## TL;DR

If you want policy-based revocation, use service SAS and plan around the five-policy cap per container. For user delegation SAS, know that the kill switch is the Entra identity, not a policy.

## Steps

1. If you want policy-based revocation, use service SAS and plan around the five-policy cap per container.

2. For user delegation SAS, know that the kill switch is the Entra identity, not a policy.

## When to use

You are seeing this: Account SAS and user delegation SAS do not support them, and each container caps out at five policies. Use this skill when you run into "Stored access policies only work with service SAS, not user delegation SAS".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
