Should I extend the Active Directory schema?

Question

Active Directory

Colleagues, hello. In our outlook, user signatures are generated by a script, the data is taken from ActiveDirectory. The task was to implement signatures in different languages ​​for different users. At first I wanted to expand the AD schema and add new attributes: snENG, givenNameENG, titleENG, departmentENG. Fill them in and rewrite the script to take values ​​from these fields.
But in the process, I came across a list of attributes that Exchange 2013 had already created for me, namely: extensionAttribute(1..15) I didn’t find what they are for on the web, is it possible to write the values ​​\u200b\u200bthat I need in them and pull the info from there with a script?
And if you customize the scheme, how and where to request X.500 OID? Has anyone come across?

Answer 1

Attributes should not be added. Use the standard ones, there are dozens of unused ones.
The ones you mention are just the most relevant
