Exchange 2010 rulesquota size limit and how to increase it

Posted on  by Morten Nielsen  No Comments ↓

Was cleaning up my inbox and creating some new rules, when I recieved this message:

“One or more rules could not be uploaded to Exchange server and have been deactivated. This could be because some of the parameters are not supported or there is insufficient space to store all of your rules.”

The Danish image is from my PC. The English one is found using Google:

 

Found that it was due to a rules size limit. Or to be specific a rulesquota setting, which defaults to 64KB.

If you just want to remove all your rules instead, you can run Outlook by typing (client side):

Outlook /CleanRules

Exchange 2010 rulesquota size limit and how to increase it.

By default Exchange 2007 / 2010 rule size is 64 KB but is expandable to 256 KB.

Lets first check if the size is set to 64KB:

Get-Mailbox [email protected] | fl rulesquota
RulesQuota : 64 KB (65,536 bytes)

It was indeed 64KB. Now lets increase it to 256KB:

Set-Mailbox [email protected] -rulesquota 256KB

Did it Work:

Get-Mailbox [email protected] | fl rulesquota
RulesQuota : 256 KB (262,144 bytes)

Now, lets set it or all users.

get-mailbox|set-mailbox -rulesquota 256kb

And check the setting.

get-mailbox|ft rulesquota, alias
