Your message wasn't delivered because the recipient's email provider rejected it. - Calendar in Team

[jvillarroel]

Hi All,

I've been experimenting a weird behavior when creating appointments from the MS Teams Calendar.

I just created the Tenant (Office 365 E1 Trial - COVID19 Eval) and when creating appointments through MS Teams Calendar, the email is not delivered to the people I'm inviting (inside and outside of my organization).

Is it something I have to configure in the Admin page?

Any tip of advice will be very well received! Thanks in advance.

Regards,

Had the same error the last weekend on a fresh EDU tenant.
The workaround was to schedule the teams meeting via outlook. This worked for us.
Need to double check if this issue still exists.

Our EDU customer has a same behavior.
