By default mail messages ingested into Data Protection (DataMinder) 14.5 through the EMC S1 integration using an EMC SourceOne Office 365 job are not de-enveloped and this results in policy being applied to a journal report and not the embedded message.
FIX:RO90350 (incorporating Integration_14.5_HF0194 and Integration_x64_14.5_HF0195) was introduced to enhances the existing EMC S1 Integration functionality by enabling Office 365 Journal Reports to be de-enveloped and the correct Data Protection (DataMinder) policy applied.
After applying this fix customers noticed instances of mails that appear to have no recipients. Further analysis revealed that the BCC recipient information is missing.
