Running Qlikview in Edge and usage of Send to Excel (XL) gives 2 errors

[andre_ficken]

Hi Qlikers, 

We are running Qlik (Ajax) thru the Edge browser and when we want to send an object or table to Excel (2019) by using 'Send to Excel' or 'XL' icon in title bar, we run into 2 errors. We are using O365 and Excel does start after pressing the button, but there is a message coming up: Sorry, Excel can't open two workbooks with the same name at the same time. I press OK and then 2 things can happen 1: the worksheet opens with data or 2: a message appears with the file name (a long string of chars and numbers.xlsx) and the text: Excel cannot open  the file 'f010217d322e45dca6aee1598a1a171d.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file. 

Any advise to get this resolved is very much welcome!!

Could you check what happens with other browsers like chrome or firefox? Are any proxies or load-balancers in use? Further happen this for all users? Have they all the same releases from Windows and Office? Are there differences in regard to the exported object-type/size?
