We are an IT company who services many companies. Recently, one of the bigger companies brought in a 3rd party consultant who works for a group, and they have their own internal IT who likes to keep a tight grip on everything.
We created an exchange account for this user so calendar sharing could be achieved and events placed for them. I just found out that the password was changed and I no longer have access to that account. I had their internal IT group make the required changes I needed done on the account.
While this is not a big issue, it brings up the question for situations that involve more than one IT group. How do you determine who controls what territory?
EDIT: In regards to password sharing. The issue here is that they do some different ways of managing calendar and email syncing, so the typical normal way would not work, so I had to surrender the password.
