OT: 800cccd3

I am using Windows Live Mail 2012. When I try using "delete all items " in either the deleted file or the junk email file I get an error code 800cccd3. I have to delete everything individually and I never used have to. Using charter for my internet service. My daughter signed onto her email using Outlook and this error has shown up ever since. Any suggestions?

We appear to have a dodgy connection with talktalk server - this has been happening for a few weeks - affecting random emails - but now we've completely lost the connection - and talktalk swear there is no problem their end. We get 2 windows - first one is "Log-on talktalk" with user-name and password all filled in and it says "Next time you log on you'll have to fnput your password." This window has appeared quite a bit but usually you could close down, go back in to WLM and all would be well - no window - tho' sometimes you had to wait till next day - or till Mon if it was the weekend. Re passwords, talktalk made me change it yesterday - I've obviously tried putting the new one in - no change.
The 2nd window is Windows Live Mail error message - which says that an incorrect password was entered - not true.
Any ideas, please, anyone? I know I can use Webmail but I use email a lot for various committees - folders etc - and WLM is also easier for me to read - I have macular degeneration.
What I want to do is to be able to tag my contacts (in my "All Contacts" list) so that when I receive new email in Windows Live Mail, email messages from my contacts show up so I don't have to scroll through so many "spam" emails. I use Windows 7.

outlook mail was taken from windows 8,so I am currently using windows live mail,would this transfer onto windows 10 automatically with existing emails and contacts.

Would like to simply export all windows live mail 12; Account settings, Folders, Calendar, and eMails to outlook 13.
Does anyone know how this can be done???
Up until recently Mail worked OK but since BT had remote access I have this problem and also occasionaly get a black box appear where the normal top right hand delete box should appear. Any solutions please>

When sending message, I receive message "This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed"

I am receiving this message on all emails I send from my hotmail account.  No other account is affected.

I am receiving the emails from all but when I reply the mail bounces.  The address must be correct as it is a reply. However to check this I have re-typed the addresses.

If I send from another address e'g' gmail there is no problem.

It started 2 days ago when I sent a message early morning. I then tried to send another message and this started happening. My personal opinion is a setting in either live mail or outlook but I cannot find where to change them.

Any help gratefully received.

need to change my user name and password for windows livemail 2012

I'm using the Windows 10 Ojtlook app to manage my Outlook account. But I only can see the most recent emails. Anything that's older than like a week simply doesn't appear.

Is the any setting to be able to access all my emails always?

Thanks
