Preparing your email migration
Migration Timeline & Cutover
Your migration will occur in phases:
- Pre-Migration Preparation
- Mailboxes are created on the new platform
- Initial data sync may begin
- Cutover (Switch to New Platform)
- Your domain’s email routing is updated
- New email begins arriving on Thexyz Email
- Final Sync
- Any remaining messages are transferred
Important:
- The exact cutover time will be communicated in advance
- You may be able to log into the new webmail before all mail appears
Step 1: Access the New Webmail
You can log into the new platform here:
- New Webmail: https://mail.thexyz.com
- Classic Webmail: https://webmail.thexyz.com
You may log into the new webmail before cutover, even if your email data is not fully visible yet.
Step 2: Prepare Your Devices
- Do not remove your existing setup until cutover is complete
- Prepare new configurations in advance where possible
- Use Application Passwords for devices and email clients

Step 3: Email Client Settings (New Platform)
Use the following settings for all devices:

Port: 993
Encryption: SSL
Outgoing (SMTP)
Server: smtp.thexyz.com
Port: 465
Encryption: SSL
Username: Your full email address
Password: Your mailbox password or Application Password
Step 4: Outlook Setup (Recommended)
If you use Microsoft Outlook:
- Create a new Outlook profile (recommended)
- Do not modify your existing profile
Tips:
- Hold CTRL when opening Outlook to select profiles
- You can configure the new profile before cutover
- Do not set it as default until cutover is complete
Step 5: Mobile Devices (iPhone / Android)
Mobile devices typically do not support multiple accounts for the same mailbox.
Recommended approach:
- Wait until cutover is complete
- Remove the old account
- Add it again using the new settings
