Re: Launch(email, with link) issues

Sorry this took so long to respond to. There is really no way to get around the + signs since it's a related to URL encoding and we can't set the type to HTML as true on the Launch command. This means that when you need to expand to include multiple words in either the subject or the body of the email, the best approach is to use the Outook connector as explained here:


That method also answers a previous question on this thread regarding the HTML true property, which although it does not work in the Launch() function, will work well using the Outlook connector. See that key and others here:


My apologies again for the delay in my response. Let me know if you need a video demonstration of using the Office 365 Outlook Connector. Special thanks to the community member that made this recommendation earlier on this thread.


Let me know if this works for you as well,

Re: Launch(email, with link) issues

So with those people still with the hated plus issue. I have found a way around


use the special character for a space. Most special character charts go to 254. But there actual is a 255 and thats the one for a space. So using your num keypad, hold down Alt then 255 on your num keypad and you'll get an encoded space that Microsoft cant ignore and must provide that character space. 


The world did exist before Microsoft !!!


I also used this trick in creating empty lines in the nav (like double spacing it) and other places as well

Re: Launch(email, with link) issues

As Matt mentioned you can use the Unicode space character to get around this (Supported in most fonts) more info here:


If you're working from a laptop (without a num pad) you can get the character by going to the Windoes 10 seach box and typing "character map", find it in the app and select it (near the top in position #94, right after the Tilde "~") , then hit "Copy"

On Mac, use Option + Space to create space in between words for subject and body.

Re: Launch(email, with link) issues

Please also be aware of the 2048 character limit in the length of the "mailto:.." string passed to the Launch() function.


I have added a new suggestion for opening a new mail in Outlook using a new function (my suggestion Office365.CreateEmail) which would avoid this 2048 character (about 80 email addresses in my case) limit.


It would also enable the user to format the mail and make changes in Outlook before sending.


A Flow action with the same effect would also be helpful.


Here is the link to my suggestion:

Your votes would be very much appreciated. Thanks

Re: Launch(email, with link) issues

This all worked well for me, infact on my end, looks like just hacing spaces in the code now works.

now i am trying to do a line break!
any ideas out there how someone can add a serperate line break?


I can
Like This In
The Email Body


Thank you!

Re: Launch(email, with link) issues

Albeit an somewhat old thread, use Char(10) to specify line breaks / carriage returns. 


Per your example the body text of the email would look as follows

Concatenate( "So", Char(10), "I can", Char(10), "Write", Char(10), "Like This In", Char(10), "The Email Body" )
