Great question. I had to dig, but
I still did not find the exact place you would do this. I will explain
what I did find, which is at least a clue.
The Mail file navigator is comprised
of an embedded outline on a page displayed in the context of a frameset.
The relevant elements are called:
Frameset: MailFS
Page: NotesMail Picker
Outline: NotesMailOutine
However, there is also some Java code
running in the client that controls the expansion and collapse of certain
navigator items. And the mail db also is a "composite application",
with unique additional design elements to give it more complex functionality.
I tested every combination of embedded
outline properties on the NotesMail Picker page object, as well as the
NotesMailOutline outline entriesf. Nowhere did I find a property
or checkbox to auto-expand any of these links or categories. In summary,
we cannot control the automatic expansion of the Archive link/category
via the Domino Designer client. Thus, it must be part of the Notes
client Java code OR the composite application portion of the mail file.
I also tested by expanding every possible
item in the mail navigator, closing the db and reopening it. The
only nav items that stay expanded (because I have my launch options box
checked for "Restore as last viewed by user") are the views and
folders. So it seems they are treated differently than the "Other
Mail" and "Archive" links.
Within the Composite application elements
of the mail file, I did see a Notes Mail navigator object, but did not
determine a way to edit this for auto-expansion.
I found something similar in the contacts
db which also has a similar construction for the "Other contacts"
link. I believe that this works the same way as the "Archive"
and "Other mail" links in the mail db.
I also found out that there is a (Java
code) class called CSINavControlProvider,
which builds the local contacts (names.nsf) navigator, including this "Other
contacts" link in it. I would imagine that there is a Java outline
property to force auto expansion, but I'm just not sure. And I'm
not sure which .jar file contains that class. I also was not able
to locate the related .jar file used for the Notes mail outline. Either
way, you'd have to be a decent Java developer to edit this, if you could
find it.
I did not locate any internal enhancement
requests, so if this is an option you would like to see in the product
(at least a way to designate if you want it one way or the other via a
client or mail preference), then I would encourage you to open a PMR and
we can get that enhancement created for you. I found an internal
SPR related to a display issue with the archive link, but there were no
details about where this particular code resides: SPR

Not sure if this helps at all.
If I learn anything further, I will
definitely post it here.
