How can i import Emails into SuiteCRM?

Hello Guys,
I have difficulties in importing Emails from Outlook into SuiteCRM.
When i click on the import function in SuiteCRM ian error message appears. I don’t know where the problem is.
I want to mention the fact that the Email account used in SuiteCRM is not the same as the Email account from Outlook (where the Emails i want to import are found ). I don’t know if this the reason .
has someone faced this problem Already ?
