Outlook Add-In
The Firefish icon is greyed out

Solution:
Ensure an email is selected in the reading pane. Enable this via:
View > Layout > Reading Pane > Show on the right/bottom.
I receive a 'Could not sign in. Please try again' message

Root Cause: Incorrect or outdated credentials.
Steps to Resolve:
- Verify your Firefish URL—copy from your login page, excluding /login.aspx.

- Re-enter your Firefish username and password.
- Still failing? Reset your password using "Forgotten Password" on the login page.
- Try authenticating via https://outlook.office.com.
I have opened the add-in but it's showing as blank!
Solution:
Right-click in the blank space and choose Reload, or press Ctrl + F5 (Cmd + F5 on Mac).
I uploaded a candidate but there was a problem with the attachment?

Cause:
Attachments must contain a security token—if missing, they won’t upload.
Fix:
The candidate will be created, but the document must be uploaded manually in Firefish.
I'm using a shared or public inbox
Note:
Shared/public inboxes are not supported by the add-in. Limited functionality or errors may occur, and support is not available for these cases.
Candidates Surname is duplicating in First Name
Cause:
Dragging text doesn't register correctly.
Solution:
Paste the full name into First Name, use Ctrl + X to cut the surname, then Ctrl + V into the Last Name field.
Uploading from Sent Items
‼️ Important:
The add-in reads the email header, so when uploading from Sent Items, it identifies the sender as the contact.
This can lead to:
- Email being linked to the wrong record.
- Candidate/contact email being overwritten by the sender's.
Workaround:
Avoid uploading directly from Sent Items when accuracy is crucial. Instead, forward the message to yourself and upload from your inbox.
Outlook Classic vs New Outlook
🗒️Note:
New Outlook is still in Beta and not fully supported.
Recommended Steps:
- Authenticate using Outlook Web.
- Fully restart New Outlook Desktop.
- Expect intermittent changes—Firefish will update compatibility once New Outlook exits beta.
Gmail Add-In
Content not available for this message?

Reason:
Gmail can't display emails without an SPF record.
Solution:
The email sender must ask their IT team to add SPF records.
I'm receiving a Blocked Sign-in attempt notification

This is Gmail's security system blocking unfamiliar sign-ins.
Steps:
- Click Check Activity to review and approve the attempt.
