I was asked to merge 2 archive databases. But I know from previous actions when I copied mails from one db to the other that it isn't as easy.
If I copy mails from db1 All Documents and paste them into db2 All Documents then the mails appear there and the sent mails appear in the Sent folder.
But when I open the Inbox I can't see the received mails.
And when I after that copy the mails from db1 Inbox to db2 Inbox I have the received mails duplicated in the All Documents.
What's the correct way to merge 2 databases?
