Finally I've found a solution to this problem. It seems to be related to a registry problem. The AppData shell reference was incorrect on my system.
Here you can find the solution

The post from JeePee
1. Close all running programs
2. Click on [Start] » Run
3. Type "Regedit" and click [OK]
4. Open the following folder:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
5. Now choose Edit » New » Expandable String Value
6. Enter "AppData" as a name
7. Double click the new entry
8. Enter "%USERPROFILE%\Application Data" in the value data field.
9. Close the registry editor

Warren, This is what worked for me. Running Windows 7 x64 in conjunction with Outlook 2010 on an Active Directory Domain with Exchange locally.
Control Panel, User Accounts, Manage your credentials
Under Generic Credentials you will see your Outlook Saved Password. My belief is the password saved in this area is invalid. Remove the saved password and log on to Outlook 2010. It did not prompt me for a password as it used my already authenticated domain login and password.
Thanks,
Ray

Ray,
Thanks, that worked great for me too. Using win7 x64 ent. with outlook 2010 on AD domain with exchange 2007 running on our network.

I didnt try anyone elses solution, but Rays solution worked for me on Win7 with Outlook 2010 in a Exchange 2010 SP1 environment.
Thanks Ray, I was over complicating the issue and looking in all the wrong places, you saved me a lot of time.
Finally Microsoft fixed this in the Office 2010 SP1 update today. I did the update and since then outlook 2010 do not ask for password, you must check the save password box. I restarted the computer several times and it worked every time with no problem and without doing anything.

What worked for me after no other proposed solution was possibly the simplest fix: Delete Outlook Mail Profile in Control Panel> Mail, and recreate.
Apparently when I used Easy Transfer, something essential did not make it, or got corrupted. Manually recreating the Mail Profile solved the issue.
I have searched all over for a solution to this crazy problem and some of them highly technical and poorly explained and were for outlook 2003 and 2007. Finally I found this less than 2 minute fix that works. http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/ This is not my fix but glad to pass along something that actually works. Give Kudos to the "how-to-Geek" and post in other forums to help out all your frustrated friends.
1. Close outlook!
2. go to my computer and then paste this into the address bar. %userprofile%\AppData\Roaming\Microsoft\Protect
3. rename the very long file name S-1-5......etc by appending "-old" to the end of the existing file.
4. now re-open outlook and you may be request for your password. If so enter it and check the remember password box
5. now go back to %userprofile%\AppData\Roaming\Microsoft\Protect by searching in windows explorer or my computer and you should see the renamed long named file and a brand new long named file.
This should work for you. If not, then do a shut down and reboot a time or two. Then try reopening outlook 2010 and your problem should be fixed. Save this link: http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/ because this problem is likely to recur sporadically because of microsofts pushed updates that cause more problems than they solve. Turn off automatic updates so MS cannot keep screwing up your system and snooping.
This fix was explicit for Vista but worked fine for me on Windows 7 64 bit running outlook 2010. Post your results to see if it works for others please. I know everyone is tired of chasing their tails on this problem and even posted fixes have been so vague that you need to be a software engineer to follow them. If you have other fixes for this I know everyone would appreciate people posting all the steps from the beginning to end and assume that we know nothing at all. Post all the paths and explanations in simple terms please.
I hope this helps.

Another excellent solution.

This thread is great. I had spent tons of time trying various suggestions from other threads that were useless. Here in this thread are three or 4 easy solutions that anyone can follow. Thanks to everyone!

I used this solution after rebuilding our SBS 2008 64 Bit Exchange server with AD on it from an Acronis backup. Restore worked fine for everything but exchange. After trying to re-key the servers cert and endless firewall tests and countless other things; users still were getting prompted for passwords. iluvit posted solution worked the first time on my network.
Thanks!

I tried the suggestion of uninstalling the affected email addy and reinstalling - didn't work. Installed Microsoft Connector - didn't work. Tried clearing out password and re-entering - didn't work. Deleted my Deleted Items (trash folder - had 3k emails from just 6 wks.) to almost nothing, closed email program, reopened it - SUCCESS!!!! You have no idea what a difference this fix has made in my life, Thank You!!!!
I just wanted to say "thanks!"
I had a user that just started today to get the password prompt for some unknown reason. She has at least 1,100+ emails in her Deleted Items box and after deleting them all; she was able to send emails just fine! :)
I am replying as I have additional info for Windows 8 and Outlook 2013. I would think this would also apply to Windows 7.
When you have multiple email addresses and Outlook prompts you every time you reboot your computer, this is the solution:
Control Panel, User Accounts, Manage your credentials, Windows Credentials
Under generic credentials modify ALL saved outlook passwords and make sure that the user name does NOT show your domain name. So it should NOT read domain\user. Only put username (without domain) and password, save and reboot to test.
This worked for me with Windows 8 x64 and Outlook 2013. Hopefully this will address Outlook 2010 as well for those of you that could not find a solution.
Thanks,
Ray

After changing a ton of outlook settings, deleting the user's account profile on outlook, deleting their domain profile from the effected computer, trying to fix the registry, deleting stored credentials, etc.... almost everything else I found something that FINALLY worked for me after over a year and about 12 different users being effected.
in the past I would just give up after much frustration and upgrade them to Office 2013 but that gets very expensive especially when I have 57 other users that could potentially run into the same issue.
Here is what I did.
- back up the user's data. log out and log into local admin
- delete the user from the local registry
- repair Office 2010 through control panel/programs, restart
- have user log back in with their credentials to make new local profile. recover their backed up documents. log out and log back in as local admin.
- install hotfix KB2597011
- restart computer
- install hotfix KB2583935
-restart computer
- log in, open outlook and setup user's account.
Some of these steps may be skipped as I didn't find the hot-fixes until after I repaired office, however I am just providing what I did in the process to end up with a working outlook again.
Some things unique to my situation that may or may not help.
- I noticed some of the computers have Office2010 32bit installed on 64 bit machines.
- Some of the users were swapped over using a profile mover program when we moved to a domain environment.
- For me this always happens when the user's passwords expire and they have to log in to the portal to change it. Then outlook starts with the repeated prompt for passwords. It is always computer specific and nothing but what I provided above has worked other than re installing windows 7 and then office or upgrading to office 2013.
1. Close outlook!I have used this process on a number of occasions to fix this problem and it's worked every time. I have no idea why it happens every now and again (I think it goes wrong when my PC is offline and can't connect to the Exchange server) but it happened with Outlook 2010 and still happens with Outlook 2013 and this method has always fixed it.2. go to my computer and then paste this into the address bar. %userprofile%\AppData\Roaming\Microsoft\Protect
3. rename the very long file name S-1-5......etc by appending "-old" to the end of the existing file.
4. now re-open outlook and you may be request for your password. If so enter it and check the remember password box
5. now go back to %userprofile%\AppData\Roaming\Microsoft\Protect by searching in windows explorer or my computer and you should see the renamed long named file and a brand new long named file.
