Mail App iOS 13

Manfred

Hi @WalterHof,

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.

Walter

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

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

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.

Walter

@WalterHof

I still got the issue that i need to delete mails multiple (2) times before they are really deleted.

Do you also still have this issue?

genesis74

Hi @WalterHof,

same here. If I open mail app as soon as email arrives (with sound), I don’t see it in the inbox at first. After refreshing manually it is there. It is also there if I wait for some time before I open mail app after mail is received. Well, one gets used to eat what Apple is serving, but it doesn’t make me happy.

@ckruijntjens
deleting works immediate. I do not see this issue.

@WalterHof

Strange thing? Are you also using ios?

Could you maybe post your sql config? Before my webapp was also slow. Ive changed a setting in sql and now webapp is faster but mail delete on ios is somehow buggy.

The rule i added in mysql config is

innodb-flush-log-at-trx-commit = 2

@WalterHof

One thing i have to notice i have 3 zpush accounts on my iphone

I have only 2 Z-Push accounts on my iPhone .

My MySQL config file:
