@Mary-Community_Moderator Thanks for the information.
It appears RingCentral(RC) is phasing away from the Deploy Add-In Link(see link below) and pushing users towards using the RingCentral Scheduler.https://support.ringcentral.com/de/de/article/11172-RingCentral-Meetings-Deploy-Outlook-Addin-User.html
The only thing I do not like about the RingCentral Scheduler is I'm unable to determine if I have scheduled a RC Meeting or an RC Video Meeting. Read through the instructions provided in the link below but it did not help. https://support.ringcentral.com/article/installing-ringcentral-scheduler-outlook-add-in-user.html
Anyway all this to say RingCentral has too many applications and hopefully they start consolidation apps to keep things simple.
