Announcing Deprecation of Remote PowerShell (RPS) Protocol in Exchange Online PowerShell
Even though we use Disconnect-ExchangeOnline whenever we open a connection using Connect-ExchangeOnline, sometimes we see some folders(tmpEXO*) in C:\Windows\Temp. Some folders contain an internal folder en-us which is mostly empty.
But some en-us folders contain xml help files like : Microsoft.Exchange.Management-Help, Microsoft.Exchange.RemoteConnections-Help, Microsoft.Exchange.TransportMailflow-Help etc. This is a problem for us as our application is a multithreaded daemon continuously opening connections with exchangeonline and closing them which is leading to high disk space usage.
Note: Earlier when we were not using Disconnect-ExchangeOnline, we were still seeing those temp folders(a lot more actually) and those folders contain some powershell scripts apart from the help files. So it looks like sometimes clean up is not happening as expected and help files are not getting deleted.
