UPDATED 25th Sept 2019
Updated due to changes in the Office 365 admin section

Microsoft implemented DKIM signing for outbound emails early in 2015 but the implementation was still a little clunky, requiring knowledge of the DKIM DNS formatting and the liberal application PowerShell commands.

Fortunately, they have improved this and placed it within the grasp of the average user and/or administrator. I’ve outlined the steps below to make this as easy as possible.

1. Enable DKIM on Office 365

Login to Office 365 using an account with administrative rights via http://portal.microsoftonline.com.

Click the menu button in the top left corner (it looks like a telephone dial pad)

Click Admin

Click … Show All to see all the options on the left

On the left you’ll have a menu, at the very bottom will be an option called Admin Centers

Expand this menu and click Exchange, this will open a new window displaying the ‘Exchange Admin Center‘ (if you don’t see it, make sure your browsers popup blocker hasn’t stopped the page from appearing).

On the left-hand menu click Protection

From the new sub menu at the top of the right hand section, click DKIM

Select your domain name from the list and then click Enable‘ on the right-hand side:

2. Determine Your Office 365 Tenancy Domain (AKA your onMicrosoft Domain)

To determine the DNS record you will need to setup for your domain name, you first need to login to your Office 365 account via http://portal.microsoftonline.com. and find out what the temporary domain name Microsoft gave you when you setup your account:

Click the menu button in the top left corner (it looks like a telephone dial pad)

Click Admin

Click … Show All to see all the options on the left /windows-xp-sp3-key-generator-online.html.

Click Setup to expand this option

Click Domains

You should see a domain that ends in onmicrosoft.com similar to this:

Note down the domain, in my example above mine is bobmckay.onmicrosoft.com.

3. Create CNAME DKIM DNS Records

Login to the panel used to manage your domain names DNS records – this will often be either your domain name registrar such as 123-Reg and GoDaddy or it could be your website hosting account (a cPanel, Plesk or CloudFlare account).

You can retrieve information about your domain names DNS using IntoDNS.co.uk and whois.com.

You need to create two CNAME records (not TXT records), based on the following format:

The VALUE part of the DNS record has two key parts:

1. Firstly, the value portion of the DNS record you create has my proper domain name in the first section but with the dots replaced with dashes (so bobmckay.com becomes bobmckay-com).
2. Next, it has the tenancy domain name we retrieved above in step 2 on the end.

Troubleshooting

If you receive the following error message:

Strictly speaking this error means either the DNS records haven’t been configured properly or they haven’t had time to propagate but when I forced refreshed the entire page, the error suddenly went away so don’t trust repeatedly clicking the ‘enable’ link!

What's the latest advice on DMARC, DKIM and SPF for Office 365 tenants?

I have configured SPF records with the Office 365 include for all domains that I manage as a minimum.

I have configured DMARC records in 'Monitor' for a few recent tenants recently, but I am yet to roll this out for all domains/tenants.

Generate Dkim Key Office 365 Email

I have not configured custom DKIM for any tenants - I know that Office 365 has Default DKIM Signing configured (which is based on the default tenant domain name that you are given with all new tenants).

Microsoft recommend configuring DKIM if;

• You have more than one domain in Office 365
  
• You're going to set up DMARC too (recommended) - I can only assume DMARC doesn't work correctly with default DKIM don't work, hence the need to configure custom DKIM records?
  
• You want control over your private key
  
• You want to customize your CNAME records
  
• You want to set up DKIM keys for email originating out of a third-party domain, for example, if you use a third-party bulk mailer.
  

Tdu 2 serial key generator. I'm trying to work out if I should set up all three of the above for all the tenants I manage? None have more than 35 users so I would classify them as SMBs.

I think if you're going to configure DKIM, you should configure DMARC to give instructions to recipient mail servers on what action to take if SPF and DKIM fail.

I have looked at DMARC reports in the past (never received a forensic report - I don't think many mail providers generate these yet?) and cannot make much sense out of the detail included.

Any advice appreciated.
