you will need to translate them, as your command of English is clearly 
MUCH better than my trivial knowledge of French]

I'm not certain what the source of the problem is, but there are 3 
things that I can think of that could cause this:

1. The "archive" folder is not synchronized on your work machine. You 
can either find it in the folder hierarchy of the IMAP account in the 
Sources section of the MailMate mailbox list and synchronize it 
specifically (in the contextual menu or under the regular Mailbox menu)  
or use the menu File->Synchronize->All Sources to synchronize 
everything. If it fails to get synchronized regularly, the root cause 
could be that it is be set to synchronize only manually, which you can 
fix by selecting it and using the "Synchronization Schedule" submenu of 
the Mailbox or contextual menu.

2. The "archive" folder is not understood by MailMate on your work 
machine to be THE Archive folder (a single special-purpose folder) for 
that account, and you are looking at the Archive->AccountName folder in 
the Mailboxes section of MailMate's  mailbox list, which is some other 
folder in that account. To tell MailMate that a specific IMAP folder 
should be treated as one of the 5 special-purpose folders recognized by 
MailMate, select the folder in the Sources section of the mailbox list 
and use the Mailbox Type submenu of the contextual or Mailbox menu.

3. You are not subscribed to the "archive" folder on your work machine. 
Select the account in the Sources section of the MailMate mailbox list 
and use the "Edit IMAP Account" option from the contextual or Mailbox 
menu to open the IMAP Account Settings window. In the center section of 
that window there is an "Edit Subscriptions..." button that opens a 
panel listing all of the folders in the IMAP account and their 
subscription states, both in the server's subscription list and in 
MailMate's own internal list that governs which folders you actually see 
(and which get synchronized) in the Sources section of the MailMate 
mailbox list. This seems to me to be an unlikely cause, since an 
unsubscribed folder would not be missing messages, it would be be 
entirely absent.
