In my Windows Live client I've always had two email accounts. One was a Cox account, the other a Gmail. I've had both of these accounts for years in the Windows Live. Just a few weeks ago I kept getting the "need login" boxes but also I couldn't send or receive my Gmails into the Windows Live client. I also would get another box stating that "couldn't complete request - send or receive Gmail". I did some checking and found out that Google has made some recent changes to their email security protocols and these protocols don't consider programs like Outlook, Windows Live, etc. to be secure enough for their Gmail program. In order to get the Windows Live to work without the pop-ups I deleted the Gmail account and added another Cox account to my Windows Live. All worked fine until a few days ago when the pop-ups reappeared. For the last couple of days though I haven't experienced any pop-ups. Like many companies, it appears that Google wants us to use just their product. Through some searches I found that there are a few companies that offer email clients that can handle multiple email accounts and are compatible with most email services. Some of these email clients can be downloaded for free.
If you have any email accounts other than Cox (Gmail, etc.) and you are using Outlook, Windows Live, etc. you might check if this may be the problem with the pop-ups and the inability to send and receive emails.
