Greetings all and thanks in advance,

I know this question has been asked up and down, sideways and back, but I cannot find the solution for me.

Migrated mailboxes from Exchange 2007 to 2013 on-prem.  Outlook 2013 client.

I used to be able to open the properties of any and all shared or regular user's calendars.   Now, when I open a shared calendar, I can see the calendar contents, when I right-click on the calendar to select properties.....to set or review permissions, I get the following message: 

Cannot display the folder properties. The folder may have been deleted or the server where the folder is stored may be unavailable.  Cannot display folder properties. You don't have appropriate permissions to perform this operation.

When I look at the permissions on the calendar from the cmdlet, Get-MailboxFolderPermission -Identity cfvioletcrown:\calendar |fl  I see all the permissions I have set on the calendar in the past. I would not expect to see my name listed here.

I then look at my permissions on the whole mailbox:

Get-Mailbox crbrazos | Get-MailboxPermission -User UserAccount

Identity             User                 AccessRights
--------             ----                 ------------
HALFF.AD/Resource... HALFF\UserAccount         {FullAccess, ReadPermission}

I have Full Access. 

As the email admin and a domain admin, I'm expected to have access to everything.

How can I resolve?

Thank you,

Willis

Found the solution.  Hope this helps someone else.  Thanks Paul Cunningham.

How to Grant Full Mailbox Access for a User in Exchange Server 2013

 

• Identity the mailbox you are adding the permissions to
• User the user you are granting the permissions to
• AccessRights the level of access you are granting

 

    Add-MailboxPermission -Identity Alan.Reid -User Sarah.Jones -AccessRights FullAcces

To prevent auto-mapping we need to add -AutoMapping:$false  (automagically linking to calendar)

    Add-MailboxPermission -Identity Alan.Reid -User Sarah.Jones -AccessRights FullAccess -AutoMapping:$fals
