My preferred method to transfer POP messages files to a new profil is manual, without using an add-on: • Copy the ""Mail"" folder from the old profile folder to the new profile folder. • in the new profile set up the first email address as POP account • go to Account settings > accountname > Server-Settings > Message storage > Local Directory and click on the ""Browse"" button (see image) • navigate to the ""Mail"" folder in the new profile, open it, select the corresponding <strong>""pop.xxx.xx</strong>"" account folder (containing the old messages of the newly created POP account), click ""Open"" and restart TB. Thunderbird now should display all folders and messages for this email address. Proceed the same way for your other existing email addresses. </p><p>I can't say whether the import method with ImportExportTools NG is easier or faster than my manual method. For someone not familiar with the profile structures the add-on might help to avoid errors while transferring mailbox files from one to another profile. </p>",Mapenzi,false,0,0
