Trying to send resumes. It worked on other computers.
Have Windows 10 do not have microsoft 365 which is why we have libreoffice 6.3 now. [Original document was created and saved on microsoft word. And has been edited and saved on libreoffice 6.3 a few months ago] It was able to be opened and attached with the paperclip icon with no problem to aol.
Have you tried adding your documents as attachments from the AOL or Hotmail web pages themselves? I do this frequently with both services and with both Libre and MS documents with no problem.
Looks like a duplicate of 310003/attaching-libreoffice-63-saved-files-to-hotmail-aol-outlook-are-not-attaching but contains more information.
Opera and M$ Edge are not mail applications but internet browsers. Consequently, you can’t send mail directly from LO. This feature works only with mailer application. Webmail interfaces are services which need first to be activated. This activation is beyond the reach of LO (there is no standard about it).
