Microsoft Whiteboard – Boards intermittently fail to load, disappear, or return server errors (Correlation IDs included)

Subject: Microsoft Whiteboard – Boards intermittently fail to load, disappear, or return server errors (Correlation IDs included)

Message: Hello, I am experiencing a serious and persistent issue with Microsoft Whiteboard on my account.

My Whiteboards appear briefly, then disappear, fail to load, or show “Submitted for processing…” indefinitely. When I try to open a board directly, I sometimes receive an error page:

“Παρουσιάστηκε κάποιο πρόβλημα – Αντιμετωπίσαμε ένα άγνωστο σφάλμα” (“Something went wrong – We encountered an unknown error”)

Here is one of the error details shown by the service:

• Whiteboard Correlation ID: [Moderation note: PII removed]
• Timestamp: 2026‑03‑30T10:15:08.520Z
• URL: https://whiteboard.cloud.microsoft.com/me/whiteboards/… (whiteboard.cloud.microsoft.com in Bing)

The issue occurs even after:

1. Full sign‑out from Microsoft Edge
2. Clearing all browser data
3. Signing in again with a fresh session
4. Using only one Microsoft account ([Moderation note: PII removed]@gmail.com)
5. Trying multiple browsers
6. Trying InPrivate mode
7. Successfully authenticating with the new Microsoft Passkey

The problem is intermittent:

• Sometimes all my boards load normally
• Other times they all fail to load
• Some boards show infinite loading circles
• Some boards cannot be opened at all
• Thumbnails remain stuck on “Submitted for processing…”

This strongly suggests a backend service issue with Microsoft Whiteboard affecting my region or my account.

My details:

• Microsoft account: [Moderation note: PII removed]@gmail.com
• Region: Attica, Greece
• Device: Windows 11 PC
• Browser: Microsoft Edge (latest version)
• URL used: https://whiteboard.cloud.microsoft.com (whiteboard.cloud.microsoft.com in Bing)

Please investigate this issue on the server side. I can provide additional Correlation IDs or screenshots if needed.

Thank you.
