Differences between V5.2.3 V8.2.4

Hi Kenward,
Thank you for reading and answering.

I am not searching inside Outlook
I store all my emails out of outlook, as *.msg files.
I work in a small company and this way we can share email data.

Attachments column only works into Outlook.

5.2.3. version was capable to index files extensions attached to msg files.

I have made more tests.

I have an msg file stored.
This file, has an xlsx called "horas de maquinaria" attached.
The xls file has the word "Ayuda" written in a cell.

If I type "ayuda" on the main search field, X1 finds this word in the xls file attached to a msg file.

But if I write "horas de maquinaria" (xls filename) in mail search field X1 does not find the msg file.

It is not working well
