I'm trying to access data from Outlook and can download files from exchangelib with a password. But I'd like access without a password. Do we've any alternate for this stuff?
An alternative to "this stuff"? Meaning an alternative to security? No.
The best you can do without credentials is to use Outlook Object Model on a machine where Outlook is already installed and configured to access the folders and messages from a mailbox in the configured local profile.
Is possible to retrieve data and download files from outlook without password using ExChangeLib (EWS)?
