Constant Password Prompt in Outlook 2007

[JAbercrombie]

Outlook 2007 has suddenly started prompting me for Network User/Password when
checking mail. Have not added any new software or made any changes. Worked
fine for months. Monitoring about 6 e-mail accounts from various servers and
am prompted on each account. Have tried all 3 suggestions in Knowledge Base
doc 290684 (create new profies - deleted old ones / bring up in safe mode -
disabled all COM addins / used regedit to remove key under Protected Storage
Provider key). Also downloaded hotfix as reccomended in KB doc 956531.
Nothing has worked. I've had this PC for months and everything was working
fine until last Thursday afternoon. I'm at my wits end. I've read all the
other posts pertaining to the situation, but none of the suggestions have
worked. Thanks

I have been experiencing the same problem with Outlook 2003 and have tried
resolutions found in Microsoft Knowledge Base Q290684, which was also of no
help. I hope someone finds an answer. I am very close to switching to
Mozilla Firefox.

I know what you mean.. We are in IBM business partner and we sell/reccommend
systems with Microsoft software all the time and it's more than frustrating
the total lack of support you get from Microsoft. Anyway - my situation did
change and I actualy got Outlook to work again. How it happened is
unfortunately typical of solving MS product problems. Late Yesterday I
downloaded Office 2007 Serivce Pack 2 and IE 8. I immediately started having
problems with IE8. It was giving me a message that the default search
provider file was corrupted. Now - I had Outlook and Internet Explorer
broken so I just went home.. This morning I started to try to fix the IE
problem. I googled Default Search Provider Corrupted and got a hit. I found
a section to change a registry key and low and behold it actually fixed IE
(except I can no longer use my home page) PLUS my e-mails started coming
without having to re-enter the passwords. I changed home page to google and
now both IE and Outlook work.. Of course I haven't re-booted since them so
I'm crossing my fingers on what happens in the morning.. Below is the thing
I did that seemed to fix two totally unrelated problems...

All,

I have had this issue since I installed IE8 on my XP Pro SP2 laptop. I just
did this and it fixed the issue for me.

1.Make sure IE 8 is closed then navigate to registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User
Shell Folders

2.Add a new “Expandable String value†inside the above mentioned key with a
value name of “AppData†and a value data of “%USERPROFILE%\Application Dataâ€.

3.Reopen IE 8 and see if you still get the error message.

This solution has been described in these groups before. See

What's not really known is why that particular registry key disappears, but
it's a key that every extant version of Windows needs.
