There are a few prerequisites that need to be in place before this can happen. 1) You have to be on a Domino 8.x server, the person you are trying to recall the email from will also need to be running on a Domino 8.x server 2) You have to have the mail 8.x template in order for the option to be available 3) Your administrator has to enable the feature (it’s enabled by default).
If all of the above is setup then all you need to do is go to your sent folder, select the email you want to recall and click the “Recall Message” button.
There are some other settings that come into play that would need to be addressed with your Lotus Notes Administrator. For example, if a message has already been read your admin can deny the message to be recalled. If the email is older that a certain number of days the recall can also be denied.
