I am using send mail message activity, but from last few days it’s not working and gives an error :
Send Exchange Mail Message: The request failed. The remote server returned an error: (403) Forbidden.
What is the cause of this error? How can we solve it?
The error message is produced when there is a problem connecting to the source/target server. Make sure you provided the right name or IP address of the server and the right EWS server address.
ensure that we have mentioned this in server property
https://outlook.office365.com/EWS/Exchange.asmx
Cheers @manzar_ali
In server property of the activity, Companies mail host is defined
Hi
if your company outlook mailbox is been configured from exchange mail activity then this will be the server buddy
https://outlook.office365.com/EWS/Exchange.asmx
Cheers @manzar_ali
I changed the server property, It gives 401 unauthorized error
kindly check whether the credentails are mentioned correctly
@manzar_ali
They are not changed, This activity was working since last week with the server property set as company mail host.
fine
can i have a view on the property panel of SEND EXCHANGE MAIL ACTIVITY with a screenshot if possible
would like to validate once the property values
@manzar_ali
let the exchangeversion property be 
and exchange with server as (if its a outlook)
https://outlook.office365.com/EWS/Exchange.asmx
or
we can check these details in your mail settings with server value in it…mention the same
I made the changes you suggested, it states 401 unauthorized error
buddy Error 401 usually means that your username or password is wrong. i hope Eventually you don’t have proper rights to access this server or your system is blocking to access it because of any firewall of antivirus…kindly check that pls
or
check with your server settings in mail application for exchange may be like this
Username and Password is same, I confirmed it, and it was working with Company mail host set in server property and Exchange Version as Exchange 2013 upto last week and no antivrus is installed from last month I checked, Where can the problem lie?
It gives 403 Forbidden error, when I change the server property as you suggest then it gives 401 unauthorized error
I am fencing the same Issue
Send Exchange Mail Message: The request failed. The remote server returned an error: (401) Unauthorized.
I used Server: “https://outlook.office365.com/EWS/Exchange.asmx”
UserId & Password is correct

Hello All,
I was facing the same issue and after trying all the possible workaround I resolved it by changing property AuthenticationType > Interactive.
Hope this helps.
