outlook 2013, o365 in hybrid and direct access.

[chazzy2501]

I'm seeing an issue with remote users (teachers going home) where outlook 2013 is unable to connect. I see a certificate warning that lists the local domain exchange server... all mailboxes are in the cloud. now I can only assume that the duff certificate is being provided by the local exchange server as its "exchangeserver.domainname.local" and exchange certs can't use the .local so of course it's invalid. I'll assume this is a direct access issue, although I'm seeing strange results from my autodiscover. (just a redirect to office365 ip addresses.)

 

 

edit:

 

ok so the cert source has the "exchangeserver.domainname.local" instead of the "mail.internetdomain.sch.uk"

has the certificate run out?

[chazzy2501]

no the cert is good but is for the external name not the internal.

well, I turned off the local exchange and this didn't help. When I remove the direct access features (on guest internet) outlook works fine. maybe a dns issue?
