Many organizations use software that needs access to users’ mailboxes. In this case, it makes sense to assign the necessary permissions centrally. Exchange provides the impersonation role for this, which can act on behalf of the respective users.

Many companies today have branches in several countries or an international workforce. In this case, they generally use English as the corporate language. However, Microsoft Teams offers the option of automatically sending invitations to meetings in a second (local) language.

Exchange administrators should know the maximum possible mailbox size in the environment they are managing, whether on-prem or in the cloud. In an on-prem installation, admins can use this information to prevent excessive database growth. In the cloud, excessive mailbox sizes might require an upgrade of the M365 plan. The configuration of the mailbox quota is possible both in the Exchange admin center (EAC) and via Exchange PowerShell.

The OneDrive client synchronizes files between the local computer and the cloud. Sometimes, it can happen that this synchronization does not work properly. You then have a different file status on the PC than in OneDrive. Resetting the OneDrive client usually solves this problem.

CU22 and CU11 for Exchange 2016 and 2019 install the new Emergency Mitigation (EM) function. It is intended to implement immediate measures automatically when critical vulnerabilities occur. These can reduce the threat but can also deactivate Exchange features.

A new feature in Windows Server 2022 is support for Quick UDP Internet Connections (QUIC). This protocol, which is based on UDP, can be used for DNS or SMB traffic. In Server 2022 and Windows 10/11, it accelerates access to file shares via the Internet and can replace VPNs.

The automatic or out-of-office “OOF” reply (also called “out-of-office assistant”) has been available in Exchange for a long time and is one of the most important features for end users. If they can’t set up their automatic replies themselves, the admin can use ECP and PowerShell to do so.

If organizations do not want to transfer their password hashes to the cloud in a hybrid AD configuration, they can use ADFS for authentication. A compromise with less overhead would be to sync the passwords only of selected users with AAD Connect.

You may have noticed once in a while that calendar entries in Exchange are defective in some mailboxes, but Exchange isn’t able to repair them with onboard tools. Although you can’t fix the problem online, you can use tools for offline repair.

Encrypting drives with BitLocker is essential for protecting Windows notebooks against theft and misuse of data. However, if users lock themselves out, the only thing that would help them is a recovery key. Admins can store this key in the Active Directory and retrieve it as needed.

Exporting mailbox items to a .pst file is the ideal way to migrate mailboxes or to perform an ad hoc backup. When Exchange is used in the customer’s datacenter, PowerShell can handle this task. In Office 365, however, the GUI from eDiscovery is provided for this, but it makes this process relatively complicated.

With Office 365, Microsoft offers services such as Exchange, SharePoint or Office Web Apps (OWA) as well as Office subscriptions. If companies want to avoid the hassle of installing and maintaining Exchange, they can use the cloud version. This guide describes the basic configuration of Exchange in Office 365.

Before you can manage mobile devices with Intune, you need to enroll them with Microsoft’s cloud-based mobile device management (MDM) service. In addition to Android and Windows 10, it also supports iPhones and iPads. First you have to apply for a certificate from Apple, and then you can download the required Intune app onto the device.

Microsoft Intune is a cloud-based client management solution that manages PCs and mobile devices. This article shows you how to register the tool for a free 30-day trial and set up users via the Office portal. Device management then takes place through the Azure portal.

SSL connections are now standard for publicly available websites, and the same should apply to Microsoft Exchange. Let’s Encrypt operates a free certificate authority (CA) that not only issues certificates free of charge but also allows automating the renewal requests. This guide goes through the procedure for IIS and Exchange.
