710 and office 2010
I've reviewed the notes 66941 and other related ones and 710 gui windows is clearly out of support.
We still have GUI 710 running, but there are plans of office upgrade to 2010. So can gui 710 work in conjunction with 2010 office.
We ran into issues with the BEX Browser and not working correctly with Office 2010 in testing (Using SAP GUI 7.10). We also came across a few issues between downloading to Excel through 7.10 into Office 2010.
If you are going to Office 2010, I highly advise moving to SAP GUI 7.20.
