IOS client telling that it can't connect to Exchange, works on Android
Hi, got a customer, where we get error when running SfB client on the Iphone 7 and on 6S (all Iphones) when they start up the Sfb client, it can't connect to Exchange. And we get no calendar or when...
How mail is set up on the device is likely irrelevant here. S4B uses the Exchange Web Services interface to Exchange Online or Exchange on-prem to pull that data. It's possible the iPhone client isn't successfully handling the autodiscover for the user (this usually happens when the SIP doesn't match the Primary SMTP). It's tough to say why Android would work and iOS wouldn't. I'd suggest manually configuring the Exchange Web Services URL on the S4B on IOS and see if that corrects the issue. (settings -> My Credentials -> Exchange)
If that works then you have to chase down with the iOS side isn't autodiscovering the EWS settings.
Hi, I have asked my customer to try this. Will Get back with some update later
