Office 365 Services

enaio® 11.0 »

The 'office365-client' and 'office365-dashlet' Office services can be used to integrate Office 365 as a dashlet in enaio® client, enaio® webclient, and enaio® webclient as a desktop application to enable collaborative work with Word, Excel, and PowerPoint documents.

You must have a OPTIMAL SYSTEMS license and one of the following Microsoft licenses: Microsoft 365 Business Standard or higher, Microsoft 365 Apps for Business, Microsoft 365 Apps for Enterprise, Office 365 E3 or Office 365 E5, and the corresponding Microsoft accounts for the users.

The Office versions require Office files in XML format. If previous file formats are to be edited, then conversion is offered and the converted files are created as variants.

The Office services are installed via enaio® service-manager and require the 'dms' service.

File Sizes

A timeout of 60 seconds as well as a size limit for file transfers are predefined for displaying and editing files.

Application Mode Size limit Comment
Word View - The only limit in terms of the file size is imposed by the timeout.

You need the following data from OPTIMAL SYSTEMS GmbH for the configuration: OPTIMAL SYSTEMS tenant ID and OPTIMAL SYSTEMS tenant secret. This data will be provided at your request.

Special characters are not allowed for tenant IDs.

  • Services configuration via the configuration files application-prod.yml of enaio® gateway and office365-prod.yml of enaio® service-manager.

  • Dashlet configuration for enaio® client in enaio® enterprise-manager.

      - endpoint:
          name: dashlet365

  id: OS-Tenant-ID
  secret: OS-Tenant-Secret
