Catch-all email not supported with Microsoft 365
Catch-all email are used to deliver mail when the address wasn't spelled correctly or the recipient doesn't exist. This can result in unwanted mail, including spam, being delivered as well. To prevent the risk of phishing attacks and other security threats, Microsoft 365 doesn't allow catch-all email.
If you used catch-all with Workspace Email, they’ll no longer work after your move to Microsoft 365. However, Microsoft 365 includes several features you can use instead after you've transitioned from Workspace Email. Choose which feature works best for you.
If you know the email addresses going to your current catch-all, use any of the following:
- Alias: Create an address that sends all mail to another inbox of your choosing. For example, if your address is firstname.lastname@example.org, and you set up the alias email@example.com, all mail sent to either jane@ or sales@ will automatically go to firstname.lastname@example.org. Here's how to create an alias.
- Distribution group: Communicate with a group of people, such as a department or team working on a project. Instead of having to include each individual recipient, you can send mail to the distribution group and every member will get it. Here's how to create a distribution group.
- Shared mailbox: Allow a group of people to read and send messages from a common email address. For example, you could set up the shared mailbox email@example.com so employees who have access could receive and respond to its messages. Here's how to create a shared mailbox.
If you don't know the email addresses going to your current catch-all, follow these steps:
- Sign in to the Exchange admin center. Use your Microsoft 365 email address and password (your GoDaddy username and password won't work here).
- Go to recipients, and then select shared.
- Select New.
- In the new window, enter the following:
- Display name: The name of your shared mailbox. This is what recipients will see when they get mail from this address.
- Email address: The name of the email address before the @, like contact for general inquiries or sales for your sales team. Select your domain from the list after the @.
- Apply this rule if: Select The sender > is external/internal > Outside the organization > OK.
- Do the following: Select Redirect the message to > these recipients > your shared mailbox > OK.
- Except if: Select add exception > The recipient > is a member of this group > allusers (your dynamic distribution list from step 10) > OK.
- To get the most secure and reliable email, update your account to Exchange for all devices.
