An unexpected error occurred on a send about pswindocumentation.o365healthservice

I've moved this to a proper repository. Just tested on 7.0, 5.1, and 6.2.3 and it seems to work fine here.

But to be honest I've got a similar report few days ago over the email

Which looks exactly like yours.

Maybe this:

If you have gotten the "Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send." error while using PowerShell then add the line below to your script.

​[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

PowerShell calls uses TLS 1.0 for web requests by default. However, Exchange is expecting a higher level of TLS, so you need to tell PowerShell to use 1.2 instead of the default of TLS 1.0.

Have you enforced TLS 1.2 recently? Can you verify this?

Perfect !!!
I Add

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

and now it's ok !

[PrzemyslawKlys]

Ok, I'll add it to the code and publish a new version. Sorry for the inconvenience.

[br-rafael-martins]

There was no inconvenience ;). I appreciate your excellent work in making this module.

[PrzemyslawKlys]

Please test the new version. Update-Module ... and then restart PS and let me know. Thank you!
