How to Open Inaccessible OST Files with Stellar Converter for OST?

An OST file becomes “inaccessible” due to large size, corruption, or other factors, such as sudden power cuts, improper Outlook/system shutdown, malware or virus attacks, bad sectors in the hard drive, conflicting add-ins, interruption in the network, human errors, etc. When the OST file becomes inaccessible, you lost access to your emails and other mailbox items stored in the offline outlook data file(.ost). 

However, the major problem is that you can’t open an inaccessible file directly in Outlook. This is where an advanced OST to PST converter software, such as Stellar Converter for OST comes into the picture. This software helps you open and convert such problematic OST files into PST, which you can easily import into Outlook. 

Stellar Converter for OST is a handy, multi-feature program for converting inaccessible, orphaned, or encrypted OST files into PST. The software can convert Outlook OST files into PST and other supported formats, such as MSG, EML, RTF, PDF, and HTML with high precision.
