Hi,
I'm using OneDrive for Business connector to save the content of an email from the flow to OneDrive.
The file is created in a plain text form and can be read all right.
Now the OneDrive search does not find the content present in this file.
And when the same file gets uploaded to OneDrive for Business via UI, the search does find it.
It appears that the flow connector creates the file in the form or with metadata that prevents the search from indexing its content. As a file owner and the flow author I cannot see any difference in the metadata of two versions of the file.
