Hi @dss ds ,
You could check the username format, depending on the settings it could be just USERNAME, DOMAIN\username, or username@keyman .com.

I am experiencing issues with logging on to EAC and OWA as users created
this is kinda wired one..
Under VM if I install Exchange on the same as AD/DNS (I know, not recommended, but its seems to be ok as a test environment), and I add user mailboxes from EAC, I can login in no problem
Trying to increase performance, I later decided to install AD/DNS on one VM, leaving Exchange 2013 for a seperate VM..
Both are running same Windows server 2008 R2, AD/DNS has 2 Gig, while Exchange 2013 has 8Gig
When I attempt to login to OWA/EAC via user, I get a loop (basically the same symptom as incorrect credentials, except there is no error. displayed"
How is this even possible when the only difference between the 1st and later methods is just DNS pointing rather than 127.0.0.1 ?
There is something a miss. and I do not think its just due to exchange being on a seperate VM that's causing this.
Any ideas ?
It seems to only affect Users created in EAC/OWA, as Administrator can access no problem
Tried this on Server (AD/DNS) as well as Exchange VM and same issue.. Only Admin can log in..
As I said, strange how this only happens when Exchange is on seperate VM..... so something strange is happening.

- Could you tell me whether exchange2013 is uninstalled from the original VM and then installed on the new VM, because some errors may be encountered when uninstalling exchange.
- I would like to know that you log in the EAC by the FQDN or the IP address (127.0.0.1) because different login methods may lead to different results.
- I noticed that you cannot log in to EAC/OWA through a user. Have you tried to create a new user to log in to OWA?
- By searching for some information , you probably would need to rebuild virtual directories. There are plenty of guides on the web on how to do it.
- If the above methods do not work, you can check whether the IIS configurations are correct, such as whether the correct certificates are bound to the default web site and exchange back end.
- And then can you check the application logs in the event viewer? When an error occurs, there will usually be an error and the corresponding event ID, so that I can further troubleshoot the cause of the fault for you.

2022-06-07T02:47:18.85+00:00 - No... VM's are seperate and not running at the same time.. Exchange is installed on both but exchange+AD vm (x2) are taken offline. Thus there is only one VM actually running when the issue is not there.
- even if it only accepts some and not all ? eg Admin ok, users not..
- Yes, just tried creating new user in AD,, but unable to login using it OWA and ECP
Will look into it.

2022-06-07T09:50:20.133+00:00 Hi @dss ds ,
I want to know whether AD refers to DC or something else? Are you migrating exchange from one VM to another as is , such as keep the same Exchange server name/IP address? As far as I know, This is not supported. I found an article about the problems encountered in server migration. You can refer to it to see if you have made the same mistakes.

2022-06-07T11:22:28.713+00:00 Active Directory refers to DC I'm not migrating anything,....
I have 2 servers:
1st server: comprising of AD/DNS, and Exchange 2013.
2nd server: VM same as 1st, BUT exchange is in additional VM (so just AD/DNS only)The reason i did this was this 2nd one, because i was trying to see easier performance wise, and more convenient for me, but i never expected this issue to crop up either
in both server (VM) cases, there each have their own DNS/AD, and before 2nd one is run, the other is shut down not to cause issues/conflict.
IP's are unique pointing to relevant servers, but obviously DNS on 1st server has DNS 127.0.0.1 because its also DC. while 2nd one has DNS pointing to separate.
Apart from that the server names are different as well... and everything clean installed, including exchange servers on relevant VM's
The issue of not able to login as users only affect 2nd setup, not the first.. So I cannot believe in a perfect scenario the reason i cannot login as user is because exchange in on separate server. Many companies in production do the same, so it must be unique to my issue only.
In both servers, i've compared virtual directory's in IIS, and all look ok...
Deleted user(s) in AD and re-added them also made no difference.. add user as well.Three are no errors in event log,, when it happens..

2022-06-09T07:38:18.547+00:00 Hi @dss ds ,
I want to confirm whether your two servers are in one domain or two separate domains and what does your DNS point to?
In addition , I hope you can provide the configuration of virtual directories in your IIS use the following cmdlet : Get-OWAVirtualDirectory | fl -

Please provide the certificate configuration and the screenshot you provided before cannot be displayed.
It is not recommended that you use an FQDN with “ .local “.This may also have an impact.
In addition , I want to confirm whether your two servers are in one domain or two separate domains and what does your DNS point to? It also helps me find out where the problem lies. -

2022-06-06T01:22:37.22+00:00 Its forms-based Domain/Username. Although this wouldn't explain why it only affects created users only as this is a global setting..
for, example Admiistrator can log into owa and ecp just fine
Checking under User on ECP, Outlook web access is "enabled", so still unsure why at this point.
I can log into Windows as User in AD just fine as well, so its exchange specific..
I'll keep this around, but at this point i'm liable to just set up another VM with it all on, so i can get on with what i need to do, while i sort this in addition. only because i would wanna know the reason.
Tried Chrome, Firefox and even IE
