I originally installed eM Client about 3 weeks ago on my old Satellite Pro M70 / WinXPSP3 laptop, and then imported all my email folders (dbx) from Outlook Express .
I subsequently (about 1 week later) also installed eM Client on my new HP Probook 450 G1 / Win 8 Pro laptop, and transferred the eM Client data files from the old laptop, by restoring the backup of the eM Client data files made on the Sat Pro M70 laptop, to the eM Client on the new HP ProBook 450 G1 laptop.
Today, on the new laptop, I noticed the duplication very old e-mail messages (up to about 10 yrs old) in many of the old Local Folders of my POP3 e-mail account, and also some of the newer e-mails messages in newer Local folders.
I checked the e-mail Folders in my POP3 account on my ISP’s webpage, and there are only about 5 very recent e-mail messages in the Inbox folder, so the duplicates cannot be coming from there.
It would appear that duplication of many of the e-mail messages had taken place during &/or after the importing of e-mail from Outlook Express 6 to eM Client on the Old Sat Pro M70, because the duplicate e-mails do NOT show up in the respective Outlook Express POP3 account e-mail folders, but do show up in eM Client on the Old Sat Pro M70 laptop.
I have tried restoring 3 different eM Client data file backups, and have also re-installed eM Client twice on the new HP ProBook 450 G1 laptop, but it makes no difference; the duplicate e-mails are still there.
I hope that this is not an on-going duplication process.
I would greatly appreciate if anyone could tell me what could be causing this problem, and how to resolve it.
Thank you very much
