Troubleshoot: Outlook not exporting all emails

For an Exchange account, when exporting to a local PST file, it actually performs exporting in the OST file. If not all the emails are cached to OST file, then it will not export all emails.

To resolve this issue, you need first to cache all emails from Exchange server to local OST file. To do this, go to File > Account Settings, double click your Exchange account. Then, set the “Mail to keep offline” slider to All.
