Thank you all for the effort, but I was able to restore the file without spending my money on solutions that Microsoft itself should offer in a complimentary way.
First, I performed a series of "System Restores" on the PC until I got a date before the problem that was working. This caused the e-mail account to work again, but immediately, the IMAP setup started a new synchronization, creating a new OST file.
Then, I activated the WORK OFF LINE function and closed Outlook 2016. I navigated to the folder where the new OST file was being created, I replaced it with the old 3gb file, and since both had the same name and were created for the same account in the same one Outlook, when reopening the program the file was accepted and the folders all opened.
I then exported everything to a PST file so as to prevent IMAP synchronization from deleting the files.
That's how I saved myself, I was lucky.
NEVER use IMAP again, not before Microsoft corrects this rudeness, or change your security policy with offline backup of that service. I do not agree that I have to resort to paid tools of a "black market" that she ended up creating with this atitute.

Thanks again to all.

All comments anser the Author original question. However the author chose a different path which has nothing to do with his original question which apparent was not so clear beacuse you could understand that reason that the OST could not be accessed is because the exchange server is not available for the user anymore.

Since the experts gave relevant answers for the question - they should be awarded - even if the Author chose a different path.
