I want to use AzCopy to copy a blob from account A to account B. But instead of using access key for the source, I only have access to the Shared Access Key. I've tried appending the SAS after the URL, but it throws a 404 error. This is the syntax I tried

```
AzCopy "https://source-blob-object-url?sv=blah-blah-blah-source-sas" "https://dest-blob-object-url" /destkey:base64-dest-access-key

```

The error I got was

```
Error parsing source location "https://source-blob-object-url?sv=blah-blah-blah-source-sas": 
The remote server returned an error: (404) Not Found.

```

How can I get AzCopy to use the SAS URL? Or that it doesn't support SAS?

**Update:**
With the SourceSAS and FilePattern options, I'm still getting the 404 error. This is the command I use:

```
AzCopy [source-container-url] [destination-container-url] [file-pattern] /SourceSAS:"?sv=2013-08-15&sr=c&si=ReadOnlyPolicy&sig=[signature-removed]" /DestKey:[destination-access-key]

```

This will get me a 404 Not Found. If I change the signature to make it invalid, AzCopy will throw a 403 Forbidden instead.
