Part 3: Various Fixes To Resolve The Outlook Automatic Reply Not Working Issue

After understanding the causes of the problem, we can move towards effective solutions. Check the main fixes below:

Solution 1: Configure The OOF Feature

Follow the Steps below to configure the OOF feature:

Step1 Below, two cmdlets in Windows PowerShell are available. Use either of them:

Set-MailboxAutoReplyConfiguration <identity> -AutoReplyState Disabled

Set-MailboxAutoReplyConfiguration <identity> -AutoReplyState Enabled

Step2 Use MFCMapi to check the PR_00F_STATE value. Follow the below Steps to do this:

Solution 2: Delete and Re-enable The OOF Feature

The next solution to fix the Outlook Automatic Reply not working issue is by deleting and re-enabling the OOF feature.

DELETE: Steps To Delete The OOF Rules

Step1 Select Session in the MFCMapi main window. Open the mailbox by choosing the Logon and Display Store Table.

Step2 Now, expand the root container and information store top.

Step3 Delete the OOF rules. Delete by following the below Steps:

METHOD 1: Delete OOF Rules

StepA Right-click the Inbox and choose the Display Rules Table.

StepB If the OOF feature is not enabled, you can see the OOF rule listed in the rules table together. The following rule name can be seen:


StepC In case the OOF feature is enabled, you can see two different OOF rules listed in the table. The listed rule depends on if the rule is enabled only internally or both internally and externally.

Check the image below as an example:

two different listed oof rules

StepD If the OOF templates are corrupted, they will be listed on the rule table. Other entries can be seen if the user has enabled them.

StepE Right-click on the OOF rules and hit the Delete option. (NOTE: Except for referenced OOF rules, do not delete any other rules.)

StepF Close the windows of the Rules table.

Set-MailboxAutoReplyConfiguration \<identity> -AutoReplyState Disabled

Set-MailboxAutoReplyConfiguration \<identity> -AutoReplyState Enabled

Step2 Lastly, check if the OOF feature is working expectedly. Besides, the symptoms are no longer occurring.

Solution 3: Increase The Rules Quota

We have seen that extended rules quota can be the reason for the issue of Outlook Automatic Reply not working. It means both internal and external OOF rules can't be created.

The following Steps can help resolve the issue:

Step1 Determine the size limit for rules in the mailbox. Now, run the below command in the Exchange Management Shell:

check the size limit of rules

Step2 If the size limit is less than 256 kilobytes, run the following command. It will increase the size to 256 kilobytes:

follow the command to increase the size limit

Step3 Due to the caching of quota information in the Information store, up to two hours may be required to update the quota values.

Solution 4: Filter The Junk Emails Out Of Automatic Replies

All the suspected spam messages in Microsoft Outlook are stored in the Junk Email folder. It doesn't block messages. Moreover, the folder is saved on the Server and easily accessible from any system.

The Out of Office is also considered an automated message. The Junk Email filter's role is to filter it. It means the messages are present in the Junk Email Folder. Users can access the server's Junk folder and access email messages.

The image below shows the clear options to select and then select Reset:

choose desired options and click reset

Solution 5: Resolve Outlook Automatic Reply Not Working Outside The Organization

This solution prevents the auto-replies from going to email addresses that do not exist in the environment of organization exchange. The admin has to change the automatic replies settings for not sending replies outside the organization.

Furthermore, you need to automatically check the box to reply to people outside the organization. After changing the settings, Outlook Automatic reply will be capable of communicating with non-members of the organization.

Solution 6: Fix The Outlook Automatic Replies Once Per Address

By default, the assistant responds to each address only once. But sometimes, a user needs to resend the message to all the addresses. Next, the user has to turn OFF the OOF features and turn them on again.

Moreover, the rules of the server side enable the users to respond to all the messages they receive. Hence, end users should consider contacting the Exchange Administrator regarding this.

Solution 3 lets you increase the size limit for the OOF rules. The best time to use this solution is when you can notice the OOF rules are extending.

However, solution 4 is about filtering junk emails. In this solution, you check the Junk Email folder and modify a few settings. Leverage this solution when you are not able to see the emails in your inbox. They might be directed to the Junk Email folder. Furthermore, solution 5 is also effective and deals with the unwanted sending of emails outside the organization.
