A user posted on the CRM forum a question asking if there was a CRM 2013 handbook
Now there isn’t a handbook that’s for sure but there is quite a lot of information but it’s in separate locations and a bit confusing as to what you will need.
So there isn’t a CRM 2013 user guide but what have got
Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online Implementation Guide
Microsoft has a CRM customer centre which is a great place to start and this has ebooks, videos and online articles to help get you started and I will admit it’s not a PDF you can print out but really once you have got use to CRM I don’t think you would need to print it out and think of the tree’s people
http://www.microsoft.com/en-us/dynamics/crm-customer-center/default.aspx
and in there they have some videos and ebooks/pdfs and top tasks
www.microsoft.com/…/get-started-best-bets.aspx
they do have a special section for ebooks, although they are more like short guides rather than a book
http://www.microsoft.com/en-us/dynamics/crm-customer-center/ebooks.aspx
CRM 2013 eBooks
eBook: Change a business process
eBook: What’s changed in this version?
There is the Training and Adoption kit for CRM 2013
which seems to show the same details in a slightly different way.
