Greetings community
Currently at my job, our email accounts have been migrated to office.365. We have a procedure in the Oracle database, version Oracle Database 11g Release 11.2.0.4.0, which sends emails. after the change to office.365, no mail arrives from the procedure.
The procedure is indicated in the attached image.

I searched the internet and they mention that the solution is using wallets and authentication certificates, but not even my 365 license provider has given me the scope of the certificates. Can you help me?
