I know somebody here will say that this is a duplicate of some thread but, I dont get a clear answers from those thread and also not found anything that works as of this writing.
We just encounterred the 401 unauthorized on our API that uses Microsoft.Exchange.WebServices.Data's codes for sending automated emails that was working before
I checked the shared mailbox we used if its credential thats causing the issue however, it seems to not be the issue as its still valid
Are there any changes or updates done relating to this?
Are there any new approach to make it work again?
