Hybrid Exchange and autodiscover
Hi matthew want,
If you are not using any mailbox on-premises and you do not need any on-premises autodiscover feature using your on-premises autodiscover, you can change it to Office 365.
Hi matthew want,
If you do not have any mailboxes in on-premises, you can change the autodiscover to Office 365, you only need to change it back if you need to migrate mailboxes on-premises or use the autodiscover to use in Outlook and Mobile.
I am facing the same issue. Exchange hybrid with all our mailboxes in Office 365.
Are you saying delete the local autodiscover DNS records?
I have 2. Autodiscover.ttaf.co.za and autodiscover.ttaf.local.
Both of those records point to my on-premise exchange server.
Recently we renewed the third party certificate on this server but I forgot to include autodiscover.ttaf.co.za in the certificate subject alternatives names.
Now staff members are getting certificate errors even thou their mailboxes are hosted in Office 365.
Any advice?
I thought about creating CNAME records in the ttaf.co.za and ttaf.local internal DNS zones and pointing them to autodiscover.outlook.com. Do you think that would resolve the issue?
Thanks for the reply Nuno. I get what you are saying about mailboxes moving back to on prem but don't get the last part where you say 'or use the autodiscover to use in Outlook and Mobile'?

Thanks for clarifying.
