Problem: Migrating to and/or from Microsoft
Solution:
- Don’t use a Global Admin account when setting up the BitTitan part, use a service account
- The service account should have a mailbox, Global Reader permissions and NO MFA
- Turn off MFA for the entire account if need be, follow instructions from: https://www.torontohelpdesk.ca/blog/office-365-mfa-is-turned-off-yet-it-still-prompts-for-it/
- If you get an error: your migration failed while checking destination credentials. One or more errors occurred

- Delete the client secret (for the app)
- Create a new client secret
- Make sure you copy the Value and not the Secret ID
- Wait 20 minutes
