Mail App iOS 13


  • Kopano

    Hi @genesis74,

    The amount of the emails in the inbox might indeed be the issue.

    Did you set to sync all emails? Or do you have some limitation (3 days, 7 days)?

    Manfred



  • Manfred,

    I sync all items and it worked with iOS 12.

    did you have as many items with iOS 12? Did you try syncing less items (e.g. 1 month or 1 week).

    Manfred



  • Manfred,

    with iOS 12 I have approximately the same amount of items in my inbox.
    Unfortunately I am very short on time, so I can’t dig into this issue.
    Btw. other customers, using Novell Groupwise reporting the same odd behavior since updating to iOS 13.x.

    So, it looks like something’s changed in iOS 13. If the device doesn’t send read flag after opening an email, then Z-Push isn’t aware there has been a change.

  • Manfred,

    I asked my Exchange customers, unfortunately all Exchange customers do not see this sad behavior.

    So I assume, for Groupwise and Z-Push, the Active Sync implementation is no fully compliant to the AS specifications.

    Do the exchange customers also have a large (thousands) amount of emails?

    Did you try syncing fewer items like I suggested?

    In this thread https://discussions.apple.com/thread/250700298?page=1 there are several posts that this issue also occurs with Exchange / Office 365 / Hotmail accounts, so it’s clearly not only Z-Push’s or Groupwise’s fault.

  • Manfred,

    my Exchange customers do have similar or even bigger inboxes.
    I assume this issue depends also on version on mail system (AS part).

  • Hi @Manfred,

    correct me if I am wrong but isn’t communication between iOS mail app and MS Exchange based on MAPI while we are relying on ActiveSync with Z-Push and Kopano? At least, I see iOS devices having two accounts, one Kopano account (ActiveSync/Z-Push) and one MS Exchange account (which is assumed to be MAPI-based) with only the AS based account showing the issue leading me to the theory that there is a problem with iOS mail app especially handling lots of messages via ActiveSync - but not via MAPI. Which would have made it basically possible that it is a Z-Push related problem, but it seems to be much more widespread - and as far as I understood what you wrote there is not any misbehaviour of Z-Push noticeable in the logs.

    I don’t know how the default iOS mail app connects to an Exchange server, but I’d say it still uses ActiveSync. As far as I know only Outlook uses MAPI over HTTP to connect to Exchange server (maybe also the Outlook for xxx apps that are available for mobiles).

    If you (or someone else) are also managing Exchange server, maybe you could check IIS connections and how mobile devices are connecting to an Exchange server.

  • Hi @Manfred,

    I still could not determine what the difference is between the mentioned accounts (native Exchange vs. Kopano/Z-Push). But last night Apple released iOS/iPadOS 13.2.3. According to feedback I received as well as tests on my own devices the issue seems to be fixed.



  • Hi,

    I updated to iOS 13.2.3, for two days , mail APP worked as expected (like in iOS 12) unfortunately after two days, mail APP do not show new mails but show “nn unread”, same behavior as iOS 13 release.

    does it mean that new emails aren’t synced to the device? Or are the new emails synced to the device but do not appear in the app?

  • Manfred,

    I can’t tell what happens, I see the count of unread mails, but I do not see the mails itself. Activating the unread filter, seconds later I see the mails.

    that sounds more like the app usability than a Z-Push issue.

  • Hi @Manfred, hi @WalterHof,

    I noticed that the behavior of the Mail app is not exactly as it was in iOS 12.x. Especially, even though email push is activated it seems that the email bodies are only loaded when opening the app. But arriving messages generate the expected sound immediately. To be sure I first have to check with the logs when I have time.

    After the upgrade to iOS 13.2.3 I completely resynced my account (switching off “mail” in preferences, deleting state data with z-push-admin and then switching on “mail” again). I did that on a routine basis for my account just to start over cleanly. But other users did not complain so I assumed that it was not necessary.



  • The update to IOS 13.2.3 solved the main issues with deleting the emails twice.
    There is indeed an delay in getting the notication of a new email and appearing in the folder.
    Pull down in the map app (sync) is working or wait 1-2 sec



  • All my Exchange customer did not see any issues with iOS 13. I guess, Apple tests against Exchange but not against other mail systems. The ActiveSync implementation of Exchange is different to Z-Push, so I assume this implementation differences generates this problems.

    Walter



  • @WalterHof

    Are these bugs resolved? I still got the same issues with the mail app on ios 13.3.1

    Sometimes i need to delete the mail 2 times on the phone before it is removed.



  • Hi,

    it is better but not fully solved. I do not see the unread mails in the inbox. If I then stroke from top to bottom I see the unread mails.
