We did searched a while, but could fine any valid option to export our users mailboxes for example to a .pst file.
We would like to move some of our users to Office365, but we dont know how to do this at the moment.
The IMAP import option via Office365 didnt worked, cause it says that the remote server has errors, but IMAP is enabled in server.cfg
We saw, that there is an option to select all and zip em, so we have a bunch of .eml files, but there is a limit of 30 MB.
If someone has an idea, we would be very appreciate if you could share your knowledge.
