One or more rules could not be uploaded to Exchange server and have been deactivated

Few days ago we  had an issue on an Outlook 2013 client on Exchange 2010 ,  when the user want to create a rule he received the following alert.

“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 your rules.”

To solve this problem we just  need to deleted some rule or increase  rule limit size. The default  rule limit size is 64kb.

To increase  rule limit size type the following command on powershell:

Get-Mailbox tekbloq.user | Set-Mailbox -RulesQuota 256KB

2outlookrulelimit

In this command we increased limit size to 256KB.

After this changes  they were able to create additional rules.
