Cannot access email

no email for 2 days keep getting error messages

This is an ongoing problem over the past month (usually in the middle of the day but sometimes during evening hours). Comcast in typical fashion for all large service corporations denies there is anything wrong. However, it is quite obvious they are either having serious problems with volume on their email servers that probably haven't been upgraded to the level necessary for keeping pace with high volume business clients, or there have been server outages and failures. I never had a problem before June and my 2-way Internet connection is fine. I know it's the Comcast email server and not "site problems" on my end since (a) I have an active 2-way Internet connection, and (b) Comcast's email server is not even pushing through content to the Blackberry server. Also, in addition to the MS client you are unable to access email via the Xfinity website (zimbra mail) or iPad remote app. Comcast should simply own up to the fact that they're either managing their network by staggering access to the server, or experiencing server problems. At least customers would know the situation and be able to manage their expectations. This constant, "oh, there's nothing wrong on our end" is absurd and it devalues the customer. If this continues consider setting up a yahoo or gmail email address as a back-up. These web based email programs are working fine during this period when the Comcast service is letting us down.
