Hi @lea-kathrin gleissner , Thanks for using Microsoft Q&A Platform.
According to the form recognizer quotas and limit, not sure about the model you are using but suppose the model has Free(F0) tier -500 pages limit. If you exceed the free (F0) pricing tier's limit of 500 processed page, an error message is throwed. Money is not charged. In addition, the error message returned by the resource will indicate how many days / hours remain until the quota is reset for the next month.
To use your Azure Student budget, you can upgrade your account to the Standard pricing tier. The Standard pricing tier allows you to process more pages and provides more features than the free tier. To avoid the time delay of the free tariff, or if you need to use the resource right away, you can upgrade to the standard (S0) pricing tier or submit a support request to increase the monthly training limit.
For pricing details, you can visit here: https://azure.microsoft.com/en-us/pricing/details/form-recognizer/
I hope this helps. Let me know if you need any further information.
Regards,
Vasavi
