Having trouble importing all my emails from outlook.

I just started using eM Client and am impressed so far.  However, I am not able to import all my email from Outlook.  I have tried several times and each time it only imports about two months of emails to a specific date each time.   I of course have a few years of emails that need to be imported.  Can anyone help me with this?

Hello Lou,
do you import your data from Outlook directly or from a PST file?
Are some of the not imported mails saved locally or archived?
What version of eM Client are you running currently (Help>About section)?


Thanks Olivia.  I have tried importing both ways, with the same result.   I have never archived any of my email.   And finally, I am using v 6.0.24144.0  .   Thanks again.   Lou
