Question about Outlook Express

It happened to me that a message from the Microsoft Outlook is suddenly popped up while I wasn't doing none Outlook is Hotmail is connection, in this same computer then asking myself is to introduce the password for my Outlook Hotmail Account j********** Email address is removed for privacy ***. Then is was that myself introduced my password for this Outlook is message that was displayed in order to comply with the request. After I did so, then, my Outlook is Hotmail is account displayed inside it, but as I wasn't expecting that the Outlook was into opening my account by this request, nor was I doing anything nor before nor after regarding the Outlook is software is, as for example, nor connecting, nor connected, and/or no nothing is at all, better said is, then I just tried/proceed to close the Outlook Hotmail is but the operation also reacted odd as it didn't got close/disconnected from my strangely accessed account, ever, therefore is that myself is just have the option left to turn off the/this same computer that myself is was using which is this one, one of my partner's/friend's, so myself is ended up doing this/that way is was. Myself is must now say as well that about my way is that I found that really strange as is that myself is living with my partner's/friend's since more than a year now and is for myself then also to say first that as my partner's/friend's shares her both computers' (two laptops that she have of her own is) with myself is. Occurred to myself is that several weeks ago myself is while myself is was trying to send some emails from the Outlook is Hotmail is of this same one computer that (but still exist the possibility it was from the other's computer/laptop that my partner's/friend's allows myself is to use and that also have on it installed it the Outlook Microsoft and there is that as well is myself is sometimes is have used it before is, the Outlook Hotmail in it with myself is own same email account is j********** Email address is removed for privacy ***) I am at now using for at the time and/or while sending/submitting this information to yourself is at this Microsoft's Hotmail's OPEN FORUM is,  and by the way as well as in the other computer is that I also use of course, and that as aforementioned is that belongs to my partner's/friend's also I repeat, (I don't have computer of my own since we are living together is but the one my partner's/friend's allows me to use) the emails that I found as matters is, as is now involving two emails is by the way delivered from my Outlook's Hotmail account's while was I using this one particular computer's I am using now as during the day before yesterday is was and in the past weeks or months ago/before is what I mean I don't know (is as I also could be of the two computer is weren't these sent at the time and then appear as two of the one that weren't sent is several weeks ago were sent instead/other on the occasion that is was the event after  one was sent to both are, my partner's/friend's account and to another account I know at viernes, 27 de septiembre de 2013 12:31:59 p.m. (FRIDAY 27 OF SEPTEMBER OF 2013 12:31:59 p.m.) and the other one email that was sent to a known lawyer/attorney at viernes, 27 de septiembre de 2013 12:31:56 p.m. (FRIDAY 27 OF SEPTEMBER, OF 2013 12:31:59 p.m.). I can just now say that it was never supposed to happen is. What can I do to spot what caused this as is an uncomfortable situation and an odd situation that I never think I experienced it before in my life, as I don't recall ever have realize this happens at least is, and as now is that at least is I must tell at least one of the recipients, about the fact that it was a mistake and/or an error and/or an unfortunate event that I didn't provoke nor myself is wanted to happen nor myself is could avoid as it was supposed to occur is but at another time which is means is several weeks ago is? Do maybe these recipients received  it several weeks ago and now due to the problem herein described therefore twice is?
