However, it is important to note that the security of Hosted Exchange® also depends on other factors, such as configuration by the customer, management of user access, and the strength of the passwords used. It is the responsibility of the organization to implement security best practices to further strengthen the security of Hosted Exchange®.

In general, Hosted Exchange® provides an extremely robust security infrastructure and offers organizations a highly secure environment for managing their email and communications.

Not directly. Outlook® is an email client and personal information management software developed by Microsoft®. It can be used to access email, calendar, contacts, and other features managed with Exchange® services.

If you have an Exchange® account, you can use Outlook® to access your account and manage your email, appointments, contacts, and tasks. Outlook® provides a user-friendly interface that allows you to efficiently use your Exchange® account and take advantage of Exchange® features and benefits.

However, it is important to note that Outlook® is not exclusive to Exchange® accounts. It can also be compatible with other email services such as Gmail®, Yahoo Mail® and others, although some features may be limited if not associated with an Exchange® account.

Overall, Outlook® provides a powerful and versatile platform for managing email and other information, and it can be seamlessly integrated with an Exchange® account to provide comprehensive features and integrations.

With Exchange®, your email resides on a server called the Microsoft Exchange® Server. The Exchange® Server stores the email and other information associated with your Exchange® account in a centralized database. This database can be hosted either locally in your own organization or in the cloud, depending on the deployment method you choose.

In an on-premises deployment, the Exchange® server is hosted in your own data center or on your own servers. Email is stored on the Exchange® servers, which are managed and maintained by your organization.

With a cloud-based deployment, such as Hosted Microsoft Exchange®, your emails are stored on our servers in a German data center. Our cloud servers offer scalability, reliability and a wide range of features for your Exchange® account.

Regardless of the delivery method, access to your email is available from a variety of devices, including desktop computers, laptops, smartphones, and tablets. When you log in to your Exchange® account using an email client such as Outlook®, a web browser, or a mobile app, your email and other information is retrieved from the Exchange® server and displayed.

It’s important to note that Exchange® is a comprehensive email, calendar, and collaboration solution. Therefore, not only your emails, but also your calendars, contacts, and other information are stored and synchronized in the Exchange® Server for seamless use across different devices

There are several apps that can be used to access Exchange® mail. Here are some popular options:

  • Microsoft Outlook®: Microsoft Outlook® is a comprehensive email and information management app designed specifically for accessing Exchange® accounts. It offers powerful email, calendar, contacts, and tasks features. Outlook® is available on multiple platforms, including Windows®, macOS®, iOS®, and Android®.
  • Microsoft Exchange® Mobile Apps: Microsoft® offers dedicated Exchange® Mobile Apps for iOS® and Android®. These apps provide access to email, calendar, and contacts from your Exchange account. They offer a user-friendly interface and integration with other Microsoft® services.
  • Apple Mail®: If you use an Apple® device, such as an iPhone® or iPad®, you can use the default Apple® Mail app to access your Exchange® mail. The Apple® Mail app supports Exchange® accounts and provides basic email functionality.
  • Android® email app: Android® devices have a built-in email app that provides access to Exchange® accounts. This app may vary by device manufacturer, but typically provides basic email functionality and support for Exchange® accounts.

There are other third-party apps from various developers that provide access to Exchange® mail. Before selecting an app, check its ratings, features, and compatibility with your device and operating system to make sure it meets your needs.

Ultimately, the best app for Exchange® mail depends on your individual preferences, your device, and the specific features you need.

Please note that the exact steps may vary depending on the specific version of Outlook®. The steps above are provided as a general guide, but may vary depending on your individual version of Outlook. For detailed instructions, please refer to the cloudshift® Knowledge Base.

Exchange® uses its own database engine called the Exchange® Database (EDB). This database engine stores all emails, calendars, contacts, tasks, and other information associated with an Exchange® account.

The Exchange® Database (EDB) is a proprietary database engine developed by Microsoft® and optimized specifically for Exchange® Server. It uses a jet-based database technology called Extensible Storage Engine (ESE).

The Exchange® database engine manages the storage, indexing, and organization of data in a hierarchical structure format. It enables efficient storage and retrieval of large amounts of data in an Exchange® environment.

It is important to note that Exchange® is not based on external database solutions such as Microsoft SQL Server®. Instead, it uses its own database engine to meet the specific requirements of Exchange®‘s email and communications functions.

By using the Exchange® database engine, users can access their email and other information quickly and efficiently, while Exchange® can provide high scalability and performance in large enterprise environments.

Outlook® uses different protocols to communicate with email servers depending on the configuration and environment. Here are the most common protocols that Outlook® supports:

  • Microsoft Exchange® protocols: Outlook® is tightly integrated with Microsoft Exchange® and supports Exchange® protocols such as Exchange® ActiveSync (EAS), MAPI over HTTP, Outlook® Anywhere (also known as RPC over HTTP) and Exchange® Web Services (EWS). These protocols provide access to email, calendar, contacts, and other Exchange® features.
  • Internet Message Access Protocol (IMAP): Outlook® can use IMAP to connect to email servers that support IMAP. IMAP allows access to e-mail on the server and synchronization of changes between the server and the Outlook® client.
  • Post Office Protocol (POP): Outlook® can use POP to connect to POP3 mail servers. POP allows downloading e-mails from the server to the local computer, normally downloading only one copy of the e-mails by default.
  • Simple Mail Transfer Protocol (SMTP): Outlook® uses SMTP to send e-mails via the corresponding SMTP server. It is the standard protocol for transferring emails on the Internet.
  • Microsoft 365®/Office 365® protocols: If Outlook® is used with a Microsoft 365® or Office 365® account, protocols like Exchange® ActiveSync (EAS) or Outlook® Anywhere (RPC over HTTP) can be used to access the emails and other information.

