I have a user that was on a 64KB rule limit, i have used the following command:
get-mailbox (user) | set-mailbox -rulesquota 256kb
to expand his rules, needless to say this does not work. I have restarted the information store and I also verified the limit was correctly set:
[PS] C:\Windows\system32>get-mailbox (user) | fl rulesquota
RulesQuota : 256 KB (262,144 bytes)
When trying to add a email address to an existing rule he has setup he recieves the error:
"One or more rules cannot be uploaded to Microsoft Exchange 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"
When I try to add an email address to an existing rule in OWA i get:
"Using Outlook Web App or Windows PowerShell to modify your rules will delete any rules that were previously turned off using Outlook. If you want to preserver the rules you turned off using Outlook, select "No" and use Outlook to edit your rules. Are you sure you want to proceed?"
We had no rules turned off of outlook so I just state no on this message. Not sure if it would delete one of my rules. I have created dummy rules under my own account and i can duplicate the messages this user gets as well.
We are running Exchange 2010 with all rollup 1, 2, 3 and 5 v2 installed.
