Occasionally an error occurs in Disconnect-ExchangeOnline
TL;DR - Add Start-Sleep 60 to your script right before your Disconnect-ExchangeOnline command. Adjust the Sleep length down if needed/preferred. 15 seconds works fine for me.
A couple things. First, the ExchangeOnlineManagement module Microsoft page says that it is built to function on all PowerShell versions 5.1 and above.

Second, I am getting this as well, and am getting it pretty consistently right after upgrading the ExchangeOnlineManagement module on a Scheduled Task server to v3.1.0. I assume it's a bug and will get ironed out eventually. However, I keep getting alerts because one of my scripts is throwing this error.
Based on Varun's suggestion above, I manually deleted the temp folder that was identified in the error as "unable to be deleted". I was able to manually do this in the file system every time without fail. So I'm thinking it's the PowerShell process itself that needs a little more time hanging on to the files in the temp folder before they can be deleted.
Not proud of it, but adding a Start-Sleep 15 just before the Disconnect-ExchangeOnline -Confirm:$False line is now preventing this error from occurring on all subsequent runs. Until MS figures it out, this seems like a solid temporary fix. Of note, of the many Exchange scripts running on this server, this script is the shortest, lasting a minute or less. It's possible a certain amount of time needs to pass between connect and disconnect or the files in the temp folder aren't completely downloaded (or something...)
