[Caution]Caution

Only one version and bit variant of Microsoft Office products may be installed on the system. Different versions of Outlook and other Office components, as well as different versions of Outlook at the same time (as partially supported by Outlook 2013, so-called side-by-side installations), cannot be used reliably with the Groupware Client.

Also if Office related apps (including "My Office", "OneNote", and "Office Lens") are installed from the Microsoft Store, this can lead to an incompatible side-by-side installation. These apps are pre-installed on some versions of Windows and must be uninstalled via the Microsoft Store.

We also advise against using Click-to-Run installations of Microsoft Office 2013, as we have observed some Click-to-Run-related malfunctions in this version. Instead, use a fully local offline installation.
