Setting up forwarding rules in Office 365

Author: Anand Raju

A key part of setting up your own custom support emails with Desk365 is making sure you’ve set up the correct forwarding rules so that emails sent to your custom email are forwarded to Desk365.

In this help center article, we’ll go over how to do this in Office365.

Forwarding email address

The first step is to identify the Desk365 provided email address to which you’ll need to forward your emails. For example, in the setup shown in the image below, the custom support email is support@kanidesk.com and the email to which you need to forward is: support@devtest.desk365.io.

Set up forwarding in the Microsoft365 admin center

The recommended way to set up forwarding is from the Microsoft365 Admin Center. These are the steps you need to take to set up forwarding on your Office 365 account:

1. Login to your Office 365 portal using your administrator account. From the menu on top, click Admin > Exchange to open Exchange Admin Center.

2. From the menu on the left, click Mail Flow to create the forwarding rule.

3. In the Rules tab, click the ‘+’ (plus) button and select Create a new rule.

4. Enter a name for this rule. We’ve given Rule Name as ‘Desk365 forwarding rule’ for this example.

5. Under “Apply this rule if…” option,  choose: The recipient is.

6. From the next page, select your company’s support email address (support@kanidesk.com) and click OK.

5. Click Save.

Now that you’re done with forwarding, you can refer to our previous article in which we’ve explained the steps needed to configure your custom support email in Desk365.

Common forwarding errors to look out for

1. Avoid setting up forwarding using the ”Rules” option under settings. This results in emails being forwarded with a “FW:” prefix and the Contact not getting set up properly within your helpdesk.

2. If you haven’t done already, we suggest enabling external email forwarding in Microsoft 365.

If a user has set up an automatic forwarding rule to an external address in their Microsoft 365 mailbox using Outlook, the message will not be forwarded when the rule is triggered. Instead, the user will receive a non-delivery report (NDR) indicating that the message was not delivered.

‘Remote Server returned ‘550 5.7.520 Access denied, Your organization does not allow external forwarding. Please contact your administrator for further assistance. AS(7555)’.

Even though a user sets up forwarding, a Global Admin has to first enable external forwarding. The outbound spam protection settings and automatic external forwarding can be enabled for any mailboxes by a Microsoft 365 administrator.

Here are the steps to do:

(i) Log in to the Microsoft 365 Defender Portal as a global admin.

(ii) Navigate to Policies & rules -> Threat policies.

(iii) Choose ‘Anti-spam policies’ option here.

(iv) Locate the ‘Anti-spam outbound policy’ in the list and select ‘Edit protection settings’.

(v) Look for the ‘Forwarding rules’ section and select the ‘On-Forwarding is enabled’ option from the dropdown menu under Automatic forwarding rules to allow email forwarding.

3. We also recommend you to set up DKIM records for your domain.
