If you are composing an email in a Write window, then the added url will look like text at this point because it is easier to edit. This is normal.

If you save as a draft and then check the saved draft, you will see that it should have changed to a clickable link. So the message you send will send with a url as clickable link.

No it's incoming email that its not showing as a clickable link, just text?

In the source code a link is contained in a

<  a  href = link text and closed with a < / a >

Select email and clickon 'More' > 'View source' to see the code. Was the link sent correctly with that code.

What version of Thunderbird are you using ?

78.1.1 Just downloaded to try it.

Also It didn't bring over my folders from MS365 which makes Thunderbird not useable.

I guess I'm stuck with Apple Mail.

I presume this is an imap account, is the mail account itself still there so allowing you to subscribe to see folders?

• Right click on mail account and selct 'Subscribe'
• click on 'Refresh'
• Select folders and click on 'Subscribe;
• Click on Ok

Or do you see the folders as well, but they lack content? See if this requires a repair.

• Right click on folder and select 'Properties'
• click on 'Repair folder'
• Click on OK
