My customer is a global company, with a fairly complex AD forest. I have been working with Unity 5 and Unity 7 within EMEA, so have consequently had to extend the schema to support these.
My customer currently uses Exchange 2003 but the US team have now informed us that they intend to extend the schema to support Exchange 2007 for the US sites.
My question is, would this cause an issue? I've been doing a bit of searching through CCO and my impressions are that this should not cause any problems, but I just wanted to ask the experts in case I missed something.
They intend to do schema update this weekend !
