After I download and open Windows Live Essentials, I get the error message "error: 0x80040155." I cannot even download individual programs like Messenger and Photo Gallery.
I keep receiving this error message from Outlook:

Client tried to access nonexistent namespace. (Mailbox name should probably be prefixed with: INBOX.)

Have no idea about what to do
Hello, my name is Diego I'm from Brazil and I'm 13 years old ... my Windows Live Messenger is the 2011, I can not enter with an e-mail since Friday (17/08) I have two emails,1 I use other the not, which I do not normally use enter and what not ... the error is 8e5e03f9 help me ... please I do not speak English so if you have any error here sorry!

I woke up today seeing my msn kicked off because i was logged from another device as it said.

I already changed my password but I'd like to know if someone hacked into my account or was just some error.

Error Message
 I constantly get the error message: The server for the account gmail returned the error (ALERT). Too many simultaneous connections (failure) Your username/password or your security settings may be incorrect. Would you like to try reentering your password. I reenter my password and it keeps pooping up. How do I get rid of it?
I can't seem to connect on or off network to a brand new exchange server from a fresh install on a new mac... painful.
I get the error "Unexpected data was encountered" error code -17997 and not sure if I can really say much more.

Mac Mail works fine (to boot), and I've literally copy-pasted the user, server, etc from one to the other and outlook is still not functioning.

Anyone else? Is there some special "mac setting" that needs to be enabled on the server?

Running: Mountain lion, MS office for Biz, all updated and current. Permissions repaired, etc on my MBP-r.
Sorry, there seems to be a problem with Hotmail right now

After signing in to my hotmail account the front page will load, it will allow me to open Skydrive but not my email. 

This error message appears "Sorry, there seems to be a problem with Hotmail right now". 

Skydrive is still available, 

I am still signed in but unable to access hotmail from any terminal I have attempted entry. 

I recently, about 7 days ago, added Hotmail's app to my Android and am still able to access my email through it. The problem did not appear until yesterday, several days after adding the app to my phone. 

If the app is the cause would it not have been an issue immediately upon install and sync??
Still cannot resolve this error and now msn's site is not working. I'm going to have to give up trying msn messenger.

Error:

 Activation context generation failed for "C:\Program Files\Windows Live\Messenger\msnmsgr.exe".
Error in manifest or policy file "" on line . A component version required by the application conflicts with another component version already active.


Conflicting components are:

Component 1: C:\Windows\WinSxS\manifests\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4148_none_5090ab56bcba71c2.manifest.
Component 2: C:\Windows\WinSxS\manifests\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.1_none_e163563597edeada.manifest


I navigated to these components and the system won't allow me to delete either of them.
outlook (2011 office for mac version) pops out this error message, which stalls my ability to use outlook. 

it constantly asks me for my password, and although it gives me the option to save it in the keychain, it never does. 

this error keeps occurring since the latest two office for mac software updates that i diligently downloaded and installed. 

i reset the identity earlier today and the error still occurs twenty minutes later. 

any thoughts on how to deal with this? MS only offered their support after charging me $49 for a one-off troubleshooting over the phone... needless, to say, i am trying not to pay that outrageous fee. 

thank you for any suggestions.
