With this release, Sendent for Outlook is renamed to Nextcloud for Outlook. You'll see the new name and logo in Outlook and in our documentation. Functionality, settings, and licenses stay the same, so no action is needed. Read more about the rebrand.

New

• Rebranding to "Nextcloud for Outlook": The add-in has a new name and branding.
• Nextcloud theming: The add-in uses the accent colours from your Nextcloud server's theme.
• Domain allowlist: Admins can set which domains the add-in is allowed to work with.
• Signature support: The add-in now supports email signatures.

Improved

• Sign-in: A dialog shows sign-in progress. Sign-in finishes faster when you return to the task pane. If several sign-in windows are open, only the first one to complete is used.
• Secure Mail attachments: Files you add yourself stay in place if you leave the Secure Mail page, for example to open Settings. Each file now has a label showing whether it came from the email body or from your device.
• Sending with uploads: You can't start a second upload while one is already running in the on-send dialog, and the dialog buttons are disabled until the upload finishes. The Cancel button was removed from the progress dialog because it never actually stopped the upload.

Fixed

• Share expiry now uses the "Share expiration days" and "Number of days" settings from the Nextcloud app.
• The Secure Mail recipient list now stays in sync with the email's recipients.
• The share link is now inserted correctly when the cursor isn't in the email body.
• A Secure Mail email containing only text, with no attachments, now goes through the Secure Mail flow. The email body is attached to the Nextcloud share.
• Embedded images, such as the logo in the share snippet, no longer wrongly open the file intercept dialog.
• Embedded images are attached correctly when sending from Outlook on the web and the new Outlook for Windows.
• Replies with embedded images and long conversation history are less likely to fail and end up in Drafts. The commit author could not reproduce this issue, so this fix is unconfirmed.

Improvements

• Nextcloud Talk invitations: Talk meetings now attempt to bind attendees to their Nextcloud accounts first, only creating a public Talk link if not all attendees can be matched. A new checkbox lets you force a public Talk room when you prefer one.

Fixes

• Embedded images in replies: Replying to an email that contained embedded (inline) images alongside a long conversation history could cause the message to fail to send and drop into Drafts. These emails now send correctly.

Improvements

• Added an option to disable all file sharing buttons in the UI. This lets you run Sendent for Outlook with Nextcloud Talk only, without any file sharing functionality. You can now set FEATURES_CODES_TO_REMOVE with the value '5' to disable the Nextcloud Files integration, effectively removes public sharing and upload file button from Outlook.

Fixes

• Fixed the Skip button in the setup wizard, which now works as expected.
• Fixed an issue with anonymous sharing being disabled.
• The expiration date is now correctly set when sharing with a guest account.

Improvements

• More reliable large file uploads
  Introduced chunked file uploads to Nextcloud, improving stability when handling very large attachments.
• Nextcloud Talk integration update
  The appointment location field now automatically includes the Talk room link.
• Faster email processing with on-send
  Improved performance of on-send mail interaction, when attachment interception is enabled.

Fixes

• Nextcloud Talk appointment handling
  Fixed an issue where adding a Talk link replaced the entire appointment body. The Talk link is now correctly appended instead.

Lastly, while this may not apply immediately, it’s essential to always update your Microsoft Exchange environment with the latest manifest.xml file, if you're updating. This recommendation also applies to Microsoft 365 users.
