I'm moving hosting and need to move the emails stored with the old domain and hosting. The hosting I want to transfer from uses Open-Xchange for its webmail and the hosting I want to move to uses Horde for their webmail.Is their an automated way from inside of the Open-Xchange webmail? Is there a way I can do it from inside of Outlook or Mac Mail?
Export emails from Open-Xchange webmail and import them to Horde webmail
email;webmail;openx
With Outlook or any other IMAP client you could simply connect to your mail server,  Then pull the emails to a locally created profile (off the imap server).  Then connect to your new email server and pull them again to its directly.  Based on number of emails this process will TAKE A LONG TIME.
