Question about Outlook Express

Could you please help with the following issue?  I have a paid subscription to windows live mail (ie formally Hotmail and now outlook.com) and am unable to send an email with more than one photo in it. I have had this problem for the last few weeks since Sky-drive was changed to One-drive. 
 
Solutions Attempted: I tried the 'fix-its' associated with some of the related forum threads and other solutions as well, including the following: I have checked and have confirmed that my pop settings are correct and that my firewall settings are not to blame.  I registered the correct dll files related to SSL and checked SSL, smpt, pop, and port settings, etc and these are all correct. I checked windows live communication policy settings in the registry and there are no issues with registry keys, etc.  I also removed my account and re-added my account and uninstalled/re-installed Windows Essentials, etc, removed all Windows Live registry keys and old email before reinstalling... and all of these attempts were  to no avail. The problem is still not resolved after trying all of the aforementioned solutions.

The problem occurs when sending an email with more than one photo... It gets stuck during the step of creating an album on One-drive... ie it is unable to upload the photos to one-drive for sending... I was able to do send more than one photo the very week before Sky-drive was changed to One-drive so I do not know if there are some different settings, etc... My father who lives out of state and has a completely different Windows Live paid account and is a completely different ISP,  etc, and also uses windows 7 called me for help with the very same issue... My son who also uses Windows 7 and windows live mail on his notebook computer (ie outlook.com) is also having the same issue ... ie not able to send more than one photo either as an attachment or as a photo album via the Windows Essentials Desktop Client.. 

Please note that I am able to send an email with 1 photo... but am not able to send more than one photo via the windows essentials client.  I am however able to send more than one photo when emailing directly from the server -( ie logged on to my account directly from the IE11 as well as the Firefox 29 browser window).  But when using the  Windows Live Client on my Windows 7 desktop computer I cannot send 2 or more photos via the photo album or as attachments in the same email. The email gets stuck in the process of creating a photo album on One-drive when trying to send an album.

Up until recently -- a few weeks ago -- I have always been able to send photo albums via the windows live client. I have changed no settings on my computer or on the Windows Essential Client since that time.. Then one day I tried sending an email with a photo album consisting of more than 1 photo and the email got stuck in my outbox. I tried sending more than one photo as an attachment and the email got stuck in the outbox. I tried sending more than one attached PDF documents and the email proceeded to be sent as usual. I tried sending one photo as an attachment and the email proceeded to be sent immediately as normal... Then I tried once more to send 3 photos as an album and the email got stuck in my outbox and was never sent...  The 2 other people I mentioned above tried this same test and are also able to send 1 photo but not more than 1 photo... This seems to be a problem uploading/syncing between the windows live mail client and Onebox on Windows 7.

Is there some way to resolve this issue quckly?

Thank you
