Just yesterday while checking what I'd get in the conversion of STF loot, I also noticed none of the items that are attached to the couple mails I send from one toon to another appear.

First I checked that it happens in sector space, without direct access to mail (console or freighter).
Then I called in the S.S. Vov'wI which should grant direct access to both sending items and receiving them. Sadly, even when I clicked on the "mail" option on the S.S. Vov'wI's interface, the attached items still didn't appear. I couldn't see the items nor the button by which I could claim them.

Are these mails sent on the live server? you can't retreive attachments on mail sent between servers.

Ah, didn't know about that.

Given that I can see the same mail on both servers made me think I can get to sent items from both servers.

My wrong then.

Yeah, sending items between servers is disallowed so that you can't get an item easily on Tribble and move it to Holodeck.

No matter what, now you don't see that items are attached to mail unless you're using a mail console, on holodeck. Unpleasant, and kinda similar to what I originally posted.

Also, yes, of course, I'd never think I could send anything FROM Tribble. Still, I didn't realise I couldn't get stuff from holodeck ON Tribble (nor even see it's there in the mail).
