I downloaded GainTools OST to PST Converter because I was having trouble with corrupt data of one of my work files. This file was really important, and I had to recover the information as soon as possible. I tried downloading other software, but they didn't work. A friend told me about GainToools OST to PST converter, he had a similar problem, and he used this software with success. I decided to give it a try and was impressed by this tool. This software supports multiple languages and is free to download. 

The interface is quite easy to use, and it will convert just about any corrupt OST file into a PST file. GainTools is especially great for Exchange users because it can safely repair all Exchange mailbox objects and retrieve your data. No doubt, this is a lifesaver tool. You can also convert encrypted OST files into PST files. This is also really helpful; the tool has backward compatibility and works with older versions of Outlook like 2003, 2002, and 2000 versions. Using GainTools, you can also preview the items of an email and get a glance at the converted mailbox. This feature is great to save you time and make sure you converted a file. 

I would give this software a rating of 5 out of 5 because not only its extremely useful but its a free tool You can do just about anything using this tool, export files to office 365, convert files from OST to PST and even convert encrypted files. This tool is a must to work with MS Outlook. It will save you a ton of time and headaches.
