Standardized Access to Common Email and Calendar Formats

**Requested feature**
The feature I propose is to make common email formats (such as .msg, .eml, and calendar files like .ics) readily available for users. This feature addresses the need for users to easily access and manage their email and meeting data in a standardized format. It should clearly display essential information, including the sender, recipient, CC, BCC, date, body, signature, attachments, and mail history for emails. For calendar files, it should include similar details such as meeting participants, date, time, agenda, and any attachments related to the meeting.

**Alternatives**
I have considered the following Manual Export: Users can manually export emails and calendar events, but this process is time-consuming and prone to errors.
