we are using the open exchange (7.8.4) together with our mail server (cyrus 2.4).
We have some shared mail folders.
Problem: When a user adds me (my account) to access some subfolder, the account can be
selected and added to the subfolder, BUT when the list is edited a second time my name is replaced
with OXADMIN ...
On the Mailserver the subfolder shows correctly my username.
I made a dump (listuser --csv ...) and checked the oxadmin entry. But everywhere oxadmin@ is set as
mail address. Only under Guipreferences it occurs one time.

Any idea why my username is substituted with oxadmin ?

Can I undo this substitution ?

Bye, Peer
