Hello, Actually it Mail the application of a PC that will seek information on the server of your ISP. When the connection is made, messages are transferred from the server messaging application on your PC and therefore are not available for a second transfer. Two possibilities: Either you-check your email directly on the server and not using the messaging application on each PC. -Or, when you read your messages on PC1, you contact the and receptionists on PC2. Attention, so that it works, do not do "send/receive" but only "send" button, close the mail and open that of PC2, otherwise you will immediately receive the messages sent on PC1 with PC1.
must be the first PC when Outlook open Go to Tools -> Accounts -> Right click on the email account -> Properties -> Advanced -> Check "Leave a copy of messages on server " Repeat this operation on other accounts if you have several. Beware the 2 nd PC will delete messages from the server, thus leaving Outlook open all the time on the first PC to leave messages on the 2 PC
