Summary

This guide helps you troubleshoot and resolve: Can I Keep My Current Email Address When Moving to Microsoft 365?. Follow the steps below to fix the issue.

Common Causes

Yes. You can move your existing email addresses to Microsoft 365 without changing your domain or interrupting your client communication. This guide walks you through migrating from legacy IMAP, POP3, cPanel webmail, or shared generic logins to Microsoft Exchange Online, including how to set up shared mailboxes, signatures, calendars, and improve email deliverability.

Quick Fix Steps

1. Verify you own the domain you want to use with Microsoft 365.
2. Add the domain to your Microsoft 365 admin centre and update DNS records.
3. Create user mailboxes and shared mailboxes for addresses such as accounts@ and sales@.
4. Migrate existing emails and contacts from your current provider.
5. Update MX records to point to Microsoft Exchange Online.
6. Configure email signatures and shared calendars.

Detailed Instructions

1. Add and Verify Your Domain

1. Sign in to the Microsoft 365 admin centre at https://admin.microsoft.com.
2. Go to Settings > Domains.
3. Select Add domain and enter your business domain name.
4. Choose how you want to verify ownership, typically by adding a TXT or MX record through your domain registrar or DNS host.
5. Complete the verification steps provided by Microsoft.

2. Create User Mailboxes and Shared Mailboxes

1. In the Microsoft 365 admin centre, go to Users > Active users.

4. Select Add a shared mailbox, enter the email address and name, then save.
5. Add members to the shared mailbox and assign permissions such as Send as or Send on behalf as needed.

3. Migrate Existing Email

1. If moving from cPanel webmail, IMAP, or POP3, use the Microsoft 365 admin centre migration tools or a third-party migration service.
2. Connect to your source email server using the server address, port, and credentials provided by your current host.
3. Select the mailboxes to migrate and schedule the migration during low-usage hours.
4. Monitor migration progress in the admin centre and verify that emails, contacts, and calendar items arrive correctly.

4. Update MX Records

1. Once mailboxes are created and migration is tested, go to your domain registrar or DNS hosting provider.
2. Locate the MX records for your domain.
3. Replace existing MX records with the Microsoft 365 values provided in the admin centre under Settings > Domains > [your domain] > DNS records.
4. Save the changes and allow time for DNS propagation, which can take up to 72 hours.

5. Configure Email Signatures

1. Sign in to the Exchange admin centre at https://admin.exchange.microsoft.com.
2. Go to Mail flow > Rules.
3. Select Add a rule > Apply disclaimers to create an organisation-wide email signature.
4. Configure the rule to apply to all messages and enter your signature HTML or text.
5. Users can also set personal signatures in Outlook desktop under File > Options > Mail > Signatures, or in Outlook on the web under Settings > Mail > Compose and reply.

6. Set Up Shared Calendars

1. Open Outlook and go to the Calendar view.
2. Right-click My Calendars and select Add Calendar > From Address Book.
3. Select the shared mailbox calendar and add it to your view.
4. In Outlook on the web, right-click Other calendars, select Open calendar, and enter the shared mailbox address.

7. Prevent Emails from Landing in Junk Folders

• Add SPF, DKIM, and DMARC records for your domain in your DNS settings.
• In the Microsoft 365 Defender portal, go to Email & collaboration > Policies & rules > Threat policies > Anti-spam.
• Review and adjust spam filter policies to ensure legitimate internal and client emails are not marked as junk.
• Ask clients to add your sending domain to their safe senders list if messages continue to go to junk.

Troubleshooting

Emails Not Received After MX Change

• Confirm DNS changes have propagated using an online DNS lookup tool.
• Verify the recipient address exists in Microsoft 365 and is assigned a licence or shared mailbox.
• Check the Microsoft 365 Message Trace tool in the admin centre under Mail flow > Message trace.

Cannot Send from Shared Mailbox

• Ensure the user has Send as or Send on behalf permissions assigned in the admin centre.
• Restart Outlook after permission changes are made.
• In Outlook on the web, the shared mailbox may need to be added manually under Folders > Add shared folder.

Migration Stuck or Slow

• Check that the source email server allows IMAP connections and that app passwords or modern authentication are enabled if required.
• Reduce the number of concurrent mailboxes being migrated.
• Contact your current email provider if connection errors persist.
