Dynamic External Object error

Microsoft publishes a list of URLs and IPs for Office365. I'm trying to whitelist those URLs. I have connected my TZ350 to the list of URLs as published by Microsoft. One of the URLs is *cdn.onenote.net. The Sonicwall errors on that URL and then refuses to import the rest of the list. I tried to contact Microsoft about this but they are insisting that *cdn.onenote.com is correct and that my firewall is to blame. They say most other firewalls are fine with it. Is there a way I can get the Sonicwall to skip that URL and just import the ones that aren't bad?

DEAG does not support wildcards (see kb below).
If your goal is to use DEAG with O365, please use the network ranges instead.
