The following is a list of frequently asked questions (FAQs) about RingCentral Scheduler.

General questions

I scheduled a meeting with RingCentral Scheduler, so why is there also a Microsoft Teams meeting in my Outlook invitation?

MS Outlook invite while using RingCentral Scheduler
Microsoft automatically adds a Teams meeting to every new Outlook Calendar invitation.
If you’ve used a Microsoft Outlook add-in, such as RingCentral Scheduler, to add a meeting invitation, you’ll see the RingCentral meeting details in the invitation.
You can turn this feature off manually in your Outlook Web Settings. Your company’s Microsoft admin can turn this feature off globally from the Microsoft admin center.

Why is the RingCentral Scheduler add-in grayed out or missing from my Outlook invitation?

When you upgrade Microsoft Outlook, some add-ins might not display correctly, or may be missing from the Outlook user interface.

To have your add-ins reappear, you can switch back to the old interface, then switch again to the newer user interface. You can also simply restart Outlook.
Read more about displaying Outlook add-ins from  Microsoft Documentation and Stack Overflow.

Why does my “Schedule on Behalf” feature not work in Microsoft Outlook?

Check the version of your Microsoft Outlook client. The “Schedule on Behalf” feature only works with Outlook 2016 and later.

Which RingCentral plug-ins or add-ins are available?

  • Plug-ins are installable file packages that can be used only from the Outlook desktop app. Plug-ins make changes directly to the user registry, which means they are somewhat vulnerable.
  • Add-ins add software functionality and can be installed across platforms (web, desktop, and/or mobile) from the Microsoft App source. Add-ins, which are cloud-based, conform to strict web security and privacy mandates.
We recommend that all customers install the Unified RingCentral Scheduler add-in, which is actively maintained by RingCentral and provides the latest scheduling and security features.

When I add a meeting with RingCentral Scheduler, why do the meeting details appear at the end of the invitation?

RingCentral Scheduler adds meeting details at the end of invitation emails so those details do not disrupt any custom content.

How do I get RingCentral Scheduler to appear in the More menu of the Outlook invitation?

Does the RingCentral Scheduler add-in work on VMware VDI?

Yes. RingCentral Scheduler works with Horizon VMware and Citrix VDI. Contact RingCentral support if you’re having problems running the Scheduler add-in on your virtual machines.

I already logged in to the RingCentral MVP unified app. Why do I need to log in to RingCentral Scheduler again?

RingCentral Scheduler uses the Microsoft Outlook Add-in framework and resides in a different domain than the RingCentral MVP app. Although it’s not possible to share credentials between these applications, you can use your Single Sign-On (SSO) account to log in to RingCentral Scheduler once you’ve allowed Scheduler to display a login window.

How does Microsoft’s retirement of Internet Explorer 11 affect the RingCentral add-in?

Microsoft stopped supporting Internet Explorer 11 (IE 11) on June 15, 2022. If you installed the RingCentral Scheduler add-in with IE 11 and run the add-in on Windows, you may experience problems with the add-in in Outlook.

If you’re using software on the “retiring” list, we recommend either of the following:
  • Upgrade to another Outlook version (depending on which version of Windows you’re using).
  • Switch to an application that best fits your needs such as the RingCentral for Outlook plugin or switch to  Outlook on a web browser.
