![]() ![]() ![]() Not being able to find an easy way out of my issue via PowerShell I initially thought using Python to parse the eml file as there is nice parser available which does exactly what I was looking for. Issue was being caused by character limit in the subject line which was being broken down to a new line making my filter useless. The above was working while tasting the solution in an interactive session but when I started feeding real production data to the script the parsed data was missing key data I knew was in the original eml file (if you’re working the subject line contained a tag followed by two listing email addresses, so a rather long string). ![]() # Define regex $subjectRegex = '^subject:' # Get eml content $emlFile = Get-Content -Path $pathToEmlFile # Get only relevant data $emlFile = $emlFile -match $subjectRegex My requirement was to extract the subject line of the message as it contained information I needed and, as EML is just like a regular text file, I initially thought I could easily get away with something similar the following: EML an obscure file formatĮML file format is defined in rfc0822 with an extension in rfc1521 defining MIME entities but as far as I know there is no official definition of the file format.Īnyhow EML is the format MS Teams is using to store email messages that are sent to the a team’s address and while retrieving the EML file itself is rather easy extracting any meaningful data from it proved another story. I initially thought this would have been rather easy. ![]() To give you some background I implemented a solution sending notifications to a dedicated Microsoft Teams channel containing some information that needed to be parsed by a script and eventually take some actions. Some time ago I’ve been faced with a challenge, well a file format I should say, I was not expecting parsing an EML file format which, in total honestly, I thought extinct. ![]()
