EAS on iOS - not staying in sync
Problem reported by Neal Culiner - 5/13/2019 at 4:49 PM

For weeks if not longer I've just seen the iOS mail app counter not refresh properly. I'm using the latest builds of SM Enterprise Edition updating as they come out. Something just doesn't seem right with push sync with EAS. I open the app and it will then refresh the mail account. Sometimes I'll still have a counter of 1 but nothing showing unread in the Inbox. Sometimes no counter until I open the mail app and then it retrieves them, it's just not normal. My gmail app always works fine, it's not my phone. I've tried rebooting the device, going into airplane mode and back out at times. It just seems like something is not reliable with EAS in iOS.

Hi Neal.  iOS doesn't seem to have the greatest EAS implementation.  You can see a list of known issues at this location.

I can't get EWS to work reliably on Mac, I just tried it again and Mac Mail crashed when replying to one message after the switch so I'm back using IMAP there which is reliable. Seems like EAS is not a great solution for iOS. It seems like I should just cancel EWS and EAS and just use IMAP and stop fighting this mess all around.

This is definitely an issue with SM and not iOS or EAS. This has been a problem for about the last two months and I have other users with the same problem, seems like a one off issue, we all have a counter of 1 on the email app when all is showing read in the app. Even with the latest build installed today.

Neal, I agree. I have a mailbox that syncs with EAS with Office 365 as well as IceWarp for a university and they work fine. The only that has issue is the ones synced with SmarterMail. This has always been a problem, for as long as I can remember.

Even new clients who previously were with O365 have reported this very same issue. I even purchased a mailbox etc. with O365 just to test. Copied all my mail over to it, setup a forwarder so that both SM and O365 have the same emails, within a week, my SM sync'd account had 2 folders, each saying there was unread mail, when there was not. O365 was fine. In fact, I ran the test for over 3 months, never had an issue with O365.

I seem to recall EAS working very well in SM15, never had a concern or seeing counter problems back then.

ST kindly open a bug report into this situation. I have a user showing 9 unread emails in their junkmail folder but the folder is actually empty, pull to refresh on iOS does not correct this. There IS a problem with SM.latest and EAS.

Still running latest v15 with a few of the users on EAS. Works very well indeed, including Outlook Android app with combination of SM and O365 accounts.

Some newer SM features might be nice to have, but v15 is *very* stable, so I'm staying put for the time being.

Neal: sometimes I have the Inbox folder still showing unread emails on iPhone/EAS-protocol
For example still showing one unread email, but I already opened/read all emails on iPhone/EAS-protocol.

What helps/resets/corrects this counter for me is to close the iPhone-mail-app, and re-open it, after this action and opening/accessing iOS-native-mail-app again the counter is OK, not showing any unread emails.

Yes, I have that all the time. I think this is an issue on the server side, I'm not going to blame the monster that is Apple and iOS. Something is not syncing properly with EAS in my opinion. Don't dismiss this as flaky EAS is what I'm asking ST.

Again I delete items using Outlook or Web Mail and iOS still shows a counter on the mail app (27) and when I open the app it resyncs. It seems to me SM is having a problem with push/remote notifications from various clients so when mail items change iOS is not getting the notification to resync.
