To remove duplicate emails, contacts, and calendar items while converting OLM files, use a converter that includes a built-in duplicate-removal feature. Before starting, keep a backup of your original OLM files and review the available matching criteria to avoid accidentally removing different items that contain similar information.
The SysInfo OLM Converter Tool provides a built-in duplicate-removal feature for emails, contacts, and calendar items. During conversion, you can select the available criteria to identify duplicates, such as sender, recipient, subject, and message body for emails; name and email address for contacts; and subject, start date, and end date for calendar entries. Then, add your OLM files, preview the mailbox data, enable duplicate removal, choose your desired output format, and start the conversion. This helps keep your migrated mailbox organized and reduces unnecessary repeated items.
Before processing the complete mailbox, keep a backup of your original OLM files and review the converted data to ensure that important emails, contacts, and calendar events remain intact.
