Re: Having an issue while importing Exchange OU
Login into Exchange ECP and then you can navigate to the menu : Mail Flow >> Accepted Domains, here you should select the accepted domain and click on Edit. Now make sure that Name and Accepted Domain fields are not different and should be same.
For example, if accepted domain is "domain.com" then its Name at this path should also "domain.com". After doing this modification, you will not get error while importing the Organization via HC10 panel.
