John I understand that you have submitted the access form and got the approval for Azure OpenAI use.
We are sorry for the inconvenience caused.
I have checked internally on this issue and below is an update.
The subscription plan Azure for Students is no longer allows for Azure OpenAI use.
Our team is working on getting this communicated to avoid any confusion and inconvenience.
As mentioned in Azure account requirements, you can get an Azure account for free and you'll get some free Azure credits to get started to ensure Azure OpenAI deployments are successful once your request is approved.
Hope this helps. Do let me know if you have any further queries.
