If the OST file is not syncing, it means the OST file is inaccessible. This could also mean the mailbox has been disabled or removed from the server. If the OST file is inaccessible, you can rebuild the file and download mailbox data from the server. If the mailbox is removed from the server, you cannot rebuild the OST file. You can use Stellar Converter for OST to extract mail items from the OST file. Then you can export them to a PST file, your Outlook profile, Exchange Server, or Office 365.
