MD5 checksum variance for emails between v2.4.2 and v2.5.0.1


Recommended Posts

Hi all,

I've checked the release notes from 2.4.2 through to 2.5.1 in an attempt to answer this for myself, but I didn't see anything obvious, so apologies if I've missed something.

I have two cases that both have the same PST files as the source data. One was created in 2.4.2 and the other in

When comparing the two cases, the email MD5 checksums do not match for the same items. Reviewing the properties, the calculated sizes are different between the two cases for the emails.

Has the processing of emails changed in some way which would perhaps result in the size of the email being different, and therefore explain this difference in MD5 value?

*Edit* This seems to be for MIME type "message/rfc822" (EML?) as opposed to "application/vnd.ms-outlook" (MSG?) - the latter seem to be fine so far.
