Custom Z-Push sync window
-
Recently we’ve encountered the question of how to handle some very large inboxes and a calendar that shared with everyone and includes quite a few items each day - all while using Outlook and KOE.
The idea was to limit the sync window, using z-push and setting a specific value for the necessary stores/folders but unfortunately there is only a fixed set of constant options that can be used.
Is there a way - without manually editing the PHP code and introducing new constants - to customize the window size?
Unfortunately 6 months is not enough and everything syncs about 20GB of email messages and 32000 events from the calendar. Ideally we’d have something like 18/36 months… since that’s the timeframe relevant to most of the daily work.(I’m also open to any other strategies for very large/shared folders and how to handle them in Outlook without it taking forever each time…)

Hi @Raven24,
Are you referring to https://jira.z-hub.io/browse/ZP-1507 which added the custom sync window for certain folders?
The maximum limited sync period defined by the ActiveSync protocol is 6 months. After that the next value is all. It is not possible to customise that period further without some custom development.
(I’m also open to any other strategies for very large/shared folders and how to handle them in Outlook without it taking forever each time…)
I didn’t quite understand the “taking forever each time” part. Do you mean adding such a folder for the first time in Outlook? Or does it take a lot of time to open items in such a folder after it has been added to Outlook? For working with very large/shared folders webapp or deskapp would be a better option anyway.

Yes, I was referring to ZP-1507, since the calendar an inbox would be shared to every user and this config setting makes it easy to set the sync window the same for everyone.
“Taking forever” in that case was a reference to initial sync, but we’ve also sometimes have other special cases.
Occasionally there might be a delay for changes in a calendar entry to sync up, so the user that edited first will ask another user if they can see the edit (or if people are busy, the same change might happen twice from different people).
Another weird occurrence was that emails were set with the “mark complete” flag (green check-mark next to the message) in Outlook, this might happen for a whole week/month worth of emails. Then later another user, might open Outlook and instead of the flags appearing there, they were being removed from the first user.
None of these happen too often, but when they do, they are really annoying to the users.I’m also not sure if setting up Kopano Archiver might be of help - as far as I understood it’s meant to free resources from the server, not necessarily from the clients. Or phrased differently - if I want the emails and calendar entries to show up in Outlook, they will always need to be synced to it, regardless from what server.
(Unfortunately, we need Outlook for emails, since we’re connected to a branch-specific application, that depends on it. Maybe I can convince users to at least use DeskApp for the calendar…)

Hi @Raven24,
@Raven24 said in Custom Z-Push sync window:
“Taking forever” in that case was a reference to initial sync, but we’ve also sometimes have other special cases.
Occasionally there might be a delay for changes in a calendar entry to sync up, so the user that edited first will ask another user if they can see the edit (or if people are busy, the same change might happen twice from different people).Yes, we had reports that sometimes Outlook takes a lot of time to sync out its changes. It was mostly in large stores.
Another weird occurrence was that emails were set with the “mark complete” flag (green check-mark next to the message) in Outlook, this might happen for a whole week/month worth of emails. Then later another user, might open Outlook and instead of the flags appearing there, they were being removed from the first user.
There were also reports regarding marking emails, but we weren’t able to figure out why exactly it happens.
I’m also not sure if setting up Kopano Archiver might be of help - as far as I understood it’s meant to free resources from the server, not necessarily from the clients. Or phrased differently - if I want the emails and calendar entries to show up in Outlook, they will always need to be synced to it, regardless from what server.
We had plans to add the functionality of opening archives in Outlook, but dropped it as it wasn’t viable: https://jira.kopano.io/browse/KOE-79?focusedCommentId=26803&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-26803. As to your last statement, yes, if you want to open emails or calendar items or contacts in Outlook over ActiveSync, you have to sync them to Outlook first.
