I'm trying to change the home address of an entry in my personal address book... I use the following code.

(abe is of type AddressBookEntry6)

abe.Fields.Item(fieldname, FieldTypeConstants.egwString).Value = value;

However, I get an error message "Unable to set field value, Address Book is read only".

Any idea why? The address book is not read only: I can edit the address in Groupwise without problems...

I'm used in using MultiLogin with MultiLoginAddressBookSuppot set to TRUE.
