The LDAP address book (LDAP = Lightweight Directory Access Protocol) is a type of database or directory that an email application queries via a predefined path (server name, port, branch/search base) in order to find out the user certificate of an email address, for example. If such an LDAP address book is integrated into your own email application, encrypted emails can be sent directly, for example, provided the recipients have published their user certificate in the LDAP address book. Not every e-mail has to be sent encrypted, but you can select this option if you wish and after successful setup. Read more about the encryption of emails in part 2 of the blog series.

Go back to the first blog post in our series to read more about digital signatures.

This gives students (and employees) the necessary rights to use the software.
Due to new votes and licence changes on the part of Microsoft, the storage space for OneDrive and SharePoint Online on the tenant for students has been redefined.
