Download Email Attachment activity not downloading files with spaces in filename (Graph API)

Help Activities

Hi Team,

I’m facing an issue with the Download Email Attachments activity (UiPath.MicrosoftOffice365.Activities- Version: 3.4.10) for Outlook.
The activity is unable to download attachments when the file name contains spaces.

Example:

  • File: Invoice 123.pdf → :cross_mark: Not downloading
  • File: Invoice_123.pdf → :white_check_mark: Downloads successfully

I’m looking for a solution that works without renaming the attachment in Outlook.

Additional Information:

  • Environment: UiPath Studio 2024.10.15 LTS
  • Integration: Outlook Office 365 / Graph API
  • Inline attachments excluded: Yes

I gave a try in my Studio 2025.0.176 and it worked.
Can you try the same by using this installer https://download.uipath.com/UiPathStudioCloud.msi ?

Previously, I tried downloading the attachment by filtering with the exact file name, but it didn’t work. After changing the filter to use a wildcard (*) for the filename, I was able to download the attachment successfully. However, I feel this might be a bug in the Download Email Attachments activity, as it seems to have issues handling filenames that contain spaces.

What is the filter that you used?

Try to replace the spaces with %20 as that is using a Rest API call in backend.
