MAPI Permissions
The MAPI permission requirements for Exchange Server 2007 are:
| • | Administer information store |
To assign the service account the required permissions at the Exchange Server level, follow these steps depending on how your Exchange environment is configured.
If inheritance to the individual stores is enabled, to set the required permissions at the server level, follow these steps:
| 1. | Open the Exchange Management Shell and connect to Exchange Server.
|
| 2. | Type the following line, and then press ENTER:
Get-MailboxServer <Exchange2007> | Add-ADPermission -User <Account> -AccessRights GenericRead, GenericWrite -ExtendedRights ms-Exch-Store-Admin
where <Exchange2007> is the name of the Microsoft Exchange Server server and <Account> is the name of the account to which the permissions will be assigned. If <Exchange2007> is omitted, the right will be assigned to all servers in your organisation. |
If inheritance to the individual stores is not enabled, to set the required permissions at the store level, follow these steps:
| 1. | Open the Exchange Management Shell and connect to Exchange Server.
|
| 2. | Type the following line, and then press ENTER:
Get-MailboxDatabase <MailboxDatabase> | Add-ADPermission -User <Account> -AccessRights GenericRead, GenericWrite -ExtendedRights ms-Exch-Store-Admin
where <MailboxDatabase> is the name of the mailbox database and <Account> is the name of the account to which the permissions will be assigned. If <MailboxDatabase> is omitted, the rights will be assigned to all databases in your organisation.
|
Important When a new mailbox database is created, step 2 must be repeated.
