I can't send or receive new emails and when i open Outlook, I get this "Enter Your Network Password"  which is prefilled with that info. How do i fix this?

Original title: Cant send or receive emails
I'm getting an expired certificate message for one of my directory services (LDAP/SSL) each time I open Outlook.  I've verified that the server in question is presenting a valid certificate, and there is no sign of this expired cert anywhere in my keychain, so it appears that Outlook is caching this somewhere.  Where, and how do I clear that cache or delete the bad certificate?

Paulesso,

 

Question: I have IE8 and whenever I open Outlook, I can see the emails but can't open them nor can I select any emails for action i.e. move or delete.  Please advise.

 

Sincerely,

Tony Garcia

When I try to email a file from an open program, Outlook starts to open and then closes. I am able to manually open Outlook and then paste the file or link. I don’t remember changing anything that would have caused this to happen. This has been an ongoing issue for about a month. Thanks for everyone’s help.
Recently when I open Outlook, the box that reads "Setting up identity" indicates a name other than mine  

When I click on "About Outlook" a different name, other than mine, is listed in the box under "This product is licensed to"

When I print an email message, the name of the same person (not mine) appears in the header

I am puzzled and don't know who this persons name got on all those.  The mystery person has never been to my house or touched my computer. 

Is there a way I can delete the mysterious name and add mine?

Help!

I cannot open Outlook. Might be related to a power failure while it was open in the background as it was working prior but when I came back to the machine and found it was shutdown I restarted the system. After re-start the Outlook issue has come up. I see from other threads that the solutions mentioned don't apply with Exchange Server use so not sure what to do. I'm using Mac OS X Version 10.7.5 
I am using Outlook 2011.  My identity file is 1.36 gigabytes, but when I open Outlook, it is not showing any of my contacts or emails.  Help!
