Whenever my EE phone tries to connect to an EE WiFi hotspot, I get the following error message:

 

Cannot verify server identity: the identity of outlook-cba.office365.com cannot be verified.

 

how do I fix this please?

Then it looks like an Outlook bug.

Thanks. I’ve used outlook on my phone for years, and never had this error. Then I move to EE, and get the error every time the phone tries to connect to an EE WiFi hotspot. It’s fine in all other WiFi networks.
