Issues with Office365 Exchange Connectivity


for roughly a week I have connectivity issues from Outlook on Windows and Mail on iOS to Office365 via the Exchange protocol. Several times during the day the devices are not able to connect to my mailboxes. Once I deactivated the Wifi and the phones connect through cellular service it works fine immediately. Today I replaced the Cloudflare DNS servers in my router with the ones from Google and the problem disappeared completely.

Can you please fix this issue?

nothing? hmm then i will continue using the Google servers

Hi, can you post results from and the domains that you’re having trouble to resolve?
