@MikeO5888 Actually, there is a workaround....
The 2K limit is, it is true, a browser-inherent limit. But not all browsers are created equal....
Chrome and Edge, for example, seem to have limits of around 2K for MailTo link text.
However, Firefox seems to have a massive larger limit. For example, I have been able to successfully generate emails from AppColl in Outlook using Firefox that have nearly 24,000 characters (5+ pages of solid text in Word).
Keep in mind that if Firefox ever reduces that limit, there is nothing AppColl can do about it. At the same time, Chrome and Edge might raise it, allowing them to be used in a similar manner....
So if you're willing to use Firefox as your AppColl browser, you should be able to have much more flexibility in terms of the size of the email template for direct creation in your Outlook client.
