Yesterday I send an IM to a friend who was on-line, but he was not. He told me that he was off-line at that time... Do anyone has any idea of how I can check if a friend who is "on-line" is not? And also, how can I do the same if I want?

I know that if you try to use the web version of yahoo messenger it doesn't always log you completely out.  I had to start up full messenger & log into that ID to get my other account to show as offline after I used the web version of messenger.  \n\nIt's just a yahoo quirk.  And yes, Beta could very well have something to do with it.  When yahoo made a big change 4 or 5 years ago...messenger was screwed for months.  People would stay visible online for weeks at a time even when they weren't online.  If yahoo doesn't keep their servers in sync with each other, this will happen.

It is removed from YOUR sent folder, not her inbox.  It will still be in her inbox when she logs on, you just won't be able to see when she reads it.

It is almost certainly not due to your conversations being watched.  If an IM Content scanner is in use you would have absolutely no idea since it would be on a spam port off a switch somewhere in your network\n\nYour problem is most likely due to some network oc PC issue.

she might not have permitted to let you see her online status on Messenger... but try to email her. If that dosen't work... Then try removing her completely out of your contact list and add her again.

yeah ive gotten that too. it is put in place so after a certain amount of IMs that you send, you cant send them for awhile. i think its to make sure you arent harassing people, or being obnoxious, or abusing their free service by mass sending messages. so after you send a whole bunch in a short period of time, they limit you for a little while.

You can't. That's the point of it being 'invisible'.\n\nThat person can contact you if they want, and then you'll know they're on-line (that is - if you're not invisible...)

Are you sure they went offline immediately?  Theres an updated messenger now, maybe you should uninstall the older one and download the newer one.

I have not recieved an offline message for over 18 months!!!!  I am a network engineer myself and have done numerous tests to prove it is on Yahoos end.  They ignore all messages and will not fix the problem.  If everyone having this issue would email them with help requests about this issue they may fix it.  I googled the issue and there are a couple forums out there describing the issue.  All in all yahoo will be losing my business soon as I will be selling any stocks I own from Yahoo or any joint companies such as Verizon.  Customer satisfaction is number one and 18 months is way too long.  Things I tried to prove it is Yahoo!\n\n- logged in as id1 sent message to id2 (id2 is known to be a good account).\n\n- logged in as id2 and message sent from id1 recieved.  sent message back to id1.\n\n- logged in as id1 and no message recieved.\n\nall in all this proves it is on their end and not any network settings, especially when this scenario can be repeated with almost any version, network configuration, isp, etc.

Trust your instinct.  This sounds like a scam.  You can right click on the name to delete _and block_ him.  If you just delete him, you won't see him, but he will see when you are on.  If you block him, he won't see when you are on.  Reporting him to yahoo/MSN or to the computer fraud squad of the Police may also be a good idea.

make sure you checkmarked the "save this message for later use" box when you create the away message and make sure your preferences are set up to "show away message when idle", also, if you respond to any IM, the away message will turn off unless you have the box checked to allow you to respond to messages ... if all else fails, uninstall and reinstall the software.  make sure you dont have earlier copies of AIM on your system that could interfer or corrupt your installation and make sure AIM is not running when you do the install

This site claims to check whether someone is really online.\n\nI have never used it but must be worth a try...\n\nhttp://blockchecker.msnfanatic.com/

I don't know what they used to have, but Yahoo! Messenger doesn't have this feature now, for user privacy. If it's really your friend, though, you can always just send an IM asking which room he's in.

There should be a way for you to block the other user.  I did it today.  When you put your mouse over each individual name does a box pop up? If so, on the bottom of the box does it say "you appear online to this member"? or something else if something else use the drop down box to change it to the setting you like.  OR  Try right clicking on the persons name and go to "stealth settings"  and click on Permanently offline.  If you need more direction let me know

nope you just need to know the AIM id. No e-mail , no online, no permission.\n\nYahoo IM requires permission, which you can only get when the other person is online!\n\nit's in the menu "add buddy" or something

If the person you are sending the email to is using an internet based mail (such as Yahoo, MSN, GMail, etc.) then there isn't anyway to check for this....although I do remember seeing something about requesting a return reciept. However, if they have a non-web based mail then you can usually check the status of the message, and see if they recieved it.

i think, regardless you are in his contact list or not, if he doesn't use option "only accept IM from contact list", he'll see the message, unless he hast login for sometime. no way you can know if you are in his contact list or not.  call him up and ask him?

If you missed any messages while you were offline, when you sign in again there will be a thing that pops up that says offline messages, you can read them from there, but once you close that you cant see them again unless you have your messages archived.
