Active directory users and computers email address tab missing for some users

what is ur question?

First Organization (Exchange) --> Recipients --> Recipients Policies --> Default Policy --> Properties --> e.g. SMTP = abc.com

Because you must let the Exchange Mail server to know what domain name hosting in there. Then it will create the email address on tab when new user account setup.

I hope it can help.

TRY this
First Organization (Exchange) --> Recipients --> Recipients Policies --> Default Policy --> Properties -->E-mail addresess(policy) then double click SMTP

Ok - sorry if my question was not clearer - here is the problem:

When you open up a users within 'active directory users and computers' console some have the 'Email Address' tab and others do not have it. One use I need to configure already has multiple aliases but now I cannot see them to modify them because the tab is gone! Another user has the tab there, when I copy the errant user object to a new user the email address tab reappears - how's that for strange?.

because when ucreated the user u didn't create a email for them that is why u dont see the e-mjail tab. And also when u are in active directory users and computers click view choose advance feuture also.

 If u want to create mail for them right click the user / Exchange Task  then choose create a mailbox  then click next.
  one more thing u wont see the mailboxes in the system manage untill those user log on to the domain and open their outlook then  those mail boxes are created.

Good luck

Vahik - the user was already setup with email etc. including 3 aliases. I now need to change the alias but cannot because no tab exists to do this. Yet I can open the user above this one and they do have the tab.
Yes I have View -> Advanced on.

when u right click the user /properties do u have tab name exchange general then u see the alias there.

is that what u talking about please answer fast so I know

http://galileo.spaceports.com/~bingo007 if the above does not work

do this right click the user in question create mailbox click next then finish then see if that tab is there.

The ‘Exchange General’ Tab is there and the ‘Exchange Features’ tab. See this isn't even in  ‘Advanced’ mode and the ‘Email Address’ tab shows!

Like I said earlier the user already has a mailbox so that option is not available.

ok do more thing system manager/first administrative group/server/first storage group/mail box store/mailbox and in the right pane see if there is RED  XXXX on the users.

Vahik - there is no red XXXX on the users.

On testing furhter I found that when you remove the users Alias from the 'Exchange General' tab then when you open the users properties again their 'Email Adress' tab is gone too! So problem solved by me in the end - thanks for your help.

Thanks for the help - easier to give you the points than to try and delte the Q.!!

I think what you were lacking is the Exchange Server System Tools. You can get this off the CD you used to load Exchange.

This is obviously an old thread BUT i just hit this problem today.  Very same thing except the difference was that for me, adding an alias under exchange general did the trick.  The email address tab re-appeared after I added it.  I think this user initially had an alias which I deleted but I didn't realize it took out the entire email address tab.  Not sure why this happens
