Invio, ricezione e organizzazione della posta elettronica in Outlook sul web per le aziende
Hello Matteo Donato,
Good day!
Thanks for posting into our community.
According to your description, I'm sorry to hear about the issue with your emails.
Recovering emails from the second-level trash can be challenging, it seems not feasible for an end user to achieve it.
Nevertheless, it is best for you to contact your organization's IT administrator to restore it back for you - Ripristino delle cassette postali in Exchange Online - Exchange | Microsoft Learn. Either follow the instruction from the official document or run a PowerShell command will get your deleted items back.
