How to Export All Emails From Outlook Easily 2026
By Impran M N
Whether you're hitting storage limits or switching providers, exporting your full mailbox history protects years of client interactions. This guide covers adjusting your sync slider to capture older mail, then walking through both the classic Import/Export wizard and the newer Outlook export path.
01Adjust your sync settings
Change your offline slider to "All" so older historical emails are included in your export rather than just recent messages.
02Open the Import/Export wizard
In the classic interface, open the File menu and launch the Import/Export wizard.
03Choose your export format
Select "Export to a file" and choose the Outlook Data File (.pst) format.
04Include subfolders
Highlight your root account node and check the "Include subfolders" option so nothing gets left behind.
05Use the new Outlook path if applicable
In the modern interface, go to Settings, then Files, and select Export instead.
06Save and finish
Choose your save location, assign a file name, and click Finish to complete the export.
Frequently asked questions
Why do I need to change my sync slider before exporting?
If your slider only syncs recent mail, older messages may not be locally cached, so switching it to "All" ensures a complete export.
What's the difference between the classic and new Outlook export paths?
The classic interface uses the Import/Export wizard from the File menu, while the new Outlook handles it through Settings and Files instead.
Can I open a PST file on a different computer?
Yes, a PST file can be imported into Outlook on another machine to restore your full mailbox history.
Will duplicate emails cause issues during export?
Outlook includes duplicate item management options during export and import to help handle overlapping or redundant messages.
