Exchange 2010

Dear Experts,

In my organization windows server 2008 is configured along with the domain. Exchange 2010 is also configured. We configure new user through Exchange 2010.

Password policy in the domain is:-
Minimum password age =not defined
Maximum password age =not defined
Password meet complexity=yes
Minimum characters =6

Also in the user properties I have selected password never expire.  

Also users are directly login to the mail through the browser.  

My question  is: - most of the users complain that password is not working after sometime. When I reset the password still the users are not able to change the password to the new one. It says password not meeting the minimum requirements or sometimes they can change without any issues.  
Why most of the users are complaining about the password.

Please help

There is no firewall as far as I am concerned. Will cross check once again with the network team.  There is also no Single Sign on Feature.

You need to set 0 for min and Max age. Not setting a value is not a viable.  

The default domain policy has a setting of 45 or 60 days
So if this still exist this setting is also being applied.

I would check and make sure there is only one GPO that has the password  setting.

Setting the Value to 0 disables password expiration.

So minimum & maximum password age is currently set to :-NOT DEFINED .

So if i make "0" the password issue will be solved. Shall I make it to "0".

Waiting  for your reply.

I assume you don't have fine grained password policy. Secondly, default policy will always have below policy defined by default.

Minimum password age
Maximum password age

Goto user OU via gpmc.msc and check which password policy is applied.
yo_beeDirector of Information TechnologyCommented:

Yes Set them to 0.  
As stated in my reply they need to be set to something and also make sure that the Default Domain Policy has this setting Not configured or your you will have a conflict and might not get the desired results.

Hi ,

I have set the Minimum password age & the Maximum password age to 0 from not Configured (old one).

Also there is no other gp for the policy


yo_beeDirector of Information TechnologyCommented:
So let's see what happens.

Note the computers need to update or you can run

GPupdate /target:computer to manually initiate update for the computer configuration.
