The Sendent Outlook Add-in enables Nextcloud customers to easily and securely send files, folders or upload links to others from within Microsoft Outlook. The Add-in can replace attachments, automatically uploading files to Nextcloud and insert a secure link in the email. It also makes it easy for users to provide others with a secure file upload link.

A major new version of the Sendent Outlook Add-in for Nextcloud has been made available. The new release introduces a complete redesign of the user interface and a server app to configure a variety of settings. With it comes a name change of our partner to Sendent as well as a differentiation of the product in four versions.

The new release has a rewritten user interface as well as a number of new features.

  • New server app, allowing the admin to configure the add-in like selecting default upload folders, setting the treshold for intercepting and uploading attachments, configuring the look of the default link and more.
  • Ability to either upload attachments from the local system or selecting files from Nextcloud to share
  • Improved Secure Mail feature which uploads the email body to the Nextcloud server to protect very sensitive content. This version can create Guest accounts for users so the content and attachments of emails are always protected behind a Nextcloud login with two-factor authentication, brute-force protection, suspicious login detection and the many other security features in Nextcloud.
  • The client is now available in English, German, Spanish, French, Italian and Dutch.
  • Smarter html templates. The link that is inserted in the email can now be customized with a number of smart tags including sender and recipient name, subject and more.
  • A much improved activity tracker shows if and when the recipient has downloaded the files you sent or uploaded files to you. This is now found in the Sent Mail box.
  • A lot of cleanups and smarter behavior, including faster, parallel uploading, cleaning of mistakes and more.

just gave it a try, unfortunally without success.

first i installed the app on the server, i changed the language to german and the auto-upload-attachment-size to 20.

after some time, the app deactived itself, so i activated it again. i noticed, that the textareas for the Share Files & Public Folder were empty, i did not touch them before.

then i installed the “free outlook app”, after setting it up i tried to attach files, upload worked, but there was nothing inserted to the mail, it was still empty after the upload window closed.

i thought it might have to do with those empty snippet-fields in the configuration of the server-app, so i deactivated the app again, but it did not change anything, still no link is added to the email.

We updated the free build as of this morning (v3.0.3). Between the update to 3.0.1 and 3.0.2 a bug was introduced that limited itself to the free edition, which has now been corrected. Version 3.0.2 was released just before this weekend. (can be downloaded from same link)

Certain features as upload on-send are not included with the free edition.

In case you want to use the server-app, for now the add-in does not auto-enable the usage of the serverapp. In the registry you have to enable under:

Then at start-up of Outlook the latest settings from the serverapp will be retrieved. This behavior will be enabled default in the future.
