When trying to convert a .ost file to .pst (using the web converter) I get this error message:
Oops! An error has occurred.
Error on processing: Unable to read beyond the end of the stream.
I tried multiple different .ost files ranging in size from about 16mb up to 1.6gb and all returned the same error message. The progress bar reaches 100% before the error is returned.
Any help is appreciated.
