I purchased MS Office 2019 for my new computer in 2021. The Install went well and all was good. A little over a year later Outlook stopped being able to sign into the Comcast email. Talking to Comcast tech after several... different trials we found by deleting the Comcast account and reinstalling it fixed the problem. About a month later the problem happen again. The delete and recreate the account trick did not work. Comcast indicated it was a MS Outlook problem since my iPhone that uses the same interface and the webmail portal all worked with the account. I then contacted Indigo about the issue. I got an email the next day asking for the order #. A few days later a email with YouTube video links on how to setup the Office software. I replied with a second more in depth description of what had been tried to resolve the issue. I have not heard from them in a week now. I can't imagine someone dealing with this lack of responce if their business depended upon it. Fortunetly for me, it is just for home use. The problem may not be MS Outlook, but you have to be able to get the support / knowledgebase to work thru to the solution.Edit: As soon as I checked my email, Indego had responded with a proceedure to reinstall Office and make sure no other office products were installed. It worked and Office is resyncing with the email account now.read more
