Your first Microsoft 365 sign-in and handover
Start after your licence activation has been confirmed. Your Microsoft work account and your FernByte shop account are separate sign-ins.
1. Use the confirmed work account
Open Microsoft’s Microsoft 365 sign-in page and use the work account confirmed during onboarding. Use an existing password, or the private initial-access method agreed during assisted onboarding. We do not publish or email tenant administrator passwords. Contact FernByte if the login name or secure handover is unclear.
- Check the account belongs to the correct business tenant.
- Complete any required initial password change yourself.
- Do not use a personal Outlook.com account unless Microsoft explicitly asks you to choose the work account linked to your tenant.
2. Register your security information
Follow your organisation’s Microsoft prompts to register an approved MFA method, such as Microsoft Authenticator or a passkey. Keep a recovery method allowed by your administrator. Approve only sign-ins you initiated, and tell your administrator immediately about unexpected prompts.
3. Open the apps your licence includes
Basic provides web/mobile apps and business services; Standard and Premium also include desktop Office apps. If a licensed desktop app still shows a personal or old work account, check the signed-in account before buying another licence. The features and device support depend on your assigned plan.
4. Check your business email and files
If setup or migration was booked, work through the agreed handover checklist. A new licence alone does not copy old email, move files, configure your custom domain or enrol devices into management.
- Send and receive test email and check the agreed aliases/shared mailboxes.
- Open OneDrive and Teams with your work account and check the intended business is selected.
- Confirm migrated items against the migration report, where applicable.
5. Keep control of your tenant
Your business should retain an authorised administrator and recovery arrangements. Review service access and remove temporary permissions when they are no longer needed. Cancelling an optional support package does not remove your Microsoft tenant or cancel an annual licence commitment.
Common questions
Why can’t I install desktop Office with Business Basic?
Business Basic does not include the desktop Office apps. Use its web/mobile apps or ask about a suitable licensed plan before changing subscriptions.
What should I send if sign-in fails?
Send the error text, time, affected work email and order reference to FernByte. Redact private data from screenshots. Do not send passwords, MFA codes, recovery codes or payment-card details.
