I made my first tests with Groupwise 2014 and noticed two cases, where the behavior is different from Groupwise 2012.
Environment: POA Version 14.0.0-115243, SOAP Schema 1.04

1) While reading a list of subfolders with getFolderListRequest, the attribute 'gwt:name' is missing for all system folders in getFolderListResponse. Custom user folders have it though.

Example:
<ns2:getFolderListRequest xmlns="http://schemas.novell.com/2005/01/GroupWise/types" xmlns:ns2="http://schemas.novell.com/2005/01/GroupWise/methods" xmlns:ns3="http://schemas.novell.com/2005/01/GroupWise/events">
<ns2:parent>6.GW2014.poone.100.0.1.0.1@15</ns2:parent>
<ns2:view>default peek noDownload noDisplay</ns2:view>
<ns2:recurse>false</ns2:recurse>
<ns2:imap>false</ns2:imap>
<ns2:nntp>false</ns2:nntp>
</ns2:getFolderListRequest>

Response:

2) The function getProxyAccessListRequest always fails with error code 3025, no matter what mailbox i use it on. It seems to indicate a memory issue on the POA server, but i checked it and everything seems ok there.
