Weird: z-push-top shows a connection from an MS Office365 IP using my user name!
-
Hello,I am testing my freshly installed Kopano server with different clients on W10, iOS, etc. .
On my virtual W10 machine I configured OL2019 and Windows Mail as Activesync clients of my Kopano server. They are workig well, this is good news.
The bad news: I noticed that there is a connection from an MS Office365 IP address (52.97.140.229) to the z-push service on my Kopano server. See the attached screenshot.
It remained in connected state even I shut down W10, but when I rebooted Kopano server it did not come back.
Then I turned W10 on (OL and Windows Mail not started), watched z-push-top and turned on logging on our office gateway. Soon after I noticed https traffic between my W10 and another MS IP (52.114.159.32) then the another IP described above connected back to z-push service on Kopano server.I don’t know why it is? I do not have any MS account configured on my W10 machine. Is this a proxy, or what? And who asked MS to provide this proxy for me?
Sorry for this long post and sorry for my English, I tried to be as clear as I can.

This is a known situation for example with using Outlook for iOS and Android.

@bob4os Wow! Thank you for the information.

@jacsa This morning I blocked the MS IP address space on my Kopano server and iOS Outlook client stopped working. Mail clients on W10 are still working, so the only GDPR problematic client is MS Outlook mobile app. We can live without it :-) Thank you bob4os!

You’re welcome
I read about this some years ago and I will never use that app…
