Unable to Access a Page Due to 'Value Exceeds Maximum Length' or 'Character Not Allowed' Error in Salesforce Outlook Integration

Date de publication: May 11, 2026
Description

When using the Salesforce for Outlook (SFO) side panel to open a Contact record in Salesforce from Microsoft Outlook, you may encounter the following error message:
"The value of the 'id' parameter contains a character that is not allowed or the value exceeds the maximum allowed length. Remove the character from the parameter value or reduce the value length and resubmit."
This error typically occurs due to corrupted temporary Internet files, outdated cached data, or misconfigured Internet Explorer settings that interfere with how the Salesforce Outlook Integration (SFO) constructs and passes record IDs to the browser.
Note: Internet Explorer (IE) reached end-of-life in June 2022. If you are using Microsoft Edge, Google Chrome, or another modern browser, try clearing your browser cache and cookies as a first step instead of the IE-specific steps below.
