Frequently Asked Questions
When will my team be migrated?
Migration is being rolled out in waves by office location. Wave 1 (London) completed 17 March, Wave 2 (Manchester) completed 14 April, and Wave 3 (Edinburgh) completed 1 May. Wave 4 (Remote workers) is scheduled for 12 May. You will receive an email notification at least one week before your migration date.
Will I lose any emails or files during migration?
No. All emails, calendar events, contacts, and OneDrive files are copied to the new environment. Your old mailbox remains accessible in read-only mode for 30 days after migration as a safety net.
Do I need to change my password?
Your existing password will continue to work. However, you will be prompted to register for Multi-Factor Authentication (MFA) on your first sign-in to the new environment. See the MFA registration guide for step-by-step instructions.
What should I do if I cannot access my email after migration?
First, try signing out and back in. If the problem persists, clear your Outlook credentials (see the Outlook setup guide) and sign in again. If you are still unable to access email after these steps, log a ticket and we will prioritise your case.
Who do I contact for urgent issues outside business hours?
For critical issues outside business hours (17:30–08:30 weekdays, weekends, and bank holidays), call the IT Service Desk on 0800 123 4567. For non-urgent issues, log a ticket and the team will respond on the next working day.
