Outlook suiteable as a kopano fat client?

Hello,

just wanted to ask, if Outlook is really suiteable as a fat client for kopano and if someone can confirm a smooth working progress with many emails.
I migrated an old MS SBS Exchange to Kopano, but the users can’t work with Outlook as it’s getting stuck on moving a large number of mails from one folder to another as well as it crashed directly after switching folders within few seconds after start.
KOE doesn’t log any problems, it just stops logging if Outlook hangs.
Unfortunatelly those users can’t move from Outlook to DeskApp/WebApp, because of needed plugins within Outlook. :(

Apache’s timeout and mySQL have been optimized on the server already. The storage of kopano is hosted on SSDs.
Any optimization hints or other help to identify and solve the stucking and hanging Outlook would be fine.

Thank you in advanced,
Christian.

Hi Christian

I also migrated some customers from SBS to Kopano with outlook and KOE - some have big Mailboxes too - I think one problem may be the workstation as Outlook with active Sync stores all emails local - so i have ssd’s on all workstations that works for me.
I also have implemented mailstore archiving so i can offload old mails from the mailbox and the user is able to access them through outlook (with plugin) deskapp/wepbapp (through intranet plugin) and mobile too

they are all working with this configs since 2,5 years and never had bad experience with it (SQL and Apache not optimized - still default configs with univention ucs)

only thing is the amount of folders in the mailbox - had problems with 2 accounts with about 1.900 folders in their mailbox - but that is a limitaion of outlook with active sync - we had to reduce the folders - now these accounts have about 1.650 folders and that works - but with huge folder count the initial sync takes long to start as z-push prepares the folders bevor starting to sync

As already mentioned in another post we are currently looking into implementing some limitations on opened shared folders and total mailbox sizes within KOE 2.0 to make the user experience a bit more smooth. From what we could see Outlook really seems to suffer with large sets of folders (~200) and large mailboxes (lets say above 10GB).

Such a notice has been added to https://kb.kopano.io/display/WIKI/Setting+up+the+Kopano+OL+Extension already a while back.

Hello,

I migrated +200 zarafa accounts to kopano. And the result is Outlook is not compatible.

I have listed this bug:
-KOE miss randomly on Outlook
-The mail is duplicated when I move my email to a folder
-Sync does not work or stuck in the refresh
-Ativesync Integration with software like “Sage” does not work
-Outlook Freezing

the problem appear on all Outlook 2013/2016, I have try latest office update etc

At this point, my customer need a new mailing software…
I have try Bluemind and Kerio and this software work great with Outlook

Best regards

@ivamp tyvm.
I can copy the same problems, unfortunatelly.

Wbrgds, Christian.

@onex-de, I’ve the same problem like @ivamp.
Sellers who have seen themselves selling dreams but when we ask a question to the technical support, there is nobody more. I think more and more that’s bullshit.
@ivamp thank you for your solutions, Bluemind it’s better.

@ivamp @onex-de @thehunterst does it change for you, if you limit the amount of days synced to outlook? how many folders do you synchronise?

To better understand your problems could you send the support case numbers to feedback at kopano dot io ?

Hi
I have open this ticket to your support
KS-39749
KS-40430
KS-39607

I think the best way are developping Imap Connector for Calendar and Contacts or Mapi plugin like Zarafa.
In other mailing software they work like this

Best regards

@fbartels
I cannot limit the amount of days, because our customer wants to have all mails available in his outlook, not an option.
Mayboxes have about 10-20 subfolders, are between 7-12 GB in size and have about 30k-60k mails in them.

Support case is KS-40480. (will sent via email, too)

Then you’re out of luck. If Outlook is not able to handle all items, then reducing the amount of items it the only feasible solution (apart from using WebApp/DeskApp of course).

@fbartels, and a DeskApp offline it is possible yet ?

no, and likely never will. At least not with the current WebApp as its backend.

I think, ActiveSync/Z-Push addresses this issue.
Outlook 2016 works fine with this mass of items connected to an MS Exchange Server.
But if one wants to migrate from MS Exchange to Kopano without loosing a lot of comfort and usability, this combination of Outlook 2013+ and Kopano doesn’t work as good as Outlook 2010 with zarafa-connector worked, unfortunatelly.

Sadly but true, I need to remigrate to Exchange again :-(

@ivamp & @thehunterst : Outlook and IMAP is no option at all.
Shared and public folders don’t work and calendar / contacts needs additional plugins as well.
As of mails is the only issue with Kopano and Outlook via z-push, I don’t see your other mentioned products as an alternative.

Christian.

@onex-de yes imap it’s not a perfect protocol, but if you can try Bluemind (for example) you have to configure account with Imap and install 1 additional plugins for shared calendar/contacts and public folder.

And Sincerely it’s work better ActiveSync

@ivamp said in Outlook suiteable as a kopano fat client?:

and install 1 additional plugins for shared calendar/contacts and public folder.

What about shared mailboxes, aka email folders?

It’s simply IMAP subscription

Outlook with ActiveSync (or actually ActiveSync itself) was never meant to handle GBs of data. It’s rather an exception to have GBs of data for an ActiveSync account on a mobile and even if one does, it’ll slow the mobile considerably.

You have to be aware that Outlook connected to an Exchange server or Exchange-like service via a connector behaves completely differently than Outlook over ActiveSync. Every groupware vendor runs in same issues when using Outlook over ActiveSync. Kopano with KOE solves some of the issues but don’t expect it to work it the same way as Outlook and MS Exchange or zarafa-connector.

So that brings the question of why Kopano can’t write (well, again) a native connector to Outlook? (by the way I am very happy with the present solution in my case).

@mcostan said in Outlook suiteable as a kopano fat client?:

why Kopano can’t write (well, again) a native connector to Outlook

It’s not that we can’t. But (and that was widely communicated when the old mapi client was discontinued) we don’t see a future in the Outlook desktop application, and therefore want to spent our available resources in areas we can innovate.

The Kopano Ol Extension provided a good way in the middle. Take whats already in Outlook and with manageable resources add some bits that we saw as essential.

@manfred thank you for the clearification.
Sad, that this circumstance was never published this way, officially.

In other words: Outlook 2013+ with a huge users mailbox doesn’t work.
If a user wants to have access to his mailbox, he doesn’t want to use different clients, one to work with and a partial mailbox, because he needs additional plugins and one to have access to all items.

Am I right, that searching and accessing mails older than one month isn’t possible when ActiveSync is set to sync one month or is there any way to access them within Outlook, except setting the sync to all?

Christian.
