Hello,

I have been invited to a Lync Online Meeting by a contact from an external company.
On our side we use Lync as part of our Office 365 subscription.

I am able to join the conference but it seems I can't share my screen to make a presentation.

Is there anything to set to allow screen sharing?
Is screen sharing supported for conference with participants from different organizations?

Thank you!

Hi,

You have to be a presenter in the meeting to share your desktop or presentation. You are only a attendee by default.

Hi Charles,

Holger is right, you do not have the right permission.

You have to ask the conference organizer to make you as a presenter.

( Check this article: https://support.office.microsoft.com/en-us/article/Set-options-for-Lync-Meetings-f628a0fe-6b94-469b-975c-8852a19bddad?CorrelationId=1a280a4f-efd5-4c9e-b2e5-dc3313221a12&ui=en-US&rs=en-US&ad=US

When you select People I choose, click Choose Presenters and move the participants from Attendee to Presenters side. External invitees and distribution lists cant be added as presenters with this option, but you can give presenter permission to individuals when you are in the meeting.  )

Best regards,

Eric
