Run Rule Now Option Greyed Out for Certain Rules

Chidimma-8931 0

I work at the university I attend, and as such, I now have a work email in addition to my regular school email (both outlook). In the school's admin system, the work email becomes the dominant email, and so all my school notifications are now sent to my work email. I have been trying to set up rules in the work email to "redirect" these emails to my school email, but all of the rules I've made that are related to that haven't been working. The option to Run Rule Now is greyed out, and it doesn't seem to take effect for the future emails that have arrived in my inbox. Is there something I'm missing? I successfully did this last year, so I'm not entirely sure what, exactly, is the issue now.

What is meant by "sever-side" or "client-side"?? And what sort of rule does this excerpt reference: "is a simple new Outlook rule with only supported conditions/actions. Avoid anything that depends on on this machine only behavior or local folders." ???

Dear @Chidimma-8931

I understand that you want to automatically redirect school-related messages from your work mailbox to your school mailbox, but the rules you created are not taking effect and Run Rule Now is greyed out.

To narrow down whether this is related to the Outlook version or the rule configuration, could you please confirm the following?

Which Outlook are you using?
- New Outlook app for Windows
- Outlook on the web
Where did you create the rule? Please provide the exact path, for example Settings > Mail > Rules or File > Manage Rules & Alerts.
Could you provide a screenshot of one affected rule, showing its conditions and actions? Please hide any email addresses or other personal information.
Does the rule work automatically for new incoming messages, or does it fail completely?
Are the work and school accounts both Microsoft 365/Exchange accounts, or is either account a personal Outlook.com account?

Please try these simple steps:

Create a new rule in Outlook.
Use a simple condition, such as From or Subject contains.
For the action, select Redirect to and enter your school email address.
Do not select options such as “on this computer only” or actions involving local folders.
Save the rule and send yourself a new test email that meets the condition.

If the new test email is still not redirected, please let me know which Outlook version you are using (New Outlook or Outlook on the web) and provide a screenshot of the rule.

The Run Rule Now option is particularly useful for identifying the Outlook version involved, because its availability and behavior differ between Classic Outlook and the newer Outlook experiences.

Once I know these details, I can determine whether the issue is with the rule itself, the Outlook client, or an account/organization restriction.

I am using Outlook on the Web mostly, but I tried briefly with the new Outlook app.

File > Settings > Email > Rules

RED is just different professor names --- I want whatever emails they send me to be rerouted

and yellow is the school email I am redirecting to

It seems to fail completely. It doesn't seem to be working for old or new messages

They're both school/work accounts

I'll try your suggestion, but I do also have this rule that never had a folder in it that also wasn't working tho

And how do I send myself a test email if I don't have access to the email accounts of the people named in the conditions? I have other rules that work fine, it's just these school ones that are giving me issues

Dear @Chidimma-8931

Thank you for the additional details and for providing the screenshot. That clarifies the situation.

Since you are primarily using Outlook on the web, both accounts are school/work Microsoft 365 accounts, and your other rules are working normally, this does not appear to be a general Outlook Rules issue.

For the rules that redirect messages from your professors, I would first check whether the sender condition is matching the actual sender address. The display name shown in Outlook may not always be sufficient for a rule condition.

You do not need access to your professors’ accounts to perform a test. You can use an existing message from one of the affected professors:

Open one of the messages from a professor that should have been redirected.

Check the actual sender email address.

Edit the affected rule under Settings > Mail > Rules and verify that the condition is based on the correct sender/address.

Save the rule and then wait for a new message from that sender to arrive. Since the rule is intended for incoming mail, a new matching message is a better test than relying on Run Rule Now.

If possible, temporarily create a simple test rule using a condition you can reproduce yourself, such as a unique word in the subject, with the action Redirect to your school email address. This will help us determine whether the problem is specifically related to the sender condition or to the redirect action.

Regarding Run Rule Now, its availability and behavior differ between Outlook on the web, New Outlook, and Classic Outlook. In New Outlook, rules are server-side, and not every rule/action supports the same manual execution behavior as Classic Outlook.

Because you mentioned that you also have another rule that does not work even though it does not involve a folder, I would particularly like to determine whether Redirect to itself is failing or whether only the professor/sender conditions are failing.

If you can share the exact conditions and actions of that second non-working rule (with email addresses/personal information hidden), I can help you compare the two rules and identify what they have in common.

Answer 2

In new Outlook, this usually happens because the rule is not a fully supported server-side rule.

A common cause is that the rule was migrated from classic Outlook as a client-side rule. New Outlook does not support client-side rules. When that happens, the rule may show This rule can't be edited or viewed, and it will not behave normally in new Outlook.

For a forwarding/redirect scenario, check these points:

Open Settings in new Outlook.
Go to Mail > Rules.
Review the rule that is supposed to send the messages to the school mailbox.
If the rule cannot be edited or viewed, recreate it in new Outlook instead of using the old one.
If it can be edited, select Edit, confirm the conditions and action, then select Save.

Also note:

If the rule uses conditions or actions that existed in classic Outlook but are not supported in new Outlook, it will not work the same way.
New Outlook does not have the same classic Run Rules Now behavior for all rules. Based on the available guidance, rules in new Outlook can be run individually from Settings > Mail > Rules rather than using the classic bulk/manual run experience.
Rules that depend on local or client-only behavior are the ones most likely to fail or have limited options in new Outlook.

If this worked last year, the likely difference is that the earlier rule was created or running in classic Outlook, while the current mailbox experience is now in new Outlook where client-side rules are not supported.

If the rule is intended only to forward incoming mail, recreate it as a simple new Outlook rule with only supported conditions/actions. Avoid anything that depends on on this machine only behavior or local folders.
