What was the query to put in? This is common if the response from the tools being used are too large, it’s hard to fix but I we can work on a few, did you try to restricting your search to be more specific?

I stored the issue in my Canvas. Here is what Delegate said about the issue for your reference.
Issue 1: Cannot Send Email Through Outlook
Status: Unresolved
Description: Email send operations via Outlook integration fail silently. The tool returns no error, but emails do not appear in the sent folder and are not received by recipients.
Note: Calendar events had a similar issue but turned out to be a sync delay. Email may also work with delay - awaiting confirmation.
Update (01/09): Investigated permissions. The outlook_send capability is granted, but Outlook mailbox is not available as a shareable resource type in Delegate. Valid resource types do not include outlook_mailbox or similar. This may be a platform limitation causing email send to fail despite having the capability.
Update (01/09 - Retest): User added Outlook as a resource and retested. Email still not working.
All Outlook capabilities granted: outlook_send, outlook_reply, outlook_browse, outlook_manage_inbox, outlook_manage_drafts, outlook_view_contacts
Outlook added as a resource
Tool returns no error (success)
Email not appearing in Outlook sent folder
Email not received in Gmail inbox
Conclusion: This is a silent failure — a bug on the Delegate AI platform. The Outlook email send appears to succeed but nothing is actually sent. Needs escalation to Delegate AI team.
