Common Mistakes & How to Avoid Them

⚠️ Incorrect Email Format:
Use your full Microsoft 365 address (e.g. [email protected]), not an alias or user ID.

⚠️ Forgetting MFA Requirements:
If your organisation requires MFA, ensure your device is ready with the Microsoft Authenticator app, and your login method is up to date.

⚠️ Password Issues or Expired Credentials:
Check password validity by logging into https://portal.office.com first. Reset if needed.

⚠️ Attempting Manual Setup:
Manual configuration (IMAP/SMTP or Exchange settings) is not recommended. Use automatic setup unless advised by IT.

⚠️ Using Outdated App Versions:
Update Outlook on all platforms to ensure compatibility with Microsoft 365 features like conditional access, shared mailboxes, and modern authentication.

⚠️ Using Native Mail Clients:
While possible, native email clients (like iOS Mail or Samsung Email) may not fully support Microsoft 365 policies or features such as encryption and shared mailboxes.
