FYI add-in showing "FYI-2117" communication error

Our engineers have confirmed that this issue is not caused by FYI.

It appears to be isolated, as not all users are impacted even within the same organisation.

Based on our investigation, the issue may be related to one or more of the following:

• Office or Windows Updates: A recent update may have changed security policies or browser control behavior
• Edge WebView2 Updates: Office add-ins use Microsoft Edge WebView2 to render
• Security Software: Antivirus, firewall, or endpoint protection updates may be incorrectly flagging the dialog pop-up as malicious
• Corrupted Office Cache: The cache where Office stores add-in files can become corrupted

If the issue persists, we would recommend contacting Microsoft support to investigate further while using the following workarounds:

• Select the Finished Editing option in FYI to sync the document back
• Change the filing details from the In Tray or from the Documents workspace
• Use the online versions of the Office apps

Please let us know if you have any questions

We are aware of an issue affecting a small subset of users where the FYI add-in displays an "FYI-2117" communication error.

The issue is not widespread and the behaviour is inconsistent for those affected:

• Some receive the error in Outlook but the add-in works with Excel or Word
• Some receive the error in Excel or Word but the add-in works with Outlook
• Many do not receive an error in online versions of the Office apps but a smaller number see it with desktop and online versions
• Other users from the same practice have not experienced the issue

Workarounds:

• Select the Finished Editing option in FYI to sync the document back
• Change the filing details from the In Tray or from the Documents workspace
• Use the online versions of the Office apps

We will provide further updates as soon as possible
