Security and Compliance
Andre Ruschel you may refer to Microsoft 365 admin center or Microsoft 365 Compliance Policy to see some log files and monitor some activities of Exchange and other Microsoft 365 services:

However, you will have to define policy to monitor or prevent data lose and enforce it for accounts you are looking for:
https://docs.microsoft.com/en-us/microsoft-365/compliance/protect-information
There are many helpful information there and I recommend you try them out and you may refer to documents where I shared to learn more.
Thanks Reza_Ameri-Archived
I already checked all of these documents.
Andre Ruschel to answer your question, I would say it depends on your scenario, so when you create Audit or monitoring , you could set how log that monitoring stay on, while for other log files, there is no limitation and log files will remain forever unless if you close your Microsoft 365 or request for removal.
