Description

Users may find that Bracket notifications end up in their Junk Email folder, mainly if they are using Office 365 mailboxes. Despite Bracket having SPF, DKIM, and a simple content structure, Office 365 still filters the notifications and places them in the Junk Email folder of Outlook.

Unfortunately, Mailprotector cannot influence Office 365's email filters. Similar to the request seen in other emails from organizations recommending that you allow or whitelist an address or domain to receive their messages consistently, this article will describe how to create the allow rules in Office 365.

NOTE: In addition to these steps that can be performed for your client, there is an end-user focused article describing how to submit the Bracket messages to Microsoft as false positives to help with more consistent delivery in the future. Please see Notify Microsoft of False Positives of Bracket Notifications for details.

Adding Allow Rule in the Outlook Client

NOTE: If users do not have an Office 365 mailbox, then the Junk Email filter built into the Outlook client may be performing the action of putting Bracket notifications into the Junk Email folder. Typically, we recommend turning off the Junk Email function in the Outlook client to avoid such confusion since Mailprotector is already filtering email.

You have two options, the first is to turn off the Junk Email protection and the second is to add the bracket.email domain to the Safe Senders list.

1. From the Outlook client, click on the Junk menu button in the Outlook ribbon as shown in Figure 1.

2. The Junk Email Options dialog will open. The first tab will be 'Options,' and the setting may be on 'Low' or 'High.' Select 'No Automatic Filtering' to disable the Junk Email function. Only senders listed on the 'Blocked Senders' tab will still go to the Junk Email folder.
   
   
3. To add an allow rule for Bracket, select the 'Safe Senders' tab in the dialog box. Click on the Add.. button and enter @bracket.email as shown in Figure 2. Click the OK button to add the domain to the list.

4. Finally, click the Apply then OK buttons to complete the process.

Office 365's Exchange Admin Center

Adding Allowed Senders

1. Login to the tenant domain and navigate to the Exchange Admin Center. From the Exchange Admin Center dashboard, click on spam filter under the protection group of links. This will take you to the spam filter rules page as shown in Figure 3.

2. A 'Default' rule will exist, but you may have others depending on the client's situation. This article will work with the Default rule; you may need to choose another enabled rule.
   
   With the 'Default' rule highlighted, click on the pencil icon to edit the 'Default' rule. The 'edit spam filter policy' dialog window will open. Click on allow lists to display the list options as shown in Figure 4.

3. The top list is for sender addresses. Click the '+' icon under the Sender allow list. You will be adding two addresses to this list, separated by a semi-colon:
   signin@bracket.email;do.not.reply.with.email@bracket.email
   
   The two addresses will be listed in the Sender allow list as shown in Figure 5. Click the Save button to complete the steps.

Adding Allowed Domains

Adding an allowed domain will be easier and more efficient. However, some client policies may dictate that security exceptions be implemented in the most granular way possible. In those situations, the above steps for adding allowed senders is preferable.

1. To add an allowed domain, follow the first two steps from above and be sure you are viewing the 'edit spam filter policy' dialog window as shown in Figure 4.
   
   
2. The bottom list is for allowed domains. Click the '+' icon under the Domain allow list. You will be adding a single domain to this list:
   bracket.email
   
   The domain will be listed in the Domain allow list as shown in Figure 6. Click the Save button to complete the steps.

Adding either the allowed senders or domain to the Office 365 spam filter policy should prevent the Bracket notifications from going to the users' Junk Email folder. If you have additional questions, please submit a request to support.
