The Dutch language should not be the cause of this type of error. However, have you found that running the English version of the GroupWise client prevents this error from appearing?
Which version and patch release of the GroupWise Windows Client are you running?
Does the problem happen with all appointments, group and personal?
Does it happen for Reminder Notes or Tasks?
Does it happen for all GroupWise mailboxes tested?
Are you able to access a new (or relatively empty) test GroupWise mailbox with just a few test appointments in it which causes the problem when exported? If so, to help us replicate and identify the reason for the error, can you zip and send the entire Archive To Go portable archive of the test mailbox (which illustrates the error) to support@advansyscorp.com.
By changing the Regional Settings to Dutch, we have been able to reproduce the problem with appointments. An updated version of the Viewer, which includes a fix for this issue, is now available for testing from the url:
You will need to unzip the Archive To Go Viewer application from a2goview.zip, a2goview.exe, and copy it over the existing file in the portable archive’s media _viewer subfolder. If it solves the problem, you may wish to update the master distribution folder, C:Program FilesAdvansysArchive To Go.
After replacing the file the problem is solved in new created archives. By replacing the file a2goview.exe in existing archives the problem is also cured.
