Edit client side rule on shared mailbox in Exchange Online

We have an O365 shared mailbox that was converted from an on premise mailbox when migrating to Exchange Online. Now I've been asked to update the auto response rule but am running into a problem. Because this is a shared mailbox we can't log into it directly so the only way to change the rules is by opening another mailbox in OWA. Unfortunately the rule is client side only and shows the following message: This rule can't be edited or viewed in Outlook on the web Is there a recommended way to deal with this problem? I have two potential solutions in mind but neither is ideal so I'm hoping for a third option.

  1. Delete the rule and recreate it in OWA. This is not preferred because I want to confirm the settings of the rule before making any changes.
  2. License the mailbox, convert to a user mailbox, reset the password and log in directly using the outlook app so that changes can be made before converting back to a shared mailbox and removing the license again. There has to be a better method than this, I'd rather not mess with a mailbox that is the primary method for customers to contact us.

Hopefully someone has a better approach.
Thanks

    Hello,

    Welcome to our forum!

    Considering your concerns, here are some other methods for your reference:

    1. By manually adding a shared mailbox account to Outlook, please follow these steps: Open the Outlook client, select File --> Add Account, on the "Automatic Account Setup" screen. Enter the email address of the shared mailbox, for the password, please enter the password for your own email account. Then select Next to proceed. Change the email address to sign in with by selecting Sign in with another account. Sign in with your own account credentials and select Finish. You will need to restart Outlook for the changes to take effect. After restart Oulook. Click Rules --> Manage Rules and Alerts to edit.
    2. Run the following cmdlet in Exchange Online PowerShell: Set-MailboxAutoReplyConfiguration
    3. Try to sign in to the Microsoft 365 portal, then locate Groups > Shared Mailboxes, select a user who has a Microsoft Exchange mailbox, and find Automatic replies on the flyout on the right.
