What type of account was it? It depends upon who 'owns' the account.
If it was a linked business account (i.e. they paid the licence fee for it) they can recover and access it still just as they could when you worked there - they could log on as you at any point and view your data. When its a business account they own it and all of the data on it.
If, however, it was a free account and you used shared folders (or a paid account you just did shared folders between) then as its your account you should be OK.
