I am struggling to find anything anywhere from Microsoft to acknowledge this is being fixed, and I do think it's more of an Excel issue than Dynamics, but any advice is greatly appreciated.
I've posted this question in the normal MS community: (http://answers.microsoft.com/en-us/office/forum/office_2016-excel/unable-to-refresh-data-in-excel-2016-when/1b8d9657-6c53-419b-a260-19bcccd4a9e6?tm=1473176623890), and one relating to Excel IT Pro: (https://social.technet.microsoft.com/Forums/office/en-US/6e0f1cd1-ea3c-45eb-b16b-56d7c06f9e03/unable-to-refresh-data-in-excel-2016-when-exporting-dynamic-worksheet-from-ms-dynamics-crm-2011?forum=excel) but alas no light has been shed.
I am aware of the workaround here : https://support.microsoft.com/en-us/kb/2556284 but it's just not feasible to expect our clients to use this every time they open the document.
Does anyone know whether Microsoft are aware of this issue and are working on a fix? The support ticket raised with them did not really shed too much light on the situation and I was directed here.
Many thanks in advance!
