EWS Auth failes since Thursday with MaxConcurrency
Hi Milan,
Since yesterday EWS Authentication failes on my machine (Ubuntu 20LTS). It says 'Failed to connect' and 'Unknown error'.
I didn't make any changes beside daily Ubuntu updates, and Azure is still setup as before, also password hasn't changed.
I also cannot create a new account - it fails on the 'Fetch URL' step with the authentication providing no feedback, just asking again for the password. However, using the 'Fetch URL' button in the existing account, works and receives OAB URL. Strange...
When debugging I get the following response - does this make any sense to you?
<s:Fault>
<faultcode xmlns:a="http://schemas.microsoft.com/exchange/services/2006/types">a:ErrorServerBusy</faultcode>
<faultstring xml:lang="en-US">The server cannot service this request right now. Try again later.</faultstring>

Thanks a lot!
