Speicherblock Hosted Exchange customer

Customer with Email services hosted by another provider

If your Exchange services are hosted by another provider, please follow the steps below to create your Mailstore users.

In the Mailstore Client, click on Administrative Tools > Users and Archives > Users menu. Then click Create New…


Give the login name of the user. It’s practical to give this user the same username as the Exchange user, because like this the user has to remember only one login name.


Specify the Password and the Privileges of the user:


If you give the Change Password privilege to the user, when they log on to the Client with their current password, they will be able to click the Password… button (marked as 1 above). If this access right is not present, the button is grayed out.

Forgotten password

If a user forgot their password, the administrator can specify a new one.



If the administrator forgot their password, please get in contact with the provider.

Archiving Profile

What is an Archive Profile?

Archiving profiles contain the settings of which user to archive, what to archive and what to delete after archiving. This profile is to preserve the folder structure of the mailbox, so if we have to restore something, the folders are kept as well. To meet legal requirements of keeping each and every email of a mailbox, we’ll use the Journaling function.

We advise you to create one profile for the whole company, which will be run once a day. Please, do not create archiving profiles for each user.

To archive all mailboxes of your company, you need to have a user with the Application Impersonation access right set. This enables the given user to access the mailboxes of all other users of your company but only through the secure protocol EWS.

If you wish to archive O365 mailboxes, please, click here.

Application Impersonation

If you use the Hosted Exchange of Speicherblock, follow the steps below to set this up. If your Exchange services are hosted elsewhere, please ask your Exchange provider to set this up for you.

To enable this access right in the Speicherblock Hosted Exchange:
