Bug: UiPath.MicrosoftOffice365.Activities v3.8.11 - "Shared Mailbox" validation error

Description:

After updating the UiPath.MicrosoftOffice365.Activities package from version 3.7.10 to 3.8.11, a breaking change/validation error was introduced regarding shared mailboxes.

Email activities now throw the following validation error and warning:

“One or more children have validation errors or warnings”

“You must provide a value for shared mailbox”

Expected Behavior:

In version 3.8.10, this validation error did not occur, and the activities executed successfully without strictly requiring a value in the shared mailbox field under these conditions.

Actual Behavior:

Upgrading to 3.8.11 immediately breaks existing workflows with the validation errors mentioned above.

Steps to Reproduce:

  1. Create a workflow using

    UiPath.MicrosoftOffice365.Activities

    v3.7.10 with email activities.

  2. Update the package to v3.8.11.

  3. Observe the validation errors appearing on the email activities.

Workaround used:

Downgrading back to version 3.7.10 resolves the issue.
