Outlook Office365 Work Account Error 0xCAA70007

Outlook 365 0xCAA70007 error message connecting to onmicrosoft Office365 account: You'll need the internet for this 0xCAA70007

Hi,

I'm facing an issue with accessing my onmicrosoft Office365 account with outlook. Whenever I open outlook in windows it shows the prompt "You''ll need the internet for this". The message says we couldn't connect to one of the services we need you sign you in. Please check your connection and try again.

The error code is - 0xCAA70007

The outlook works fine in the browser and internet connection is working.

I tried repairing office and also removed outlook credentials.  I have also uninstalled office and now the client will not even load.

• In Explorer, navigate to  C:\Users\%Username%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC\Microsoft\Crypto\TokenBindingKeys\Keys
• Delete the Keys in the folder
• Relaunch Outlook - Keys are re-created automatically.

Dell Vostro 3500 loses/lost WiFi-connection / drops out of WLAN and does not re-connect because of overheating

After being on for a few hours, my wifes' laptop lost WiFi Connection and direfused to reconnect. Leaving it off for some time then, WiFi was working fine again.

How-I-fixed.-it:
Monitoring the problem for a few days I recognized that the downside of the laptop was very warm at the time it lost WLAN connection. I remembered having troube with this system in the past due to overheating because of a dusty fan assembly, as described in a previous post: http://how-i-fixed-it.blogspot.de/2013/05/laptop-dell-vostro-3500-turns-itself.html

I disassembled the system and found the heat exchanger filled with dust. I cleaned the whole fan assembly and since the system is much cooler now, also the WiFi is stable.

log4net AdoNetAppender stops logging / does not recover if database connection is lost / database is down, ReconnectOnError

I use the Apache log4net AdoNetAppender to log information from my application into a SQL database. In case, the network connection to the database is lost or the database is down for some reason, the AdoNetAppender quits logging (forever) to the database and does not recover even if the database is online again.

How-I-fixed-it:
I found the right hints here:

Add the tag:

to the log4net XML config file:



   

Keep in mind, that it then tries to reconnect to the database until the connect times out. This blocks the thread of the application!

You can add:
Connect Timeout=1 to the connectionString  property to Limit the blocking to 1 second:
   
   
   
  


   
   
   
   
  

How to change the name of a network connection in Windows 7

Windows 7 automatically names network connections like Connection 1 etc. I want to assign a name to the network connection myself, but there's no context menu or link in the network and share center. How i fixed it: Click on the network type symbol next to the name of the network at "Active Networks" in the network and share center. A dialog box opens to allow entering a name for the network and to choose the symbol to be displayed. Here are the screenshots for my german OS:

Click on the network symbol to open the dialog:
