Constantly asking for authentication in MS Outlook

Heyas,

I am part of a network every so often when I open ms outlook it's asks for username and password to log about 10-15 times, then the message goes away.

This happens once every 3-4 days.

I have reset my password in exchange I still have the same issue.

Any ideas.

Thank you.

Hi,

Please try the following:
1. Close outlook
2. Open %userprofile%\AppData\Roaming\Microsoft\Protect
3. Rename the folder to OLD at the end
4. Restart machine
5. Outlook will ask for the password, enter the password and click remember credentials
6. Problem should now be solved

Hope this helps!!!

Are you using Exchange 2007/2010 with Outlook 2010 by any chance?

If this is the case are you using self-signed certificate on your Exchange?

Did you buy any certificate for your exchange/OWA?

To verify you can just go to:

https://localhost/owa

on your Exchange server and see what certificate it's using.