The choice of protocol depends on the type of e-mail server Outlook® is connected to and the specific requirements and settings of the user. Outlook® supports a wide range of protocols to ensure broad compatibility with different e-mail servers and services.

Yes, Exchange® supports the Internet Message Access Protocol (IMAP). IMAP is a widely used protocol for synchronizing and managing email between an email client and the email server. It allows users to access their email on the server and synchronize changes between the client and the server.

With IMAP, users can manage emails on the Exchange® server, create folder structure, read, send, delete and move emails to different folders. IMAP also supports features such as downloading email header information, browsing emails on the server, and working on multiple devices simultaneously as email status (read, unread, flagged, etc.) is synchronized between devices.

It is important to note that in addition to IMAP, Exchange® also supports the Exchange® ActiveSync protocol (EAS) and the web-based Outlook® Anywhere protocol (RPC over HTTP). These protocols provide additional features and benefits compared to IMAP, especially for synchronizing calendars, contacts and other information. Users can choose the appropriate protocol to work with Exchange® depending on their requirements and preferences.

Yes, Exchange® still supports the POP3 protocol (Post Office Protocol Version 3) for email access. Although Exchange® is more optimized for using IMAP (Internet Message Access Protocol) and other Exchange® protocols, it also provides support for POP3.

By enabling POP3 access in Exchange®, users with a POP3-compatible email client can access their email on the Exchange® server. They can download, store locally and manage their emails. In doing so, the emails are normally removed from the server, unless the user has selected the option to leave copies of the emails on the server.

It is important to note that the availability and configuration of POP3 access depends on the specific Exchange® version and Exchange® administrator settings. In some cases, the Exchange® administrator may disable POP3 access for security or policy purposes, or set certain restrictions.

Although POP3 is still supported, IMAP is recommended for email access to Exchange® in most cases. IMAP provides synchronized and folder-based management of email, allows access to folder structures, and offers advanced features such as synchronization of status changes (read/unread) across different devices.

Users who wish to use Exchange® with POP3 should check the specific configuration settings and recommendations of their Exchange® administrator or email service provider to ensure POP3 is enabled and properly configured.

Microsoft Hosted Exchange® Add-ons

What sets us apart from other providers? Our add-ons! Over many years, we have specialized in developing cloud offerings specifically for enterprise customers. Our specially developed add-ons bridge the gap between a standardized cloud product and the specific requirements of enterprise customers for a Microsoft Exchange environment.

  • For collaboration in your team, we offer optional public folders and workgroup mailboxes for an additional €2.90 plus VAT. Both include 5 GB of storage by default, which can be expanded as needed.
  • Public folders are easy-to-manage, cross-group, hierarchical folder structures. They are suitable, for example, for sharing general email accounts, contacts, calendars, etc. They can be assigned individual permissions and are displayed to authorized users in their Outlook folder structure. A public folder can contain any number of free subfolders.
  • Workgroup mailboxes offer the full scope of a normal Exchange mailbox and maximum flexibility. Workgroup mailboxes can optionally be shared with other users, additionally be included in Outlook or on mobile devices like a normal mailbox or be used comfortably via the Outlook Web App (OWA). Like public folders, they can be used for general, cross-team data, e-mails, contacts, calendars, etc.
  • To ensure secure and binding communication with external parties, our e-mail security service is optionally available – for personalized signing and strong encryption of your e-mails. Incoming and outgoing e-mails are thus not only protected against spying, but also reliably against falsification.
  • The E-Mail Security Service takes over the complete management of the keys or your S/MIME certificates. Encryption, decryption and signing are fully automatic and transparent. System-independent and without software or hardware installations.
  • The basic service is provided for your entire account. A separate S/MIME certificate is issued for each e-mail address that is to use encryption and signing. However, this can also be done only for selected users or e-mail addresses.

Companies are required by law to archive commercial documents (including many business emails) in an audit-proof manner for 10 years (see §§ 238, 257 HGB and § 147 AO). Furthermore, a central e-mail archive ensures structured storage and backup, fast retrieval of information and effectively protects against data loss.

In contrast to back up, which is suitable for short- and medium-term storage of data and for recovery after data loss, archiving is about long-term storage of data on a separate data carrier. The purpose is not primarily to restore data in case of need, but to document it. For example, the archive also stores data from employees who have already left the company and whose mailboxes no longer exist.

The legally compliant and audit-proof e-mail archiving fulfills all legal requirements according to DSGVO, HGB, Basel II, GDPdU, KonTraG and others. Deployment is uncomplicated and requires no installations on your side. Seamless integration with Outlook and access via browser or smartphone app allows users to search the archive and restore deleted items without making changes to the archive. An auditor function is available for audits, allowing you to activate temporary access to selected areas in a 4-eyes principle.

Scope of services for e-mail archiving

  • Archiving and versioning of all e-mails
  • Indexing, full text search and recovery of deleted e-mails
  • Auditor access according to the 4-eyes principle
  • Access via Outlook, browser or iOS and Android app
  • Unlimited storage space
  • Backup in physically separate data center

Personalized signatures according to a uniform pattern are your company’s business card for every e-mail dispatch. They also meet legal requirements for unambiguous identification of the sender. But how many of your colleagues really set up signatures conscientiously and keep them up-to-date?

We offer you a solution that automatically inserts signatures at the end of every e-mail. Individual information such as first name, last name, position, department, telephone number, mobile number or e-mail address can be included for each employee. Templates allow you to differentiate between internal and external e-mails, using either plain text or HTML. You can also set up a uniform disclaimer that is sent with every e-mail.

You have questions or need an individual offer?

Our cloud experts will be happy to answer your questions about the design, implementation and operation of your applications in the cloud. We look forward to your inquiry!
