How to check if someone is invisible in gtalk ?

It will be interesting to check if one user is really signed out from the Google talk or he is in invisible mode. Please note that this trick works only if the user-id is online from gtalk and not from gmail. I will explain the reason why it is applicable to gtalk only.

Steps to check whether one user is offline or invisible in google talk

The steps to check whether the gtalk user is online or offline are:

1. Log on to gtalk or gmail

2.Go to chat settings (In gmail click on options under chat contacts)



3. Select the button Never save chat history




4. Save changes

Now you can send an Instant Message to a gtalk user and if the user is really signed off ,you will get an alert like "User did not receive your chat".




If the gtalk user is invisible we will never get this alert.

Note: This trick will not work if the user is chatting with you from gmail. Even though he is offline the offline chat will be saved as emails in the users account.
