Someone recommended OST Viewer Tool at http://www.ost.viewertool.com/ as an ost viewer software that could also repair my ost files. I wanted to know if anyone used this software before and if they did tell me how effective it is.

Hi,

The OST Viewer is a 3-rd party tool. Based on my research, here are some reviews about the tool:

Additionally, we can use Scanpst.exe to repair OST file:

To move your OST file PST file, you should use OST To PST Email Converter Tool by Recover Data. This software is responsible for recovering and repairing orphaned and lost .ost files and convert it into your .pst file format. Demo version are available on our official website :-  http://www.convert.osttopstconverter-tool.com/

If an .ost file becomes unreadable due to corruption, one should use OST recovery software to fix corruption. I would like to recommend Outlook Repair Toolbox to fix corrupt .ost file and to recover mailbox items from http://www.pst.repairtoolbox.com/

It restores maximum possible data from corrupt .ost file such as: email messages, calendar, contacts, appointments, tasks, journals, notes, etc. It saves all the recovered data into different formats of MS Outlook and Outlook Express, such as: MSG, PST, EML, DBX and MBOX and Archive (EML, VCF, ICF and text) format.

Meanwhile, users of Outlook 2003 working with higher versions of Exchange or vice versa are suggested to make upgrades to overcome compatibility and consistency issue. The data becomes more highly vulnerable to getting damaged with virus and other damaging issues when Microsoft stops offering updates. To fix such issues and recover data from corrupted OST file an appropriate OST converter application is required. 

You can use OST to PST Conversion Software for the recovery of your Outlook ost file as well for converting OST to PST successfully. Go to http://www.osttopsttool.org and http://www.convertosttopst.org to know more about the application and download the demo software.
