Outlook for Mac is a powerful email client, and it is common practice to import .pst files into Outlook for Mac. However, many users encounter issues when importing an ANSI .pst file. While importing .pst files is generally supported, there are some limitations around ANSI (American National Standards Institute) format files. Let’s explore why this happens, the differences between ANSI and Unicode .pst files, and how you can work around this limitation to successfully import PST files into Outlook for Mac.
Why Can’t Outlook for Mac Import an ANSI .pst File?
The main issue is that Outlook for Mac only supports importing Unicode .pst files and does not recognize the older ANSI format.
Key Differences Between ANSI and Unicode .pst Files:
- ANSI .pst Files: These older formats were used by Outlook versions before Outlook 2003. ANSI files are limited to a size of 2 GB and do not support multi-language characters, which means they’re not ideal for non-English data.
- Unicode .pst Files: Starting from Outlook 2003, Microsoft switched to the Unicode format, which can handle large PST file sizes (up to 50 GB) and supports multi-language characters. This format is compatible with the newer versions of Outlook, including Outlook for Mac.
Because ANSI files were used in older versions of Outlook, they lack the compatibility features required by modern Outlook versions, which include Outlook for Mac. This discrepancy means that Outlook for Mac will simply not recognize ANSI-formatted .pst files thus not letting you import it.
How to Determine If Your .pst File Is ANSI or Unicode
When you try to open an ANSI file in MS Outlook throws up the error message like “This Data file could not be imported” or “There is something wrong with this file”; depending upon your Outlook version. However, if you want you can check whether your .pst file is ANSI or Unicode beforehand; here’s a quick way:
- Open the .pst File in Outlook for Windows: Since Outlook for Mac won’t open the file, you’ll need to use a Windows-based version of Outlook for this.
- Go to File Properties:
- In your Outlook application, navigate to File > Account Settings > Account Settings.
- Locate the data file associated with the .pst you’re examining.
- Check File Format:
- Right-click on the .pst file and choose Properties.
- Look at the Format information. If it says “Outlook Data File,” it’s Unicode. If it says “Outlook 97-2002 Data File,” it’s in the ANSI format.
How to Import ANSI .pst Files into Outlook for Mac?
To import your ANSI .pst file into Outlook for Mac, you’ll first need to convert it to the Unicode format. Unfortunately, there’s no native tool within Outlook to convert an ANSI .pst file directly to Unicode, but you can still achieve this conversion with a few steps.
Converting ANSI .pst Files to Unicode to Unicode – Step-by-Step:
- Open the .pst File in Outlook for Windows:
- To perform the conversion, you’ll need a Windows computer with Outlook 2003 or later installed.
- Create a New Unicode .pst File:
- In Outlook, go to File > Account Settings > Account Settings > Data Files > Add.
- Choose the Outlook Data File option, which will create a new Unicode-formatted .pst file.
- Transfer Data:
- Open your ANSI .pst file, then copy all its folders (emails, contacts, etc.) to the newly created Unicode .pst file.
- This process might take some time if the file is large.
- Save and Close:
- Once the transfer is complete, save the new Unicode .pst file.
With your data now saved in Unicode format, you’re ready to import this file into Outlook for Mac.
Importing the Converted Unicode .pst File into Outlook for Mac
After converting your .pst file to Unicode, follow these steps to import it into Outlook for Mac:
- Open Outlook for Mac.
- Go to File > Import:
- In the import dialog, select the Outlook for Windows archive file (.pst) option.
- Locate and select the Unicode .pst File:
- Browse for the newly created Unicode .pst file and select it for import.
- Complete the Import:

Alternative Solution: Third-Party Conversion Tools
If you don’t have access to Outlook on Windows or find the conversion process cumbersome, you might consider third-party tools to help with the conversion. There are several programs available that can convert an ANSI .pst file to Unicode.pst file format.
Final Thoughts
Though it may be frustrating to encounter this limitation with ANSI .pst files in Outlook for Mac, a few workaround solutions can help you get your data where you need it.
