You cannot upload or share content during a conference call in Lync Online

To troubleshoot issue one

1. Verify that the PowerPoint presentation that you want to upload is not open anywhere else on the system.
2. Verify that the PowerPoint presentation is not protected by Information Rights Management (IRM).
3. Verify that there are no open dialog boxes in PowerPoint. For example, such as when you click File, and then click Open.
4. Verify that PowerPoint is installed on the computer on which you are trying to upload the slide deck. Also, verify that PowerPoint is not set to install on demand.
5. If the PowerPoint presentation still cannot be uploaded, collect Lync troubleshooting data by using the Microsoft Online Services Diagnostics and Logging (MOSDAL) support toolkit 3.0, and then escalate the issue to Office 365 Technical Support.

To troubleshoot issue two

1. Verify that the file size of the content that you want to upload is not too large. PowerPoint presentations, Microsoft Word documents, multimedia, or snapshot slides are all converted during presentation, which expands/contracts the size of the original file.
2. Determine whether the Online Meeting quota was exceeded. By default, the meeting quota is set to 500 MB.
3. Determine whether more than the maximum number of files was uploaded to the Online Meeting. The total size of all files in a conference must not exceed 500 MB. Open the content bin and/or handouts to remove other files if the quota is exceeded.
4. Verify that the format of the file that you want to upload is in a format that can be uploaded. For more information about files that can be uploaded, see the following Microsoft webpage:
   Why Are My Users Unable to Use Communicator 2007 R2 to Transfer Files? (http://technet.microsoft.com/en-us/library/ff394137.aspx)
5. Determine whether ports 443 or ports 50000-59999 are blocked by the Windows Internet Explorer HTTP proxy. 
6. If you still cannot upload a document, collect Lync troubleshooting data by using MOSDAL 3.0, and then escalate the issue to Office 365 Technical Support.

To troubleshoot issue three

1. If a static image is not displayed correctly, try to reproduce the issue by using the same .ppt file that contains the image. Then, try to reproduce the issue by using a different .ppt that contains the same image.
2. Note that some content (video, multimedia) will be removed from the deck during the upload process.
3. Collect Lync troubleshooting data by using MOSDAL 3.0, and then escalate the issue to Office 365 Technical Support.

To troubleshoot issue four

1. Verify that you have the correct certificates in Certificate Manager. To do this, follow these steps:
   1. Open Certificate Manager. To do this, click Start, click Run, type certmgr.msc, and then click OK.
   2. Expand Personal, and then expand Certificates.
   3. Click the heading for the Issued By column to sort the column, and then look for a certificate that is issued by Communications Server.
   4. Verify that the certificate is present and is not expired.
   5. If the certificate is expired, right-click the certificate, point to All Tasks, and then click Renew certificate with New Key.
   6. Try to sign in to Lync Online. If you cannot sign in to Lync Online, delete the certificate, and then try to sign in to Lync Online to download a new certificate.
2. Verify that you have the appropriate permissions to save to your target destination.
   • Verify that the user has permissions to save content. Have a presenter open the content bin (or attachments if the file is an attachment), click the right arrow (or right-click) and click Make Available to. Make sure this is set to the role of the person trying to save the file.
3. If you save to a network location, verify that you have Read/Write permissions to the network share.
4. If you cannot save content in the XPS format only, check the XPS print queue. To do this, click Start, click Devices and Printers, open the Microsoft XPS Document Writer, and then delete all pending jobs that seem to be stuck.
