Only in the newest version. IIRC in the version that you are asking
about F5 does what it has always done even in OE, just issue an
NNTP LIST command. Note: you would have to do a netcap
trace to see this. It is not something which is even hinted at by
the troubleshooting log. Also, just saying F5 is not very precise.
Context matters, although it is less apparent in WLMail than it
is in OE. E.g. Synchronize newsgroup can only be done while
a newsgroup is open.

It's really pretty simple: Headers gets only headers; the maximum number of
headers depends on the Get ___ headers at a time option and whether
it is checked. If you use a synchronize command you have the additional
effect of being able to download bodies at the same time. (Actually
it is done as soon as possible after the headers are downloaded.)
The main difference between Synchronize New Messages Only
and Synchronize All Messages has to do with headers which were
_previously_ downloaded and with whether a Catch Up has been
done. E.g. if a Catch Up had not been done but headers had been
downloaded using Get 300... then Sychronize All Messages could
try to download more than those 300 as well has filling in the bodies
of those old headers which were already downloaded.
BTW the best way to get familiar with what the functions are IMO
is to use the troubleshooting log and see how the client reacts
to the 211 response to group request.

Regarding headers? None.

A synchronize command doesn't pay any attention to the Get ___
value. It just gets headers and bodies depending on both
your last use of the newsgroup and on your synchronization
criterion for that newsgroup.

I don't think so, I think that is only dependent on the
low sequence number in the 211 reply to group request.

That can only happen by accident of the server never updating
the low sequence number in the 211 reply to group request.

I doubt it. Again, all that would be required would be to remember
a previous 211 reply to group request

You wouldn't care. You would only be reading current messages.
You then would be depending on the care that others were giving
their quoting to understand the context for old threads or just marking
them with Ignore Conversation.

Ha! As with many MS products, if you really want to know how stuff works
it's reverse engineering all the way. ; )
