Samsung phone apps (samsung email/outlook) will not log into comcast email.

samsung email app has not been syncing for the past couple days and same thing on my outlook app.  I tried to re log in through both app settings and it will not connect to server. I cleared the cache, manually put in the incoming and outgoing server settings, updated apps, removed apps and reinstalled, checked to make sure third party apps was selected in xfinity profile. I am able to access email through outlook on laptop. Which is making me believe this is an xfinity issue. Anyone have a solution?
