You set the screen resolution to Medium (125 percent of the standard dots per inch DPI setting) or Smaller (100 percent). You apply the June 2015 update for Microsoft Lync 2013 (Microsoft Skype for Business). In this scenario, a blank dialog box appears without any control button or contact in Lync 2013 (Skype for Business). Running Windows 10 v1703 OS Build 64 bit Skype for Business 2016 MSO (16.0.4738.1000) 32-bit. I've only experienced this with group shares (more than 2) and when I'm not the presenter. In my experience the chat works fine, until the presenter (or someone else in the group) shares their desktop and I just get a ghost outline.
Clearing Skype for Business Cache in macOS. Log out of and quit Skype for Business; Go to Finder; Press Command+Shift+G or click Go Go to Folder; Type /library and press Return; Delete the following bold files: Containers com.microsoft.SkypeForBusiness; Internet Plug-Ins MeetingJoinPlugin.plugin; Logs LwaTracing. The MAC client that is being worked on, NEEDS to have Persistent Chat included. The fact that the PC side has had this for 5+ years, while the MAC has not, is VERY SAD. Please include Persistent Chat on ALL clients going forward. Also, please MODERNIZE it. It hasn't been improved in YEARS. So, even the clients that DO have it have a very mediocre PC experience. Our users have been asking for.
In most cases, users cannot eliminate the error due to the fact that the problem is not really in Skype, but in the browser Internet Explorer. Knowing this, we can eliminate the error as follows.
Solution 1
As a rule, it’s enough to delete the temporary files in Internet Explorer. Do it as follows: start Internet Explorer, click on the cog icon, select “Internet Options”, in the tab “General” click “Delete”, uncheck “Save the data of favorite web sites” and click “Delete”. Then restart Skype.Solution 2
If the first solution does not work, or you want to protect yourself from other problems with Skype, I recommend to reset all Internet Explorer settings and restart Skype.
Solution 3
Rather seldom a white screen in Skype can appear due to the fact that Internet Explorer cannot access the JavaScript library. If the first two methods don’t help, do the following:Skype For Business Blank Screen
- Download script register_js.bat
- Press right click on the file and select “Run as administrator”
- As a result, you will get three notifications on the successful execution of DLLRegisterServer
- Restart the computer
I would be grateful for any feedback and comments with details about which solution helped -->
Summary
After joining an active Lync conference the Lync conversation window does not contain any instant messages (IM).
Cause
The design of the Lync Instant Messaging Conferencing Unit (ImMcu) limits the amount of IM information that will be submitted to the Lync conference participants. The ImMcu message history component records each IM sent by the conference participants for the first 40 seconds after the first IM is added to an IM conference. Within the beginning 40 seconds the ImMcu message history component can manage a maximum limit of 50 IM at a time in its buffer. When the limit of 50 IM is met then the first IM for the conference will be removed from the ImMcu message history component as the last IM for the conference is added to the ImMcu message history component. After the ImMcu message history component's 40-second timer expires, the ImMcu message history component will clear all IMs from its buffer. These design features of the ImMcu message history component provide conference participants with the following experiences when joining a Lync IM conference:
- Participants that join the IM conference within the first 40 seconds of the IM conference will receive all of the IM that is current with the ImMcu message history component in their Lync conversation window
- Participants that join the IM conference after the first 40 seconds of the IM conference will not receive any IM and their Lync conversation window
Workaround
Mac Skype For Business Chat Window Blanket
To optimize the number of conference participants that will be able to view a Lync IM conversation window that includes the IMs that are buffered by the ImMcu message history component within its initial 40-second interval, use the following steps to sort the Lync contacts by availability:
- Select the Lync Display contacts by groups (Groups) feature of the Lync contact window
- From the View more layouts drop down list choose Sort by Availability
- Select the available contacts that will be conference participants from the sorted contact list.
These steps will help ensure that the IM conference invitations will primarily be sent to conference participants that will be available to respond to the IM conference invitations.
Note
IM conference invitations that are sent to non-responsive IM conference participants will hold for 15 seconds after receiving the toast notification for the IM conference invitation then they will join the conference by default.
