A user had mismatched rules in Outlook and his Exchange mailbox and wasn't sure what to do.
When I edit my rules, Outlook always asked if I want to use the Client or Server rules. What is the difference between them? Which should I be using?
Outlook stores rules in the Exchange server mailbox (including Outlook.com accounts) and syncs a copy of the rules to Outlook on your desktop. This message comes up when Outlook detects the rules on the server are not identical to the rules stored in the Outlook data file and Outlook needs to know which ones you want to work with. If you know one set is correct, choose it, otherwise choose Server.
To eliminate the message, you can start Outlook with one of the cleanrules switches:
| Switch | Description |
|---|---|
| /cleanrules | Removes rules from both Outlook data file and the server mailbox |
| /cleanclientrules | Only removes the client side rules |
| /cleanserverrules | Only removes the server side rules |
If you clear only the client rules, the server rules will sync down to Outlook; clearing the server rules works the same way, with the rules stored in Outlook syncing up to the server.
You'll first want to export the rules. This will allow you to restore the rules quickly and provides insurance, should something go wrong and you decide to delete all of the rules.
- Open the Rules & Alerts dialog, click Options and then Export rules.
- Close the Rules & Alerts dialog then close Outlook.
- Press Windows key + R on your keyboard to open the Run command.
- Type or paste outlook.exe /cleanrules in the Open field to clear all rules.
Use outlook.exe /cleanserverrules if you know some client rules didn't sync up to the server.
Use outlook.exe /cleanclientrules to keep the server rules.
- Press Ok to restart Outlook.
If you used the /cleanrules switch, import the rules you backed up earlier. If you used either the client or server switch, open the Rules & Alerts dialog and choose which rules to keep one last time. The rules will sync so both client and server are identical.
I got the error message and clicked "Client" because I had been setting up rules all morning and figured they hadn't synced to the server yet. Apparently, that wasn't the right choice. I lost most of my many rules and the ones that are here I do not recognize. How do I revert this?
How do you know what rules are on what list? I cant even access my rules from the "Manage Rules and Alerts" tab, because it then asks, that dialog, "which do you want to keep" How am I supposed to know if it doesn't allow me to see which ones are where?
Log into OWA and check the rules - those are server rules. The rules you see in outlook are probably the client rules, but there is no way to know for sure. If the rules in OWA look complete, choose the server rules and stick with them.
This was exactly what I needed! Thank you!
