Issue InboundEmail.php

if (!empty($contentType) && strtolower($contentType) === 'text/plain') {
                $email->description = $this->getMessageTextWithUid(
                    $uid,
                    $contentType,
                    $structure = null,
                    $fullHeader = null,
                    true
                );
            }

            $email->description_html = $this->getMessageTextWithUid(
                $uid,
                $structure->subtype,
                $structure,
                $fullHeader,
                $clean_email
            );

Possible Fix

if (!empty($contentType) && strtolower($contentType) === 'text/plain') {
                $email->description = $this->getMessageTextWithUid(
                    $uid,
                    $contentType,
                    $structure = null,
                    $fullHeader = null,
                    true
                );
            }

            $email->description_html = $this->getMessageTextWithUid(
                $uid,
                $contentType,
                $structure,
                $fullHeader,
                $clean_email
            );

Steps to Reproduce the Issue

Go to Inbound E-Mails and import to any related record. This will lead into a runtime error, because the given content is null. I used IMAP import and OFFICE365
