Issue: Unable to schedule Skype meeting on behalf
Error: The person you are scheduling on behalf of is not UC enabled or there may be configuration issues with the account. Make sure you are signed in to the same account you use for Microsoft Outlook.
When user “A” has calendar permission of User “B” to schedule meeting and it works for calendar meeting not for Skype online meeting. To schedule Skype on behalf of someone, owner must give permission on Outlook calendar and Skype for Business as delegate. E.g. Owner user “B” and User “B” delegate.
- Error message itself says that account on behalf of is not enabled for Skype for Business (UC).
- Both users who are schedule Skype for Business meeting and for on behalf of (e.g. User “A” and User “B”) should enable for Skype for Business.
- On User "B" Outlook delegate setting, the delegate must be listed to have correct delegate permission.
- Open Outlook (Outlook 2013/2015/2016) > click on File > Account settings> Delegate Access > Add > Find user name (to be as delegate) > click on Calendar Menu > Select Editor permission.
- User "B" machine Outlook must be running default profile that align the current sign-in Skype for Business account.
- Both User "A" and User "B" must be running Skype for Business full client. I think basic client does not support delegation.
- User "B" Skype for Business client delegation must be added
- Open Skype for Business > File > Tools > Option > Call Forwarding > Edit my delegate members > Add > then find user name "A" > Click OK complete task. Refer below image.
- You can schedule meeting using Outlook and OWA as well.
