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,

    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.
