Improve - speed up Outlook connector KOFF
This is still being worked on
When you originally released 9.2.6, it had a fix for KOFF to make it faster, but was quickly pulled back when it was determined it was not working properly. So is this still being worked on, or has the idea been shelved? We have been dealing with slow KOFF performance issues for years and was really looking forward to the issue being addressed.

Agreed with Karolini. Drop KOFF and implement a native Exchange connection for the Kerio accounts from Outlook.

This is a waste of time to speed up KOFF. This thread is 7 years old and KOFF is still slow compared to Exchange / Activesync (with same mailbox data) - why not just implement Native Exchange compatibility in Kerio Mail Server and be done with it. We actually plan to migrate to another mail server with native Exchange compatibility because of Kerios / GFIs ignorance on KOFF matter.

we are already using SSD,
but with big mailboxes it is too slow,
when searching for mails you can go for a coffee.
this should be TOP-PRIORITY!

We are currently looking at ways to provide performance improvements that should benefit all Kerio Connect users.

In my opinion the only way is to switch to a SSD. Compare KOFF Firebird database of let's say 10-20 GB size with a PST/OST of the same size and you end up needing SSD anyway. During the last years the SSD size grew and prices dropped significantly, so for a heavy worker that is the way to go now.

What's the status on this 3-year project?

This project was started on Feb 1, 2012... How it is now?

I can support this. KOFF is REALLY slow with bigger mailboxes, especially for roadworkers with laptops and 5.4k drives. Not everyone runs SSD's.
Please investigate in the OutlookOfflineConnector. Ist sooooooo slow. Espeacialy Changing beween clander and mail view, or searches in emailfolder with a few thousand mails. Exchange PST or OST are much faster. If KOFF Needs more RAM to be fast, OK! Most PC have plenty of RAM.
I really push my customers to choose Kerio vs. Exchange, but now I'm in serious troubles because ALL of my customers are complaining about Outlook (with KOFF) being TOO MUCH SLOW.
The only improvement that has happened here is relying on customers to purchase fast SSDs... I see no improvement to this issue for 3 years

Searchspeed and Startup in Outlook with KOFF is a drama.

Any comments on this ?

How is the performance improvement going? Because the last update dates back 2+ years...
Synchronization has gotten faster but search speed is awful (8.3.2).
C. Spann commented
20 users consuming about 120 GB on Windows Terminal Servers just for caching mails that already are online on kerio server! Please STOP that.!
... also the receiving of messages after 2 weeks of holiday, takes a while and there is no window, no sign, no send/revice-status in outlook.
For users: it looks like, it doesn't work

Please keep this up! We like Kerio but it's too slow on outlook - WAY too slow (we are on 7.4.2). we have many users with >1G, probably 25+ (all the senior management) with 10G+.

@administrador: That's not true. It is not the account size but sometimes the folder size that matters.
i don't understand why PST is so much faster while KOFF is using a database. Maybe there is a way to build KOFF so it uses pst as a storage?
