Outlook Rules Quota

Hi All,

Recently i had the following Error Message in Outlook:

Mindestens eine Regel kann nicht in Microsoft Exchange hochgeladen werden und wurde deaktiviert. Die Ursache sind möglicherweise nicht unterstützte Parameter oder mangelnder Speicherplatz.

One or more rules couldn't be uploaded to Exchange server and have been deactivated. This could be because some of the parameters aren't supported or there's insufficient space to store all your rules.

Let's have a look at the Mailbox and the Rules Quota - it's already set to the Maximum of 256 KB.

Get-Mailbox -Identity a.bohren@icewolf.ch | fl RulesQuota

To set the Rules Quota, you can use this command

Set-Mailbox a.bohren@icewolf.ch -RulesQuota:256kb

Microsoft explains on the following website, what you can do

Some rules are disabled, and you receive an error message when you try to create or enable rules in Outlook

Method 1 - Rename your rules to a shorter name
Method 2 - Delete any old rules
Method 3 - Combine similar rules to reduce the overall size of your rules
Method 4 - Move your personal folders (.pst) file to a location that has the shortest path name
Method 5 - Clear the on this machine only check box.

I ended up, deleting some old Rules and that fixes it for me.
