Why the Exchange server access is not supported any more since the April Update Office 2016 for Mac 15.21.1!
Since 1998 I have been used an Business version for Mac. The main argument was the use of the exchange server. The version of 2011 lost this capability already in end of 2013. From 2014 I used then on recommendation of Microsoft Office 365 for Mac. Since the last update no access to my companies exchange server is possible. The installation of toehold version doesn't help either! Because the the older version can not open the user date base. Has Microsoft lost its capability to develop a proper software? Otherwise I have to switch to another office software what is really working!
