Re: Push mail for this account seems to be blocked on the server
If it says that, then it might really mean that.
It's a real legitimate issue, Aqua Mail uses something called "EWS push notifications" and I've seen some servers not do what they're supposed to, presumably due to a security policy.
Feel free to post the "Exchange push device is" from Aqua Mail settings -> Debug (very end, tapping the ID copies to the clipboard) and I will check the logs of our "cloud component".
This ID is a random hash, doesn't disclose anything about your identity, or feel free to email it to support / at / aqua-mail / dot com.
Finally, if you'd purchased the app for this feature specifically and this is a "no go" for you, feel free to email support / at / aqua-mail / dot com and we'll cancel / refund.
