we are using a OPEN-XCHANGE 5333 version and i am trying to get
OXlook working. I can create and delete calendar entries well in Outlook
(tried in 2000 and XP), but i can NOT edit an existing entry, even not
an entry i have created on my own only a minute ago.

There shows a little info, that the information can not be written
in that area.

Does anybody know a solution for this problem?

Thanks and kind regards
