Exchange activity: send mail error: No mailbox with such guid


By using SendExchangeMail activity to send mail, am keep on getting an error “No mailbox with such guide”

Can anyone help me sort out this error.

Hi @Prasaanth_S1 ,

This error usually occurs when the Exchange server is unable to find the user whose mailbox you are trying to access.

Make sure the user exists in your Exchange server, and check the spelling of the username you are using to access the mailbox. It should also make sure that you have the correct permissions to access the mailbox.

Hi @RajKumar_DC ,

I checked the server, username, password all the things, from last week this issue was raised, and it was working fine untill then
