Question about Outlook Express

In the Home Tab, lefthand column bottom. When I click on the 'contacts' icon window comes up but I get a 'not responding' message along with full hourglass. Remains unresponsive. I have to go into Task Manager and terminate the app then restart Mail.

I have 7 different  email accounts with my current ISP, which is the allowed limit, and I use WLM for email in my PC.  All these accounts are configured to the same settings--on the Advanced tab they all have the same ports listed--993 & 465, and they all have the SSL boxes checked.  On all the accounts I have the setting for server timeout set at 5 minutes.  Everything is identical for all of these POP3 email accounts, and I have no problem sending and receiving email with 6 of them. 

However, I'm having problems with the 7th email address--I keep getting Error Message 0x800CCC0E, and I've been all over the internet looking for a solution, but none so far.  The error reads as follows:

"Unable to send or receive messages for the Comcast XXXXXX account. Header download for the 'Caretakers' folder did not complete. The connection to the server has failed."

"Windows Live Mail Error ID:  0x800CCC0E"

"Port 993"

"Secure(SSL):  Yes"

I have lots of folders with my other 6 email addresses, and they don't interfere with sending or receiving email.  It's just this one email address, with this one folder, which is causing this problem.

I don't know of any other incoming port, so it stays at 993.  I've changed the outgoing port from 465 to 587 with no improvement, so changed it back to 465.  I've shut off Windows Defender email scanning as recommended in this support Forum.  Nothing seems to work--I still get this incoming email problem with this particular email address, because of this particular folder.

I've been to my ISP for help, but they just tell me it's a Microsoft problem and I need to pose the problem to your Forum, which I am now doing.

Any suggestions for correcting this incoming problem with this one email address, with this one particular folder?

I've been using Movie Maker for some time.  Why am I suddenly getting a message to purchase Movie Maker when I try to save my move...after hours of working on a video???

So I've never had this problem before... I had a large movie I was working on, many edits that I don't think I'll be able to duplicate. Well, Windows Movie Maker crashed and my project became corrupted. I'm devastated and about ready to cry.  If anyone could help me at all I would be so grateful! I had saved it half an hour before the crash without issue... I don't know how to restore to previous versions, it doesn't give me any options for that. Any help is appreciated, thank you!

I am currently having a reoccurring issue with my Windows Live Email address.  Every so often when I try to send my mail, I get something like this and I will not be able to receive or send mail:  

----

An unknown error has occurred.

I have used the information from this site to change my sever ports and the like, but still now dice.  This is incredibly frustrating; I am almost 90 years old and no one has been able to explain to me properly why my email address keeps doing this.  How do I fix this?  And how do I prevent this from happening again?

I can get emails but some of my contacts arrive in my junk mailbox and I can't unlock the junk mailbox.

any suggestions?

when I split a video, and delete one of the sections, the file size gets larger when saved.  Is the common?  Shouldn't the file size be reduced?  Do other editors have this same trait?
