Autodiscover works on one computer but not another

Question

I have a user uuu@OO .com. When I try to use autodiscover via Microsoft Outlook for 365 on the user's computer it fails. When I try this same thing, with the same user info, on my computer autodiscover works just fine.

Can someone help?

Hi @Mike Collier ，

When I try this same thing, with the same user info, on my computer autodiscover works just fine.

Did these 2 computers have any difference(such as Internet, whether they belong to a domain or the version of Outlook client or others)?

Considering it could work normally on other computer, in order to further confirm if the issue is related to the Outlook client or computer, it's suggested to test the autodiscover via Windows Mail client on user's computer. If the issue also occurs on Windows Mail, the issue may be related to the computer, it's suggested to switch to other internet and check your DNS settings.

If the issue indeed occurs on Outlook 365 client only, it may be related to your Outlook itself.

Did it display any errors when you failed to login on Outlook? If it's possible, please provide us with a screenshot of your error(please hide your personal information for security).

As I know, we could use Microsoft Remote Connectivity Analyzer tool to test the connectivity between Outlook and server, it's suggested to test if your account would display any errors there.

Also, in the point of Outlook client, we could troubleshoot some issues via SaRA tools, which works by running tests to figure out what's wrong and offers the best solution for the identified problem, please try to use the tool to check if it could work for you.

Answer 2

Hi @Jade Liang-MSFT - It does work with Windows Mail; it does not with Outlook.

I have uninstalled Outlook, deleted the Outlook directories - the program and data directories, reinstalled Office 365 and it didn't change anything. It doesn't give me any errors.

I have run SARA and it doesn't find any errors and takes me through the Autodiscover process again which of course fails again.

I have run Microsoft Remote Connectivity Analyzer which fails on one part about Autodiscover not being set up properly. However, that makes no sense to me since Autodiscover works on the Windows Mail client and works on Outlook on my computer.

Other ideas? Thank you for your response.

Answer 3

Some screenshots as evidence of the issue.

oic-1 is the result when trying to create the new account directly in Outlook
oic-2 - oic 8 are the results of using SARA.
oic-9 are the results from running Microsoft Connectivity Analyzer.

Any help is appreciated.
