0365, exchange

use the https://testconnectivity.microsoft.com/ to diagnose the problem.. report back any errors.

Is the computer or user account in Active Directory only allowing certain users to logon to it.  (Logon Restrictions).  I have seen where if you do have logon restrictions set and you don't have your ADFS servers listed as allowed to logon to office will fail to locate and authenticate.

where to check  logon restriction.

I am attaching the image the person who is having issue

can it be  a UPN mismatch, if so what needs to be checked

this user felipejesus@clearchannel.com.br is not getting autodiscover

what should I check

user name is felipejesus@clearchannel.com.br

user is on o365

Check Active Directory Users and Groups and go to the user account -- right click and say properties -- go to the account tab --  and click on "log on to" make sure all computers is selected.  

Also does web access work?  What else have you tried?  Is it just 1 user and no one else?

his machine is fine only , all users are having  the problem is in remote server, to remote users

Checking this domain's MX record it doesn't seem it's pointing to Office 365. Are you 100% certain that this domain's mail system is hosted on Office 365?

The MX is pointing to this company "mxa-001b1801.gslb.pphosted.com"

If you're certain that it's hosted in Office 365 then you need to change your public domain's Autodiscover Cname record to point to autodiscover.outlook.com the issue should be resolved automatically .

Also you need to create the other Exchange online DNS records like msoid.clearchannel.com.br

And finally correct your MX records if you are not receiving Emails.

where do you check clearchannel.com. br mx ?

mxa-001b1801.gslb.pphosted.com this is our mx server

he cannot configure his outlook on remote server

his outlook connectivity works fine from his machine

but cannot configure outlook on remote server

pphosted.com is NOT office 365

where do you check clearchannel.com. br mx ? http://www.mxtoolbox.com

Pramod1,

Please re-explain the issue you are having.  It is hard to troubleshoot your problem with all this mis-information?

Apparently your Exchange is not on Office 365 then. it's on PPhosted.com! you'll need to verify that your Outlook anywhere is configured properly and that you have a public certificate that includes both your OWA SAN and autodiscover.clearchannel.com.br

my mail box is on o365
 I have iHeartMedia.com it points to mxa-001b1801.gslb.pphosted.com

my outlook is working fine

Outlook anywhere is configured properly and that you have a public certificate that includes both your OWA SAN and autodiscover.clearchannel.com.br - where should I check taht

one of your mx records is blacklisted.
you may be an open relay
http://mxtoolbox.com/domain/clearchannel.com.br/

Your email service provider is "Proofpoint" not Office 365

I need to get the hosts file checked on that server,a s issue is coming from one server only

i need to know right language as autodiscover.clearchannel.com.br is pointing where in hosts file?

can you let me put correct words

Could you please send a screenshot of your web mail? If it's Office 365 OWA so we can all make sure that you're using Office 365 not anything else.

Second it's not the Hostfile you'll be checking. it's your Public DNS! I am attaching a screenshot of what your current autodiscover config looks like.

i was told to check hosts file on that particular server as public dns mentioned above si correct

we checked  in RCA

what ip that hosts file has for autodiscover

Exchange Online
Type       Priority       Host name       Points to address       TTL
MX       0       @       yourdomain.mail.protection.outlook.com       1 Hour
CNAME       -       autodiscover       autodiscover.outlook.com       1 Hour
