Change display name on Calendar Invites

[KwmItAdmin]

I've combed through all the settings I can think to look through on this but my issue is thus:
When I send out Calendar invites or Task Requests, the name displayed does not match anything else I've set for my account. How can I fix this?

Hi @KwmItAdmin, I'd suggest double checking your display name and alias settings per these instructions: https://support.office.com/en-us/article/Change-a-user-name-and-email-address-in-Office-365-fb5ac074... Hopefully, you can see where that name is pulling from.  If you don't see it listed as the display name, please give our live support teams a call so we can find out more information and let you know how to proceed.  Thanks.

Thank you for your response, however I was unable to complete everything in the given link. Namely, I do not have an option for the User Name as described in the help article.

Any other suggestions would be highly appreciated.
