Looking for a tool to convert ost to pst online?
OST to PST conversion is often required when either your OST files are inaccessible due to any reason. They are also not possible to import into Outlook since they don’t have import/export support. They are basically offline cached files that contain the copy of your data on servers, so you can also access your data offline.
But if you are getting errors like “Outlook cannot open OST file” or that you deleted your email account from Outlook before syncing the changes to the errors, you need to convert OST to PST. That’s the only way to get your data from the inaccessible OST files back into Outlook.
