How can I get employees to use ZOHO CRM? - (The hardest thing to implement in CRM)

I recently joined a property management company and I see the value of using ZOHO CRM because at any time we have over 100 open cases. I have been using ZOHO CRM and it has been working better then the old case management system, which is writing messages down on yellow stickeys or phone memo notes. The president see's some of the value of ZOHO CRM and so do the other employees, but whenever they get a call or issue, they give it to me to log in to the CRM.

Clearly data entry is taking away from time on more productive things, like finding new clients and managing cases. I gave everyone login credentials, but they seem overwhelmed by CRM. They are used to using the Quickbooks for logging accounting and anything important they would create a note in Quickbooks. Creating cases seems to be a much more time consuming process for them and they simply pass it on to me which slows me down and the entire organization because everything has to go through me instead of being multitasked through ZOHO CRM.

When they do log a case, they leave out so much detail, their notes are practically useless. They don't understand that we need quality data because you never know when your going to need that data and for what in the future.

I would like to know how other people have effectively implemented a CRM system into their organization, and effectively means that other people use it to log every point of contact and every business action they take.
