I need to generate new Attributes for an Active Directory setup on a server
I have no problem using mmc to access the AD Attributes editor
When I create a new attribute, I am asked to create a new Unique X500 Object ID

I have the vb script from microsoft but I need to know exactly what to enter in the box:
According to the script, my root is 1.2.840.113556.1.8000.2554...............................714634

Do I just append to the end of this ?

You can use the OID entered from running the Microsoft script, or you can also append some additional sub-nodes to the end if you have a case where you need to create a structure.  Here is a good article on it:

http://tomislavtasic.blogspot.com/2014/01/extending-active-directory-schema.html

In their example, they just used what the script/tool returned.  You can also put .1 on the end for your first attribute, or .2, etc., or

.2.1
.2.2
.2.3

...etc. if you are creating multiple new attributes all belonging to the same 'category' of things.

Most examples just use what the tool returns directly.  And NOONE explains this very well as you have found !

Do I need to need to link the attribute to a user class or can I just use it as it is (from the AD attributes  field)

I've never had a custom attribute not linked to a class.  I suspect that you can however still use it, but you would have to have your own code to update it.  But why would you not want to link the attribute to a class (or classes ?)

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

I want to be able to use the new attribute in the advanced view of AD and add some data to it
This will then be used a s a dynamic file in exclaimer signature manager
There is no reason why I would not link it to a class but I was wondering if it was necessary to do so

I assume that if I want to use it the way I describe I would link it to a user class

Yes, I would like it to the user class.  I think (not sure) that unlinked attributes are available to all classes, it something like 'usncreated' for example.
