I received this error when sending from a shared mailbox: "Failed to retrieve token for resource=https://outlook.office365.com. Message=An internal error occurred." The interesting thing is that this error only occurred on 1 out of 75 runs. I had another flow setup that was creating list items and that was triggering the send from shared mailbox. Any help with this would be appreciated. I would like to use flow more often but it seems like I have the random errors more often than not and have no idea why there are issues.

Hi @cdmcali,

It might be an internal server issue, temporarily. You could click the failed run, then click the top-right resubmit button to let it run again:
