We're testing a Win 7 machine with Office 2007 on our GW 8.0.1 HP1 system and have come across a strange issue.

If we open an existing GroupWise Excel 2003 document, edit it and then choose Save As -> New Document back into GroupWise the document which goes into GroupWise has been given an xlsx document type (Excel 2007) even though the document is still in 2000/3 format. This means that the document fails to open as it is in the 'wrong' format for Excel to understand.

If we edit the DMS document properties and change the extension to xls from xlsx then the document will open fine.

Is this a known issue? Is there any workaround? At the minute I've asked the user to use the copy document function in GroupWise before opening the document but when Office 2007 is rolled out properly this is bound to come up again.
