Common Errors When Importing DBX to Outlook 365
You tried to import a raw DBX. Outlook 365 only imports PST. Run the DBX to PST conversion first.
2. Folders missing after import
Make sure every DBX file in the source folder was converted. Each DBX represents a separate folder in Outlook Express.
3. Attachments stripped during conversion
Use a converter that preserves MIME parts. The 4n6 tool keeps every attachment with its parent message.
4. Import to Outlook 365 stops at a single folder
Pick “Include subfolders” in the Outlook import wizard so the whole folder tree comes across in one pass.
Frequently Asked Questions
No. DBX is the Outlook Express format, and no Outlook version reads it natively. Conversion to PST is required.
Q2. Will Outlook 365 sync the imported PST to the cloud?
Yes if you import into an online (Exchange) profile. Items go up to Microsoft 365 over the standard sync.
Q3. Are the original DBX files modified during conversion?
No. The DBX is opened read only. A new PST is created in your chosen output folder.
Q4. Can I convert multiple DBX files at once?
Yes. Point the converter at the Outlook Express mailbox folder and every DBX inside is processed.
Q5. Does the resulting PST work with Outlook for Mac?
Outlook for Mac uses OLM. Use the OLM output option in the converter if your target is Outlook for Mac.
