- OLM file not detected by the converter: The file path may contain special characters. Move the OLM file to a simple folder like C:OLM and try again.
- PST import fails in Outlook: The generated PST may exceed Outlook’s 50 GB limit. Split the PST output into smaller files using the converter’s split-size option.
- Contacts and calendar items are missing: Some basic converters only handle email. Use a tool that explicitly supports full mailbox conversion including contacts and calendar data.
- Duplicate emails appear after import: The PST was imported more than once. Remove the duplicate import from Outlook’s account settings and re-import only once.
Q: Can I open the PST file in Outlook 2019 or Outlook 365?
A: Yes. PST files are compatible with all modern versions of Outlook on Windows, including 2016, 2019, and Microsoft 365.
Q: Does OLM to PST conversion preserve the folder structure?
A: Yes. A quality converter maps each OLM folder to a matching PST folder, keeping your inbox, sent items, and custom folders intact.
Q: Will the converted PST include email attachments?
A: Yes. All attachments stored in the OLM file are embedded in the output PST during a full conversion.
Q: Can I convert a large OLM file all at once?
A: Yes, but very large OLM files can slow the conversion. Use the split-PST option to output multiple smaller PST files if Outlook performance is a concern.
