[img]./fa/3369/0/[/img]Hello,

i have a problem with the size of Kerio Outlook Connector Offline cache.
The size of the cache files is much more than the users e-mail size on the server.
Users e-mail on server: 2.1 GB
Kerio Connector Offline cache: ~60 GB
The size of the cach files is growing till the HD is full! About 40GB per month.

I have this problem with 2 users. I already cleared the cache and do a resync.
I already did a new install of the Kerio Outlook Offline Connector but that didn't
solve the problem, after a few weeks the harddisk is full again. The other 140 clients
works fine.


Kerio Connect 8.2.1
Server: CentOS 5.x
Client: Windows 7 64bit, MS Outlook 2007

Hi Christian,

Please try the following:

(1) Stop Kerio Connect service on the server, close your Outlook on the workstation.

(2) Locate user's folder in the store (for example C:\Program Files\Kerio\Connect\store\mail\DOMAIN.COM\USER\).

(3) Rename '__keriomapi__STORE' to '__keriomapi__STORE_old'

(5) Start the Kerio Connect service.

(6) On the workstation, go to Control Panel in your OS - Mail (32-bit) - E-mail Accounts... - Change... - Maintenance and press the [Empty] button.

(7) Start your Outlook and let it sync from the scratch.


Let me know if it helps.

Hi Jonas,

thank you for the quick response.
Yesterday i have done the steps that you told me for the server and client.
I'll watch the size of the cache files in the next few days and report the result here.

Hi Jonas,

so after a few days i must say that the problem is not solved.
After 5 days the file size has grown up to 26GB again (Screenshot).
What else can i do to solve this problem?

Christian

What version of Kerio Connect and the KOFF are you running? Are there large attachments to the emails?

I believe starting with v8, KOFF doesn't download attachments in to the cache that are over 6 months old, or something like that to help control the size of the local cache files. My 12GB mail store on the server is less than 4GB in the local cache. Running Connect v8.1.2.

Hi

Try to use dbbackup utility installed with KOFF. It allows shrinking KOFF databases by removing most of the unused space. Run it from the command line by the command "dbbackup s <profile name>".
It can take some time (tens of minutes with large mailboxes) and KOFF mustn't be used during the operation, so I recommend to run in the evening when the user goes home.

Please write back if the utility was able to shrink the database to the reasonable size.

only an idea: use the user shared folders from other users? Could this be the source of the big local cache files?

Hi,

sorry for my late answer, but the user who had that
problem was not in the office for the last two weeks.

He reported to me yesterday that since the update to
kerio connect 8.2.3 (and deleting the offline cache)
the problem is solved.

Now he has 2 files with in summary 400 MByte space and
not growing.

So for now the problem is solved for me. I'll report here
if the status should change.

Thanks

Is anyone else having this issue? Kerio 8.3.2 and I'm getting massive fdb files even though the users mailbox is small.

I've rebuild the file in the past but that doesn't really solve the problem as it keeps growing. e.g 60gb for a 9gb mailbox!

Sorry, I need to ask before trying to find the reason why is your local storage so huge. Are you sure that it is your mailbox that takes those 60gb? There is separate fdb file for every mailbox you are connecting to. There is one file for public folders and there is one file for every attached shared mailbox. Maybe some of other mailboxes is really so huge.

If you can confirm that the size of your local storage is not caused by attaching to some huge mailbox (or huge public folders), can you try dbbackup utility to shrink the database (I described the usage in some post in this forum thread)? What is the size of the fdb file after the shrinking?

Hello everybody,

i tried to to perform this job for each of our AD-Users by logoff from the pc.
Without success. Crying or Very Sad
A batch-script start the job and open this one in a new window.
So user must press an a button to finish the logoff-Procedure. Thats sad.

So i created a Powershell-Script (.ps1) with following lines:

$p = [Diagnostics.Process]::Start("DBBackup.exe", "s profile-name")
$p.WaitForExit()


You can take the GPO-Logoff-Script and to use this ps1 at option "PowerShell-Scripts".
So it will perform this job without any user interaction at this Logoff-Procedure.

I hope this will help another admins!

Best wishes!
