Use Lightroom to send photos through Outlook prevents Outlook sending ANY emails--stuck in outbocx

Thanks for responding.  Have no pending updates on either Outlook or Lightroom Classic.  I have had periodic trouble sending and receiving emails with Outlook.  After 3 staffers took 3 hours from Microsoft they finally fixed Outlook.  I had noted that the problems seemed to occur after I had sent photos out of lightroom to email recipients.  Outlook was working fine--then I decided to send a photo, through Outlook.  My emails, not just the photos, got stuck in the Outbox again.  I deleted them.  I tried going into my anti-virus software--it looked as though it had blocked something at the very minute I was trying to send.  So I enabled it to go through.  Now my emails are going out of Outlook--but I am wary of trying to send any photos to myself or others out of Lightroom.  (I note that there are two types of settings to send-- Harry Peterson or to Microsoft Outlook.  Acouple of weeks ago I called Lightroom support--they must never have people ask about this issue because they seemed to know no more about it than I did!  Meanwhile, I photoed an error message, which I have attached.  Thanks again.  Harry
