I have listened to a few users at work and noticed that some people are having problems sending hyperlinks within emails.
This is often due to links for files or folders having spaces in them, I have tried to eliminate spaces in the file structure on the new server but this is not always possible when it comes to file names made by users.
A simple fix is available for this issue, simply enclose you hyperlink which is not recognised in speech marks (“ “).
You need to send a hyperlink to a hypothetical document we will call “sample document.doc” stored on say a share directory.
\\shared-directory\Files\sample document.doc may not always go blue with an underline (i.e. Windows does not recognise the full-link as a hyperlink)
Simply adding the speech marks as prefix and sufffix.
will sort out the spaces messing up the hyperlink for you, it also makes the speech marks disappear ( I have re-added them for clarity as you can see the link has gone blue).
