Office 365 Hybrid Deployment With AAD Connect - If On-Premise Active Directory Went Down. RRS feed

  • Question

  • Hello just a quick question,

    Say I have a Hybrid Deployment configured with my on-premise Active Directory to my Office 365 tenant & Azure AD with AAD Connect (DirSync)

    I want to know what happens if my On-Premise AD goes down would my users still be able to access their Office 365 Accounts? (Having SSO Configured & SSO not configured would both configurations allow access to their Office 365 Accounts?) - Or are the passwords cached in Azure AD from when you configured SSO if so the users will be able to log in to their accounts.. also if SSO wasn't configured I am assuming they will still be able to access their accounts because the passwords will be different.

    If someone can answer this as soon as possible with maybe a Link to a Description regarding it in detail it will be extremely helpful.

    Thank you very much,
