Why Outlook OST Files Need Conversion Before Apple Mail
Four official facts explain the gap between an OST file and Apple Mail. PCVITA software closes it on Windows.
- 1
OST Files Copy Your Mail Server Items
Microsoft Support says Outlook Data Files (.ost) are copies of items saved on a mail server and serve Exchange accounts offline. PCVITA tool opens that offline copy and converts the items.
- 2
Shared Folders Grow the File
Microsoft Learn notes that downloaded shared folders live in the local OST file and can make it grow significantly. PCVITA software sets no file size limit, so a large file still converts.
- 3
ANSI Files Stop at 2 GB
Microsoft Learn states that an ANSI OST or PST file is held to 2 GB to prevent corruption. PCVITA software loads ANSI and Unicode OST files alike.
- 4
Apple Mail Imports MBOX From Windows
Apple Support lists an mbox import for messages from a Windows or UNIX computer and names no OST source. PCVITA tool saves your OST emails as MBOX on Windows so the file is ready for your Mac.
Checklist Before You Move OST Emails to Mac
Six checks before your first conversion. Work down the list, then open the converter.
- Copy the OST file to a safe folder so your original stays untouched during the test.
- Check your Windows PC. You need 15 MB of free disk space, 1 GB of RAM (2 GB is recommended) and a 1 GHz processor (2.4 GHz is recommended). On Windows 10, 8.1, 8, 7 or Vista, launch the converter with Run as Administrator.
- Locate the OST file or plan to use the drive search option instead.
- Collect your S/MIME certificate or OpenPGP keys if the OST emails are encrypted.
- Plan how the files reach your Mac. Use a USB drive, a network folder or a cloud drive to carry the saved MBOX or EMLX files across.
- Try the free demo on your own OST file before you buy. Download the OST to Apple Mail Converter demo, scan your file and preview every item.
