How can Exchange ost files be uploaded to Office 365 mailbox accounts?

[Laurawilliams]

Uploading Exchange OST files to Office 365 mailbox accounts is not straightforward because an OST (Offline Storage Table) file is linked to a specific Outlook profile and Exchange account. You cannot directly upload an OST file to Office 365. First, the OST file must be converted into a PST file, and then the PST can be imported into the Office 365 mailbox.

If the OST file is orphaned, inaccessible, or very large, using a professional tool is the easiest solution. Tools like ATS OST to PST Converter allow users to convert Exchange OST files and upload them to Office 365 mailbox accounts safely and quickly.
