Hi @Max Mayorov
I wasn't able to reproduce error. Per our offline discussion, you are no longer seeing this issue.
More than likely, it was an issue with the connector resolving the Outlook API that has since been resolved. I've reached out to the product group for any additional insights. Should I come across any, I'll be sure to update this post.
UPDATE 5 December 2024
The tenant id utilized by the Power Platform connectors was inadvertently removed from the V2 allow list, which resulted in the error message. There is migration path towards MS Graph instead of the V2 API which led to accidental removal. This issue has been mitigated and apologies for the inconvenience.
