Sender information is missing when accessing via Exchange or IMAP

TGM

Hello everyone,

The following scenario: We have made a Grummonio Community installation for testing and I have connected our users via LDAP. For these users I have imported the mailbox from Kopano into Grommunio. Everything looks good on the web interface and I can see the e-mails perfectly and can access them perfectly.

But when I access it via IMAP or Exchange interface, the sender information is missing from the e-mails. These are exclusively internal e-mails that were written from Kopano. It doesn't matter whether the old user already has a Grommunio account or not.

Any ideas?

Okay, if I migrate the mailbox with the tool "kopano2grommunio.sh" then the mails does have every from informations.
