Yes, there is a simple solution that allows one to batch-convert OFT files. The main difficulty of working with OFT templates lies in the fact that they work only for Microsoft Outlook, and it takes much time to deal with or convert many templates manually.
One manual solution is to open every template in Outlook and save it in the desired format one by one. But that becomes difficult when you have multiple OFT files.
Another more practical option is to use a utility that implies batch processing. For instance, the Softaken OFT Converter utility makes it possible to add and convert multiple OFT files at once. This allows exporting a mass of templates in formats like PST, MSG, EML, or HTML without repeating the operation for each item.
