No, OLM to PST conversion retains the attachments and email formatting when done through a good converter like ToolsBaer for OLM to PST Conversion. The tool converts OLM files to PST without affecting the data quality. All attachments, embedded files, images, hyperlinks, and metadata are the same. It will maintain the formatting of an email, folder structure, along with properties like subject line, date, time, and recipient data. When converting from multiple OLM files or single OLM files, the Tool will export their data into PST as it was in Mac Outlook to provide a safe and accurate migration process every time. Furthermore, this application smoothly runs on Windows OS & Outlook versions (new and older).
