven't received any email notifications, nothing is shown outside the settings pages - I can upload another file with no warning. It is now over 72 hours since I started the testing.
If site owners need to go to a settings page to see a warning, it is unlikely to achieve the desired effect and will be disruptive to users when sites do unexpectedly run out of space. Is there something else we can (or need to) do to enable notifications to site owners?

Hi, I would first confirm that the tenant is using Manual site storage limits and verify the actual StorageQuota, StorageQuotaWarningLevel and current storage usage for the affected site. Also confirm that the expected recipients are current site administrators with functioning, licensed mailboxes rather than only a group or an old owner account. After confirming the values, change the warning level slightly, save it, and set it back to force the configuration to be written again. Built-in quota emails are useful, but I would not rely on them as the only operational alert. For important sites, a scheduled PowerShell, Graph or Power Automate report that checks storage usage and posts to an administrator mailbox or Teams channel is much more visible. If the built-in notification still fails, open a Microsoft 365 support case with the site URL, quota values, owners and the date the threshold was crossed.
