Everyone needs breaks from sitting in front of their PC after a stretch of time, and you probably take some too. However, your contacts won’t know when you’re taking a break, and might try to contact you when you’ve stepped away.
To find out if you missed any IMs, check your lock screen. This is the screen that displays when you lock your PC. If you’ve set Skype for Business (Lync) as a lock screen app, the Skype for Business (Lync) icon with an asterisk will display on this screen to indicate missed conversations.
After you unlock your PC, check the Skype for Business (Lync) tile on the Windows Start screen. Under Things you missed, the last three interactions─IMs, calls, or voice mail messages that were received since you last used Skype for Business (Lync), are displayed. The IMs include new invitations and updates to active conversations.
After you unlock your screen and open Skype for Business (Lync), there will be a number on the History tile indicating how many new IM invitations you missed since you last used Skype for Business (Lync). Select the History tile to see these invitations. Each missed IM in the History screen is highlighted until you select it. The History screen also displays the IM conversations, calls and meetings you had in the past, up to a maximum of 50.
To respond to a missed IM, select it, type your response, and press Enter.
New messages in active conversations
A conversation is considered active as long as the delay in the IM exchange is less than 10 minutes. A response that is received 10 minutes or more after the previous IM is considered a new conversation and Skype for Business (Lync) displays it as an invitation to a new IM conversation.
If the Skype for Business (Lync) window is hidden when the new message is received in an active conversation, a notification displays for a few seconds. If you don’t respond to it then, the new message is considered as missed. The next time you open the Skype for Business (Lync) window, a highlight is shown on top of the window to indicate a new message.
To see the new message, swipe in from the top or bottom, or right-click the screen if you’re using a mouse. The bar on the top displays tiles for all your active conversations and calls. The tile for the conversation with the missed message is white with a yellow highlight. Select it to see the missed message.
Turn off new message notifications
You may want to stop getting notifications of new messages from your active conversations during important meetings or presentations. If you do, turn them off from the Skype for Business (Lync) Options panel. Here’s how:
Open the Settings charm. Swipe in from the right edge of the Skype for Business (Lync) home screen, and then tap Settings.
If you’re using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and click Settings.
Scroll down the list of options to Notifications of new IMs in active conversations.
Move the slider to the left to turn off the option.
Tap or click outside the Skype for Business (Lync) Options panel to close it.
Can’t see your missed IMs?
If your PC loses its connection to the Exchange server, information about your missed IMs won’t get sent to Skype for Business (Lync). And, the following error message is displayed at the bottom of the screen:
Skype for Business (Lync) can’t connect to Exchange. You might not have the latest history, voice mail, contacts, and Skype for Business (Lync) Meetings.
The information eventually gets sent to Skype for Business (Lync) when your PC re-connects to the Exchange server.
