I recently started getting "mail could not be received at this time" error.The rest of the message reads: "The server for account xxxx returned the error: Logon failure: unknown user name or bad password. Your username/password or security settings may be incorrect. Would you like to retry entering your password?

All of my credentials are correct and when I enter the information it will connect for a few seconds but then ask me to enter credentials over and over. If I choose "no" it disconnects my session.

I've tried deleting the account and rebuilding, restarting my computer, and deleting my keychain. Nothing seems to work.

Thanks for any help!
I've checked many sites and I go to options, but I can't find this "message tab"  they're talking about.
I just would like to get back the old Instant Messages I had merely two days ago.
Thank you~
Original Title: "can't open outlook for mac" 
Hi - can you please help.  Outlook was working fine until today - when I click on the icon i get a message "Microsoft cannot be opened because of a problem" 
  The key error message seems to be: 

Dyld Error Message:
  Library not loaded: @rpath/mbukernel.framework/Versions/14/mbukernel
  Referenced from: /Users/USER/Documents/Microsoft Outlook.app/Contents/MacOS/Microsoft Outlook
  Reason: image not found

Am not  technically minded at all - grateful for any help in layman's terms - many thanks 

Original Title: "Message. Category"
If I would like to unassign a category from a message, how can I do it?
I keep getting this message and another.  5.5.0 invalid address.  I know what i did wrong, but now every time i hit send and receive, I get the 2 errors.  Everything seems to work, but I want to stop getting the errors.  How do I delete the original e-mail that has the wrong address or domain name?
Thanks, Peter
What is the function of the red exclamation point and the blue down arrow in the create new message tool bar?
Yes, Some one sent a private message to all my contacts and some as many as 5/6 times a week. Very frustrating as it is my business address. Though i am not personaly sending them, people think i am. What the **** do i do without haveing to create a new address.?????????????
Every time I sign in to hotmail, I get the message saying that my Hotmail account has no valid username and password. I am still able to sign in but why am I getting this message and how do I correct this?
On Exchange Server 2007 using MAC Office 2011 and keep getting this error message.  Don't see much help for the Error Code -19942 in searching.

My old disk crashed but I have my files backed up.  How do I import 'message rules' from my old WLM?  Right now, when I imported my mail, it all went into Trash and the new incoming mail is going into the Inbox.

 

What file do I need to find in my old mail?

 

Thanks
