For some time now whenever I try to include a hyperlink (such as to my linktree page) in an email in Outlook I get the following message and the email fails to send.
Your message did not reach some or all of the intended recipients.

Removing the hyperlink lets the email send.
Has anyone come across this?
Please edit out the email address as well as being against forum rules, the address will be inundated with spam.
