Folder redirection failing under Citrix 1.8

I am migrating a number of laptop users from Notes 4.6.x to Notes 6.5. These clients are running on Windows 2000 & Windows XP. They also have access to a Notes 6.5 client through a Citrix 1.8 environment. I’ve installed the application on the C: drive but set it to access their home directory H:notes\data\notes.ini file so that they have the same settings locally and through Citrix. The home directory is set to be available off-line so that they can use it remotely.

Working on the local version of Notes all is fine and they can see redirected folders, access the files and replicate as usual. Once inside the Citrix environment any attempt to access the redirected folders results in an error message of ‘The parameter is incorrect’ although the folder appears in the ‘Open Database’ list. The folder redirection worked fine from the Citrix environment using Notes 4.6

Has anyone else had this issue and is there a solution out there?
