Hi Brian B

Thank You for mentioning manual method, but in case of bulk repairing of OST file by manual doesn't make sense. Consume lots of human efforts and time and also not secure to rebuild again with all lost data.

By this, I suggest SysTools OST Recovery Software, repair and recover lost data of batch OST file.

Thanks

Why would you need to be bulk repairing anything? If you just delete the OST file, Outlook will rebuild it. No need to purchase any tools.

I read over your website as well and one thing isn't clear to me... Does this tool fix the existing OST file or just export it to PST?

Hi Brian B

SysTools OST Recovery Software is a multi-functional application,

  • View OST File
  • Repair OST File

Your mention manual method to delete the OST file will work only when the Outlook and Exchange Server are in perfect sync.

Thanks
