I have an issue, I have done this before and it worked fine:
I created a 365 user account, and shared a calendar, then created a group and gave that group read/write (author) access to it.
but ever since exchange/365 upgraded its self to exchange 2013, I keep getting an error when trying to do the same sort of thing with a user, I have created the calendar, and for some reason when I try do the command to change permissions for it, I get the following error:
"The operation couldn't be performed because 'oc@company.com.au:\HR Leave' couldn't be found."
obviously I changed the company name from its real one, but that's after I did the following command:
Add-MailboxFolderPermission -Identity "oc@company.com.au:\HR Leave" -AccessRights Owner -User doug@company.com.au
I thought maybe it was because the calendar I created has a space in the name, so I changed it to just HR, but that too didn't work... what's going on?!?
Is Microsoft just being spastic today or am I doing something wrong... I even tried that with just the username without the @domain name instead, didn't work, same error...
I really would appreciate any help you can give me in relation to this matter.
