I have done a recent migration to Office 365 from Exchange 2003. Several users had read/wite access on other users Calendar and Inbox send permissions to send emails from their accounts from their own Outlook accounts.
I don't understand this Powershell and how to connect to my online Exchange server on the cloud.
I need to allow these users to have read/write access on these calendar's. Sharing them ONLY gives read access regardless if you share it, or publish it.
I need some good guidance on how to use the Powershell or a GUI that will allow me to accomplish what I need to do, give read and write access to the calendars, and the inboxes.
Users are able to use Outlook 2007 with SP3, or the web portal to access their accounts currently.
Thank you so much.
