Microsoft Remote Connectivity Analyzer (MRCA) is a self-help tool to test connectivity issues with exchange or email services for any email account or shared mailbox. IT Admins can use this tool to test the mail flow configuration of any newly setup email account or problems with any existing email account.
Tests included in this tool are also intended for those customers who use the
Exchange Online Protection service to perform spam and malware filtering before sending email messages to email servers.
IT Admins can send this web-based tool link to end users so that end users can perform some defined tests themselves and send results back to IT Admins.
For examples, a simple test for checking if the mail flow configuration (for any email account or shared mailbox) is working or not is to just try sending email to that email account.
