Microsoft Office 3.0 (1992)

Question

I came across 19x 3.5" Floppy Disks with Ms Office labels, date 1992.

7x MS Words 2.0

6 x MS Powerpoints 3.0

5x MS Excel 4.0

1x Setup (last 19th disk)

A bit look on internet, wiki had it as Microsoft Office 3.0 however Mail 3.0 was included.

no details avail anywhere.

As usual, no information available in Microsoft.

Online Microsoft Support claim there was only 9 disks (very inaccurate).

Microsoft Community has no answer available

2 Questions:

How many disks came with Ms Office 3.0 in 1992 ?

Was there variant of Ms Office 3.0 came out without Mail 3.0 ?

My appreciation to anyone knows some facts/details of this product and advise me please.
