I hope this is not a repeat, but I cannot find my original question. Last night I left my computer on for "updates" and this morning my Eudora had disappeared, clicking on the icon sent me to Microsoft Outlook which I have never, nor will I ever, use. I have tried "delete" on the update noted in Programs - still there. I have searched Mozilla Support on nothing there seems to address what Microsoft 365 (or whatever they call it) has done, and I don't dare click on Eudora in my Programs since Lord knows what would happen there. I am elderly, as is my computer, so if anyone can help, "baby steps" please. I am so distraught - how can Microsoft do this??! Thank you in advance for any help.
