wish that help

the ECP is limited on what it can do.  The one feature that ECP can not control is giving access rights to a mailbox which needs to be done in the EMS.

use exchange remote powershell its same of EMC and will help you in command lines

Run this cmdlet:-
 

[PS] C:\>Get-Mailbox -Identity akicute55@xyz.com | Add-MailboxPermission -User "Admin@xyz.com" -AccessRights FullAccess

Select allOpen in new window

Hope it will be helpful for you....

@TheGeeksCentralCA would like to tell you that the cmdlet provided by @jordannet will also work for you. To use that you have to provide mailbox unique Identity as UPN. This is because in multi tenant hosting environment exchange can have two users with same name but UPN name can't be the same ever. So when ever you want to apply any settings on users in multi-tenant  environment you have to privide the unique Identity of users.

Hope this will also be helpful for you...
Good Luck

nope, didnt work. I get a Unexpected token 'C:\>Get-Mailbox' in expression or statement

For multi-tenant you will need to add an additional marker to ID a mailbox.

should be: Get-Mailbox -Organization <<put org name here>> -id xxxxx ....

Nope.. still doesnt work. I get the same error.  "Unexpected Token"

this is what i am typing in just so you guys see that i am typing it in correctly.

Get-Mailbox -Organization "org name" -Identity name@domain.com | Add-MailboxPermission -User "name@domain.com" -AccessRights FullAccess

Replacing the org name and email addressess with the appropriate as needed.

OK, how many CAS and HUB servers?
Could be possible you have too many CLI sessions open and not loading all the commands.
I have seen some weird behavior with Hosted mode clusters and this was one of them.
I would close check all servers and make sure there are no active sessions and close all of them out, then close CLI and re-open.

please read here .. its explain more :

Please share the error screenshot. So that we can analyze where the issue is exactly.

here is the screenshot.

 

Nope didnt work. here is the results.
 

it looks like the logged on user does not have permission...

i do have permission. i am the only admin on this box. i have god rights. i can do anything and everything else.

We do understand that you are the top level admin but when we create new organization in hosted  environment it create it own permission group or administrator. So please add your admin once in the ou administrators group. and then try.

This worked! Thank you to akicute555 for your help!  For the dumbest reason, i failed to see the part of logginging in as the administrator of that hosted domain to run the command.  I figured that the main admin account which i was logging in as had all the rights since i was able to setup and install exchange hosted setup with that user and run any other commands, that it would be fine.

Comes to show, to give rights you have to be logged under the correct admin for that domain.

i must have a point at least i leaded you from the beginning how to use Powershell when you are no longer able to administrate and manage your Exchange..
anyway thank you and good luck
