OnSite

No. I'm using a legid, licensed copy of Microsoft Office 365. And for that reason I find this thing strange and that I have done scans with various antivirus looking for some malware, without finding anything.

And why any Office app try the connection with theese sites?

also 365e.live ....

Every time an Office app (Excel, Word, Outlook, etc) is started, Eset NOD32 shows a popup saying it has blocked access to autodiscover.365e.live site. I've made scannig also with other antivirus without finding any malware or suspicious file. Is it a false positive or a legid warning? Thank you
