    I did find a solution/workaround (below) for the error message "The rules on this computer do not match the rules on Microsoft Exchange" followed by the inability to see or edit rules in either Outlook for the web or Outlook Classic on the desktop.

    This has been an issue for Outlook since late 2019 without any actual answers. All other related tickets have had responses disabled even though they offer no solutions or really even any theories.

    Solution/Workaround:
    I was able to access my rules, edit the rules, and identify and delete the offending rules by switching over to New Outlook using the toggle at the top right of the page - then, using the same toggle, I was able to switch back to "Outlook Classic" (real Outlook), because New Outlook is still garbage.

    When in "New Outlook", just go into the Rules as you would normally and the whole list will be there. There will likely be a rule or two that will indicate that it cannot be read by Outlook for the desktop. If you are able to see those in the web interface, they will tell you they can't be read by Outlook for the Web. These are your offending rules. You'll likely also see some that are greyed out - those are just disabled and you'll still be able to edit or enable them. There is a switch at the top of the New Outlook Rules screen that will show the description for all the rules so you can see what each rule is configured to do. I found this helpful as opposed to clicking on each rule individually.

    That is the actual problem here. going here (In Outlook, click on File and then Manage Rules & Alerts. or from home ->move-> manage rules) will block and throw an error. I will keep you posted on it . what helped resolving the issue @Demi-N

    Hello mary rebecca,

    Thanks for reaching out about the issues you're experiencing with Outlook. 

    The errors you're encountering often point to synchronization issues or local profile corruption: 

    • "The delegate page is not available. Cannot access Outlook folder." This usually means Outlook can't connect properly to set up delegate permissions, possibly due to a connection issue or a damaged Outlook profile. 
    • "The rules on this computer do not match the rules on Microsoft Exchange..." This occurs when your local email rules aren't synced with those on the Exchange server. You'll want to keep the rules on the server when prompted, as they're typically the most up-to-date. 

     

    Given these symptoms, here are some steps you might try to troubleshoot and resolve these issues: 

    1. Choose Server Rules for Synchronization: For the "Manage Rules" error, when you see that prompt, always choose to keep the rules on the server. This will synchronize your local rules with the server's version, which is generally the most reliable and up-to-date set. This step often resolves rule-related conflicts and can sometimes even positively impact other synchronization issues. 

    2. Check Your Outlook Connectivity: Ensure Outlook is fully connected to the Exchange server. Look at the bottom right corner of your Outlook window; it should say "Connected to Microsoft Exchange" or "Online." If it's showing "Disconnected," "Needs Password," or "Working Offline," try restarting Outlook or checking your network connection. 

    You can find troubleshooting steps for Outlook connection issues here: Fix Outlook connection problems in Microsoft 365 - Exchange | Microsoft Learn 

    3. Create a New Outlook Profile: A corrupted Outlook profile is a frequent cause for both these types of errors. Creating a fresh profile can often clear up underlying data issues without affecting your actual mailbox data on the server. 

    Here's how to create a new Outlook profile: Create an Outlook profile 

    4. Repair Office Installation: Sometimes, the Office installation itself can have minor corruptions. 

    • Right-click the Start button, and select Apps and Features on the pop-menu. 
    • Select the Microsoft Office product you want to repair, and select Modify
    • Choose one of these options based on what's presented: 
    • In the window How would you like to repair your Office Programs, select Online Repair > Repair to make sure everything gets fixed. (The faster Quick Repair option is also available, but it only detects and then replaces corrupted files.) 
    • In Change your installation, select Repair and then select Continue

    You can find instructions for repairing an Office application here: Repair an Office application - Microsoft Support 

    5. Ensure Outlook and Windows are Updated: Make sure your Outlook client and Windows operating system are fully updated with the latest patches. Updates often contain fixes for known bugs and compatibility issues. 

    I hope this information helps you get things back on track. Please let me know how these steps work out for you, and we'll continue troubleshooting if needed!
