Displaying your screen content to others during a Teams meeting or call for collaboration
Based on the information you provided, I understand that when another participant shares their entire desktop in a Teams meeting, content such as Excel spreadsheets, Outlook, or web pages appears too small or unclear on your laptop. You would like to know whether you can zoom in on the shared screen yourself without asking the presenter to enlarge the content.
Please be advised that there is currently an active Microsoft Teams service incident, in which some users may experience degraded video quality during screen sharing. Microsoft has identified a recent meeting performance optimization update as the cause and is deploying a configuration update to mitigate the impact.
The issue is currently being investigated and monitored. I will continue to follow the service incident and will update you when further information becomes available.
I hope this helps.
