I have a MX record on my internal DNS pointing to mail.global.frontbridge.com. should this be changed? I am have tons of issues with people not being able to connect through outlook. Support team seems so overwhelmed I am not getting call backs this
needs to get fixed!
MX records are for mail delivery, sending mail servers who need to know how/where to connect to deliver a message. As Jeff points out below Outlook requires an Autodiscover DNS record, which is picked up by Outlook and tells Outlook where to go in
order to connect to their mailbox. Creating an autodiscover.customDomain.com which points to autodiscover.outlook.com will instruct Outlook to connect to Exchange Online 365. EXO365 will ask who the person is and after entering credentials outlook.com
will do an MBX lookup and redirect Outlook one last time to the users final location where the online MBX resides.
This is a change from BPOS where the Sign-In Client (SIC) manually configured the Outlook autodiscover setting via the registry. In Office 365, Outlook configuration is no longer an option and the DNS Autodiscover record is now a requirement when supporting
Outlook clients connecting into EXO365 mailboxes!
