What is the maximum folder size that I should allow on our mail server? Right now we have users that have folders big as 1.8 GB. If this is too big, and we need to create subfolders, what would be the optimal size of every subfolder?

Thank you in advance on your time and reply.

Best regards.

Hello Tomislav,

Big is never good in terms of mailbox sizes! But we are more concerned that you do not exceed 10,000 items per folder - that will affect performance.

That goes for folders and subfolders.

I hope this helps.

Best regards,

Neil.

Hi Neil,

thank you for your reply.

I know that big is no good, but what is big for today computers? Where should I draw the line?

Those 10,000 items, what exactly does this mean?
- Inbox folder, with all it's subfolders shouldn't contain more than 10,000 items or,
- every (sub)folder on it's own shouldn't contain more than 10,000 items?

Thank you in advance on your reply.

Best regards and have a nice day.

Hi Tomislav,

We recommend no more than 10,000 items per folder. So this would only be subject to the actual folder not the folder and all of its sub folders combind.

The 10,000 limit is for each folder the user has in their mailbox so every root folder or sub folder should not have more than 10,000 items really.

I hope this helps and makes things a little clearer.

All the best,
Vicky

Hi Vicky,

thank you for your reply.

Yes, you have made things clearer.

Can you please comment the size of directory in therm of amount of data. How much data is too much? I mean, if I have directory with less than 5,000 items, how much data will be acceptable? 1 GB, 5 GB, 10 GB, 20 GB, 50 GB or more? Where should i draw the line, or I don't need to worry about the size of directory if it has less than 10,000 items?

Thank you in advance on your reply.

Best regards.

Hi Tomislav,

In regards to size in MB/GB we do not really have a guide. I personally would say anything above 20GB would be worth going through and cleaning up as in my opinion is towards the larger size of a mailbox.

But generally it really does come down to the item count as our file structure is a flat file structure and not a database, so if Kerio needs to re-index a folder the lower the item count the quicker it can re-index.

I hope this helps,
Vicky

Sorry to glob on to another (and few month old) post. I just want to make sure I read this right.

The per-user quota setting allows me to set it by size and/or quantity. This thread leads me to believe this is PER FOLDER, not a total for the account. Is this the case?

I have been using quotas for years (currently on 7.4.3) and have always thought the limit was on the user's mailbox, which includes inbox, subfolders, sent items, etc.

Can someone verify exactly what rules the quota rules enforce? Per account or per folder? If it's per folder, then all a user has to do is, theoretically, make a bunch of subfolders and end up with a 200GB mailbox!

Thanks,

Jeff

Hi Jeff,

When you set a user quota in the Kerio Connect We Admin the quota is for the entire account of the user. So Kerio will calculate the size of each folder and use the total size of the Mailbox to enforce the quota limit.

The only folder that is the exception is the '#Deleted' folder which is the deleted items retention folder (which is a feature you have to enable within the Web Admin).

All the best,
Vicky
