Common Errors When Importing MBOX into Outlook

1. “Outlook does not recognize this file type”
This appears when you try to drag a raw MBOX file into Outlook. Convert it to PST first, then use Open Outlook Data File.

2. Folder structure missing after import
A single MBOX file is one folder. If your source has multiple folders, point the converter at the parent directory so each MBOX becomes its own Outlook folder.

3. Special characters appear as question marks
The MBOX may be in a non UTF-8 encoding. Set encoding to “Auto detect” in the converter, or specify the source encoding manually (often ISO-8859-1).

4. PST grows past 50 GB
Outlook limits PST size to 50 GB by default. Split very large mailboxes into separate PST files during conversion using the Split option.

Frequently Asked Questions

Q1. Can Outlook 365 import MBOX directly?
No. No Outlook version, from 2007 through Microsoft 365, reads MBOX natively. Conversion to PST is always required.

Q2. Are attachments preserved during the conversion?
Yes. Every attachment, including inline images and large binary files, transfers from MBOX to PST without loss.

Q3. Will the source MBOX file be modified?
No. The converter opens MBOX in read only mode. The output is a fresh PST file in your chosen folder.

Q4. Which clients export MBOX files?
Thunderbird, Apple Mail, Eudora, Opera Mail, Mozilla SeaMonkey, and several Linux clients all export MBOX.

Q5. Can I import the resulting PST into Outlook for Mac?
Outlook for Mac uses OLM, not PST. Convert MBOX to OLM instead if your target is Outlook for Mac.
