Hello everyone I am looking for tip on how to do this process easier and more effective ?We have 3 domain names hosted on exchange ?There are 7 users that have accounts from all 3 domains ?There is one primary account and the incoming mails to other accounts get forwarded to primary ?Users reply to different domains but use the option from and answer from proper domain ?Now we want to give pretty much full control to all these 7 people to each other box, including read, write, send as ?It is a crazy and messy process if I want to go on every mail box and set up permission for other 6 users * 3 domains, so I tried to make a group and put all these guys into that group and set permissions. But it actually made the situation worse and none could send email to each other coming back as permission denied ?So is there any easy process or third party or trick which makes this task easy for me? Instead of doing 21 account * 20 others which is 420!!! Help is apperciated
