Outlook 20123 - unnamed.unk attachments

I restored an Outlook folder for an end user, but all attachments on emails in that restored folder show unnamed.unk

What? Why? Where? How?

Could you please provide screenshot for the same?

A .unk file stands for unknown file. It is created in email attachments or while uploading or downloading from Web. This unname.unk file is generated when the file is not properly converted or processed during the transmission. Exactly, there is no way to read these files. Because file may be corrupted or may contain unreadable contents. Also, there are chances for, file to be Virus affected.

The only option available is, if you know the original file type, then rename and save the file with primary file extension and try to open it using the corresponding program.

Hope this helps you
Thanks & Regards,

Hi Scotch Tech,

As SysTools said, .unk is an unknown file that does not have a file association; may contain file contents from an original file that was unrecognized by any program; created typically as a default extension for a corrupted or unknown file that is found in email attachments or downloads from the Web.

It sounds like a botched restore attempt where the data was either corrupted before or during the restore process. I would try to restore again to see if the same result occurs.

How are you restoring and what application are you using to restore the folder?
