the target address being added or overwritten on contact that GME changed to a user when syncing with the overwrite checked
When doing a directory sync with CMG and there is a pre-existing user that has a object in Groupwise and the Exchange mailbox was created manually, a targetaddress is being added to the exchange account.
To prevent the target address being added or overwritten on contact that GME changed to a user when syncing with the overwrite checked do:
In the connector advanced settings - custom configurations tab
Click ok; save configuration; restart service.
This sets the attributes that are modified when it joins to an existing object in the directory. The above list was taken from my connector configuration. It is basically the list of all attributes mentioned in the <connector name>-Groupwise-ActiveDir-Contact (mail enabled)-person.txt file minus the targetaddress , dn, objectclass attributes. They should verify that the list here is the same as theirs and modify it as necessary. The attribute list is the values on the left hand side of the equal sign in the mapping file.
