Hi, I want do send a lot of mails via python in outlook (see code above). Unfortunately for every loop outlook wants me to confirm the protection lvl (see picture below). Is there a way to avoid protection lvl or set up a default one e.g. "Öffentlichkeit"?

Answer 1

To set a sensitivity label in Outlook (MSIP) you need to add a user property by using the UserProperties.Add method to an item in the following format:

"MSIP_Label_" & guid_internal_use_only & "_Enabled"

But I'd suggest exploring internals of Outlook mail items using MFCMAPI or OutlookSpy to find the exact solution. Try to set it manually then explore internals using these tools.
