Outlook prompts for username and password intermittently?

Two domains, and each in a different forest. A.com and B.com have a forest trust. Exchange 2003 is installed in B.com.  Users log on to workstations using their A.com AD accounts.  Permission is fine. Their AD in A.com accounts have full access to the mailboxes in B.com. Intermittently, a user will be prompted for username and password when he/she tries to open Outlook. Sometimes, this pop-up box comes up when Outlook is running. When that happens, the user will just enter A.COM and password, and the pop-up box will be gone. What's up?

Hi all,

Do you guys have any idea how to configure "Always prompt for username and
password" under UI whenever we launch the microsoft outlook 2003?
What I meant is using GPO to mass-configure to all of the clients thru
production DC.

I cannot find any entries for Microsoft Office GPO -

Do you guys have any idea to "enabled" always prompt for username and
password thru GPO? TQ very much.

I am looking to configure the .prf file to place a check in the box "Always
Prompt for UserName and Password" box for both Outlook 2003 and Outlook
2007. I have read the prf Whitepaper & thought I had the settings correct,
but it will not take when applied.

Any help would be appreciated.

Thanks

I am having an issue with Outlook 2007SP2 and Exchange 2007 on an SBS08
Server. The outlook client will prompt for username and password multiple
times when outlook is opened. It does not matter what you type in the
password box it just keeps prompting. After you hit OK (even with no
password) three times the prompt disappears. It will then randomly reappear
when outlook is left open for a long period of time.

The issue is happening on (2) workstations (XP Pro and Windows 7 Pro) and
both machines are on the same LAN as the Exchange server. Neither machine is
configured to use RPC over HTTP both are in cached mode. There are several
other Outlook 2007 clients that function normally and all the Outlook 2003
clients function fine.

I have attempted to configure the profiles manually as listed in KB
http://support.microsoft.com/kb/923579
I have attempted the hotfix as listed in KB
http://support.microsoft.com/kb/956531 but it states the product type is not
the expected product for this hotfix,
I have attempted the registry key import from a working machine as listed
in KB http://support.microsoft.com/kb/321652 and
I have uninstalled reinstalled and service packed with no success.

Any help would be appreciated.

Thanks in advance

I have one OWA in my environment and ISA 2006.  I am running into an issue where I am getting prompt for username and password when I try to connect by http://servername/exchange.  I am on the same network as the exchange server and OWA.  Why am I getting prompt for username and password internally?

Thanks

My users are experiencing some intermittent issues. When they launch Outlook, they will be prompted for the username and password. After closing and re-opening it, it works. Why?

Hi

I run Exchange 2003 SP2 with all updates, with Outlook 2002/2003/2007 with
or without updates.

Some users get prompted for username and password every time they start
Outlook, why?

I have unchecked the "Always prompt for logon credentials" under acount
settings security. tryed every setting of Logon network security nothing
helped.

Anyone who can recomend a fix for this?

thanks in advance

Andersen.

Using outlook 2003 and Exchange server 2003.
Created a new user account.
User logs on and launches Outlook, a logon box appears asking for username
and password.
These are provided and are correct but the box keeps appearing over and over
again. If you cancel it outlook closes.

Has anybody experienced this problem before and knows how to solve it?
Thanks

I've installed windows 2008 r2 and exchange 2010.
rpc over http installed, exchange certificate created, outlook anywhere
enable with ntlm authentication

Outlook 2007 sp2 client works well in tcp, but when I test the connection in
http it prompt for username and password and it doesn't accept any entries.

Owa works fine without error certificate so I think that the certificate are
ok.

What I can try?

Thank's

We've got a number of users when working in Outlook Keep getting prompted for their username and password. When we've set up our test account, and logged in with it, we've been unable to replicate the problem. However, our user's are connecting remotely with a VPN set up to the Exchange 2K server.

Is there any reason why this is happening?

I have a user who is using Outlook 03 in cached exchange mode, and is
connected to a 2003 Exchange server.
Everytime He opens outlook it is in the "offline" state. When he unchecks
Work Offline, it then prompts for username and password. User types username
& password, but it keeps prompting. It recently just started doing this.

Things I have tried.
*User logs into OWA fine with same username and pasword just fine.
*Unchecked Work Offline, closed outlook and restart and it still starts in
"Work Offline"
*User has access to all the network drives, intranet, etc... that he should
have access to, but username and password do not work when prompted in
Outlook.
*I have verifed that "automatically detect connection state" is selected.
*I have verified that "Always prompt for username and password is not checked.

Any suggestions.


I have just upgraded from exchange 2007 to 2010 each role on separate server. Desktops running Vista or Win7 with outlook 2007 or 2010, while running outlook keeps prompting for username and password if don't enter credential loose mailbox connection.

Exchange 2003 OWA with SSL. My users supposedly to login using
domainusername, but some of them forget to put domain in front of the user
name and they still can login. Whenever they logout of an OWA session, they
get prompted for username/password. Since entering the password will not get
rid of pop up window (credential) without adding domain in front of the
user name they will cancel the session. Now they can log in again without
credential. Is this a bug or I am doing something wrong. How to prohibit
users to login without entering domain name in front of the user name and
why this is happening?

Any idea

Thanks,

John

My users keep getting prompted for their username and password when they try opening an attachment
in OWA 2003?

Any ideas?

