Method to return body text in case of html email
getBody() returns the plaintext body, if available.
Otherwise you can use getBodyHTML with JSoup (https://jsoup.org/) to convert HTML to plaintext.
The fix of seek method when using byte array in order to not download file and save it on local disk
What is the issue you are running into specifically?
If you want to read PST files without fully downloading to disk beforehand you will find massive network performance overhead, for example 10 seconds compared to 5 minutes.
The trick is to run multiple "S3 Byte-Range Fetches" in parallel (https://docs.aws.amazon.com/whitepapers/latest/s3-optimizing-performance-best-practices/use-byte-range-fetches.html).
As far as I know java-libpst is not designed with this use case in mind. It's possible though.
The fastest way to solve your issue would be to download locally. Even better, if you can move your code to where the file is located the whole network issue would be solved.
Worth mentioning is mounting an S3 bucket using FUSE locally but I have not tried it personally so don't know how it performs (see https://github.com/s3fs-fuse/s3fs-fuse).
