Event id 9667. How can I increase quota limit for named properties?

Posted on 2011-03-08
Last Modified: 2012-05-11
I've reached the "number of named properties" quota limit on one of my mailstores, so I am getting multiple 9667 events in the apps log. The limit is set at 8192. How high can this limit go? Can I double it to 16384? What are the consequences?

Thank you

The correct way to resolve this is to create another mailstore and move some users.

This should give you some insight to the effects of the change.  You shouldn't have any issues doubling the current size.

I was hoping that by service apck 3 MS would have come up with a permanaet fix for this that doesn't involve moving mailbxoes. Anyway, I read, apparently we;ve had this problem before because may of stores have a registery entry of NonMAPI Named Props Quota set to 8192. The article says to create both. I'm a bit confused.

Someone must have added the values at some point in the past; there shouldn't be any issues with raising the values to 16K.

What's the difference between "NonMAPI Named Props Quota"  and "Named Props Quota " and which one is the error refering too?

"If you are receiving the error Event 9667 or 9669, it is likely that your users are already receiving errors and you should implement an EMERGENCY maintenance operation to increase the configured quotas."

"After you recover from the depletion of named properties or replica identifiers, you should attempt to discover the reason why an increased number of named properties or replica identifiers are used."

From the first link I have posted. There are also further recommendations.

(Sorry, copy-paste -  I'm so lazy ;))

1. Change the Registry value of Named Props Quota to 16384 by going to following location in registry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\Private-00000000-0000-0000-0000-00000000

2. Increase the Registry value of NonMAPI Named Props Quota to 16384

3. Dismounted and remount the store