I don't know what's going on with 2 sites of my network once users outlook
keeps asking for domain/username and password when the clients opens the
outlook and then passed a few minutes asks again.

I've already check all outlook and exchange configuration and I don't know
what do...

I hope someone can help me!
Thanks

Hey folks,

1 forest/ 2 child domains / 2 exchange 2003 servers, one in each
domain, 2 admin groups.

When scheduling a meeting from a user in domain A and inviting users
from domain B, I can see the free busy information without any
problem.

When scheduling from domain B and trying to invite a user from domain
A, it always prompt for a username and password. There is no way to
see free busy even if i enter a domainAusername. The popup windows
is coming from the exchange server in domainB.

I AM LOST...

The FB public folders are not replicated. Both FB are configured with
default permissions.

Any thoughts!

Thanks!

Interesting problem.
Starting an Inter-org Exchange migration.
Steps so far:

1.) Using ADMT to migrate user accounts with SID history into target domain
2.) Using Exchange 2007  PowerShell script to migrate mailboxes from source domain (Exchange 2003) to target domain mixed 2007/2003.
3.) Moving mailbox from CityA Exchange 2007 to CityB's Exchange 2003 Exchange server using the mailbox move wizard.
4.) Changing users Outlook profiles (using kix script) to point to new Exchange 2003 server in CityB.
So far so good.
BUT!

The user account in the Source Domain and Target domains have same username and password and SID history (which should be a good thing).
Problem is we need the users in the Source Domain to still log in using their SourceUsername account in the morning.
Then start Outlook and attach to their TargetUsername mailbox.
Now... since the usernames and passwords are the same it seems to just log straight into Outlook without asking for credentials (Outlook 2003 and XP).
They can send/receive e-mail fine, but when they want to connect to another Target Domain users Calendar they get the following error:
"The Calendar Folder could not be found"
So, you're thinking replication of Free/Busy time issue right!
BUT
If I go into the Advanced Mail options pages (in Outlook) and check the "Always prompt for username and password" check box (security tab) and log out and back in.
Lo and behold it asks me for a username and passsword.
I enter in the TargetUsername account and password and NOW.. everything works.
SO.
What I am thinking is that Outlook is somehow getting fooled and is using the Source account and not the Target account when logging in to Outlook.
It's not erroring because the usernames and passwords are the same.
The problems occur with the "Folder could not be found" because the Source domain account doesn't have rights in the Target domain Exchange org.

With me so far?

NOW, what I want is for the user only to have to enter in their TargetUsername credentials the first time they open Outlook.
Hoping for a check box that says "Save my password" or something so the next time they log on they don't have to log in twice (Unless their profile is deleted, in which case it would be expected anyway).

A couple of answers to questions I can see coming.

1.) Why move them back to Exchange 2003.
A: Because they don't have nay 64bit hardware yet. Plan is to migrate them to Exchange 2007 when it arrives.

2.) Why don't you just grow a pair and migrate the whole user account and mailbox and get them logging in to the Target domain.
A: I'm a big chicken! and its 5000 users, and they are big chickens too.
Will tackle Exchange first then get onto troubleshooting domain migration issues later.

Can anyone come up with a better way to do a Inter Org Exchange migration, but keep the users initially logging on to their old domain?

I'm having an issue with Outlook 2003 running on WinXP Pro SP2 in an
Exchange Server 2003 enviroment. Two people with laptops have the
same issue. When they connect using Cisco VPN client (ver
4.8.01.0300) from home, Outlook prompts for username and password.
Entering the correct info does not help -the prompt just comes back
even after multiple attempts. The VPN client has no problem
connecting and staying connected as they can access other network
resources. This problem just began occuring a few days ago. Outlook
is not set to prompt for a password. When they are connected to our
office LAN there is no issue. Also, the issue does not occur when
using a wireless broadband internet service - only when using thier
ISP's at home (wired or wireless). This is not an ISP issue as I had
one of the people take an identically configured spare laptop home and
it works fine. I have un/reinstalled the VPN client several times and
checked thier Outlook profiles to make sure they are the same as the
other users here. Any ideas? Anybody seen this before? If this is
not the correct group for this issue, please advise me of the correct
group. Thanks!

In regards to the previous question " can't receive in OE and getting the
prompt for username and password ".

I am asking this on behalf of a friend who has this issue. The person is
blind and uses a JAWA program to access his e-mail through OE. We've checked
his email access through the ISP provider webmail and all works fine there so
there is no issue with the server.

As for giving you the error verbatim, I was listening to it over the phone
and all that got from the error was " prompted for username and password " .
There was no error number.

The person had this issue over a week ago with the same prompt but what had
happened is when he called in for technical support the password was changed
and he was unable to get it changed for OE. I assisted him in getting that
password changed thinking that would resolve the issue but it seemed that the
password wasn't retaining in OE. What happened in the end was the OE account
was deleted and we rebuilt the account from scratch. All the settings were
checked as per his ISP provider to be correct. That seemed to resolve the
issue up until today.

The customer is getting the same prompt for username and password and to his
knowledge no changes have been made. Again his webmail is working fine. The
operating system is XP.

The biggest hurdle for this person is being blind and having to rely on his
trainer to help him with it at this time.

Is this possibly a corrupt OE program or a conflict with the program he uses
( JAWA ).
