Connect a Microsoft 365 or Outlook mailbox to Commslayer using Standard setup. No daily sending limits.
Time required: about 10 minutes
Setting up something more specific?
-
One alias only — support@ goes to Commslayer, your other aliases stay in Outlook. Microsoft 365 alias setup → (15–20 minutes)
-
Aliases across several domains — support@yourstore.com, support@yourstore.se, and so on. Microsoft 365 multi-domain setup → (30–60 minutes)
Before you start
- Admin access to your Microsoft 365 account
- Access to your domain's DNS settings
- An email address on your own domain, with a mailbox you can forward from
Step 1: Create your inbox and add DNS records
Come back here once your records have verified.
Step 2: Enable external forwarding
Microsoft 365 blocks external forwarding by default. Nothing reaches Commslayer until you turn it on.

Step 3: Redirect your mail to Commslayer
-
Sign in to Outlook on the web
-
Go to Settings → Mail → Rules
-
Create a new rule: apply to all messages → Redirect to → paste your Commslayer forwarding address
-
Check Stop processing more rules
-
Save the rule
Use Redirect, not Forward. Redirect keeps the original sender's details, which is what lets Commslayer match the conversation to the right customer.
Step 4: Test
Send a test email to your support address from a different account. It should arrive in Commslayer within a minute or two.
Only new mail forwards — your existing history isn't imported.
Microsoft quirks
-
"Your organization does not allow external forwarding" (550 5.7.520) means the outbound spam policy in step 2 didn't save. Go back and check it.
-
If your DNS is managed inside Microsoft 365, your records live under Settings → Domains → your domain → DNS records.
