Problems related to tracking email from Outlook 2013 to CRM

PanzeriElena

We have some problems related to tracking email from Outlook 2013 to CRM 2011.
We have installed the rollup 15 for CRM client for Outlook.

Manual tracking:
1) Customer A sends an email to user X
2) User X tracks email on CRM creating a new case
3) The email from customer A to user X is tracked automatically on CRM
4) User X replies to customer A
5) The email from user X to customer A is tracked automatically on CRM
6) Customer A replies to user X (using the same email already tracked on CRM)
5) The email from customer A to user X is not tracked automatically on CRM, but manually through the function TRACK

Owners and Author of email tracked on CRM:
1) User X tracks the email and create the case on CRM
2) In the case, we have the email tracked, but the owner is user Y and the author is user Z

How can we solve or what we have to check?

Thank you,
