I have been successfully using Thunderbird for many years. In the last year or so I have been noticing that occasionally one of my sent emails gets corrupted such that the email body starts showing html text and the email subject header is changed to another email header that exists in the same folder but is unrelated to the email body. When I check the corrupted email from the Gmail web user interface, the email is not corrupted. I tried repairing the folder but to no avail. I attach an example of a corrupted email below: --------------M7tGdJQYkZGPsoggrc0M6qR0-- From Content-Type: multipart/alternative; boundary="------------NlJPhaGMpTt1f7wbEHlOvxNE" Message-ID: <4bf83075-b571-4214-921b-09f4582e6e58@jesuit.org.mt> Date: Thu, 4 Jan 2024 10:25:56 +0100 MIME-Version: 1.0 User-Agent: Mozilla Thunderbird Subject: Re: Minutes of SCPC Meeting Content-Language: en-GB To: Charlotte Attard <charlotte.attard@staloysius.edu.mt> References: <AM9PR10MB487111674D307583B8DB6AD3D195A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> <AM9PR10MB487106F96E9E404BDA477808D167A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> From: Stephen Scerri <stephen.scerri@jesuit.org.mt> In-Reply-To: <AM9PR10MB487106F96E9E404BDA477808D167A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> This is a multi-part message in MIME format. --------------NlJPhaGMpTt1f7wbEHlOvxNE Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Yes Charlotte - please proceed - sorry for delay S
