Syncing Yahoo calendar (already added to Outlook) to MS Teams calendar

Dear ER_2017

Thank you for your reply.

Yes, it is indeed because Teams is not logged in, because Yahoo is not a Microsoft account, which leads to the inability to log in. You can register it as an account or add the Yahoo mailbox as an alias of the Hotmail account to try to see if the Yahoo mailbox can be displayed.

Hmmmm...sorry, I am back. Here are a few pics to explain my situation better.
Pics 1 and 2 will show that my Yahoo is already signed into the Outlook. As is my hotmail. The calendars of Yahoo and Hotmail show up.

PROBLEM: But on MS Teams, the Yahoo calendar does not show up (despite being on my Outlook. I thought Outlook and Teams would sync when I have signed in on my primary account (my hotmail.). And I cannot add the Yahoo account on Teams because it is only asking for an Office account. Is this the reason why Yahoo calendar entries on Outlook do not show on Teams? Thank for your patience.

is the reason why my Yahoo calendar doesn't show up on Teams.

Dear ER_2017

Thank you for your reply.

So you are logged into Hotmail in your Teams, right?

If you are not logged into a Yahoo mailbox, you will indeed not be able to synchronize the Yahoo calendar in Outlook.

I think you can try to use Yahoo email as the account alias of Hotmail email to try to synchronize the calendar. You can refer to this link:

Hi there. On Outlook, I have my hotmail and yahoo accounts added. When I accept invites to a Teams meeting sent to either one, I see it on the Outlook calendar.

On Teams though, I see only the accepted meetings sent to my hotmail. Those sent to my Yahoo even when accepted do not show up on the Teams calendar. So in this case, the Outlook calendar does not fully sync w/ Teams calendar. Is it because I cannot add/sign in on Teams a Yahoo account? Or is there a way?

Thank you.

Dear ER_2017

Thanks for raising your concerns in Microsoft Community.

We understand that you are inquiring about calendar synchronization in Teams. We need to check with you if the account you are logged in to in Teams is the same as the Yahoo Mail account.

Because the calendar in Teams synchronizes with the calendar of the mailbox associated with the account you are logged in to, if you are logged in to other mailboxes in Teams, it will not be synchronized. But if you are logged in this Yahoo mailbox, the calendar in Teams will synchronize with the Yahoo calendar in outlook.

I hope the above information is helpful to you. If you need further help, please feel free to reply.
