You can share your E-Mails with internal users. Depending on the requirements, different methods exist.
To make E-Mails available to internal users, proceed as follows:
Create a new personal folder to which you will copy or move the required E-Mails.
The users have to subscribe to your shared E-Mail folder in order to have access to the E-Mails.
If another user shared an E-Mail folder with you, you have to subscribe to the shared E-Mail folder in order to have access to the E-Mails.
