Hi,

i have Outlook for Mac 2011 w/ Exchange 2010 and was working perfectly till i update Yosemite to 10.10.5 or Office Update 14.5.4...

Connection stopped, Exchange is requesting password and after entering it nothing happens...

if i tried to send an email it returns with -17797 Error code...

i rebuilt the DB, change the main Identity, deleted the account and even reinstalled the office without any success...

Mac Mail App, Outlook Web Access, iPhone all are working Normally..

can anyone assist?
