Going through my archives of KBs I had previously documented, I came across this error. While there could be many possible issues this could be occurring at a client level, the fix in my case came from server side.
The Issue - Error observed in Outlook while creating an SFB meeting
"Create Skype Meeting Failed. Please make sure that Skype for Business is running and signed-in and try again".
Scenario
15 HRs (Delegates) have access to shared mailbox, Careers and are unable to create meetings in Careers calendar in Outlook.
Troubleshooting & Fix
· Checked from SefaUtil. Everything was okay. The error wasn't about permission issue.
· Checked from Exchange/Outlook perspective. Delegation was setup correctly.
The error although mentions, Skype for Business is not running in background, it actually is. And logs will later reveal the pop up (error) is not related to that but due to a threshold.
Collected Skype Client logs. Analyzed in Snooper (tool to parse Skype for Business SIP transactions).
You’ll notice a SERVICE method OUT and an error coming IN towards SFB Client.
Let’s look at both:
This parameter is under “UserServicesConfiguration”.
-MaxScheduledMeetingsPerOrganizer >> By default it is set to 1000 (Global)
Running Get-UserServicesConfiguration, we can verify this in the default (Global) UserServicesConfiguration. Now, either we can modify the Global policy or for testing purposes create a new one. UserServicesConfiguration can be created as per Site level or Pool level. (We can’t map it to a user identity)
Since Careers account is hosted in SFB-FE-Pool 3, created a new UserServicesConfiguration in the same Pool only.
New-CsUserServicesConfiguration -Identity service:UserServer:sfbeepool3.domain.com -MaxContacts 250 -MaintenanceTimeOfDay "1:00 AM" -MaxScheduledMeetingsPerOrganizer 2000
Bumped the value to 2000
Tested with delegated user (Ross) and found issue to be resolved. He was able to schedule a meeting on behalf of shared mailbox: Careers.
This also proved, pool level configuration took precedence over Global level.

Conclusion
If you've a shared mailbox like Careers (for HRs to setup interviews) or Sales / Finance which many employees could be using to schedule meetings on a daily basis as part of delegation, then you might face this issue. Consult with your Skype for Business Administrator as the threshold set by the organization might have been reached. Best to stretch this limit to a bigger number part of capacity planning.
