For the past month and a half or so Outlook 2016 will continually prompt for username and password to a point where I have to close it and re open it. It also will not sync unless I close and reopen it. This is getting really annoying. First level support was all but useless. I'm a network and email tech and have done pretty much everything on my end. including:
1. Deleting and recreating my profile, my .ost file, and any other file involved.
2. Changed my password about 5 times, this will work for about an hour then it starts doing the same thing though it still doesn't sync.
3. Verified all my settings and tested.
Basically first level support said they don't support 3rd party products like Outlook and to use the webmail. This is not acceptable. I read a similar post a couple of weeks ago where moving their account to a different email server solved the trick.
This is not an Outlook Problem. I have two email accounts set up with Cox. My wife also has two email accounts. I get the problem on only on email account. My wife does not have the problem at all. I also have an android phone and an android tablet. I have the problem on all devices. My Windows 10 PC with Outlook 2013 and both my phone and tablet using Gmail under Android 7. Some days are better than others but this problem is consistent for me on only one of the four email accounts and has been for years. I also went through the same old support routine of changing passwords and re-adding the email account to Outlook etc. The problem has been getting worse these last couple of days and today its occurring constantly. IMHO the problem seems to be on the COX server side. I bet my email account with the problem is not on the same server that our other three accounts are on. I will add that I also have two Gmail accounts that do not have or have ever had this problem. I gave up on trying to get Cox to fix this problem and am converting over the Gmail. I’m sure that Googles email customer service could be just as bad as Cox but if you don't have any problems you don't care.
Thank you Cox for years of E-Mail frustration.
