E-mail is not working with Avast enabled

[REDACTED]

Hello,

Used to work fine till today. We aren't able to send or receive e-mails with Avast enabled. If I disable it, e-mail works fine.

I get error 0x800CCC0F.

Is there anything I can do to get it fixed without disabling Avast in every computer of the organization?

We are using Avast 12.3.2515 build 12.3.3154.0 with virus definitions 170130-0.

Thanks.

There's something wrong with Avast approach to email filtering. We had our Exchange failing 4 times so far to send or receive emails. Repairing Avast helped for a day. The only way was to execute on Exchange disable-transportagent "avast plugin for exchange" command and then restart Exchange Transport service. Once Avast stopped filtering, all was fine.

I don't think Avast for Exchange is mature enough at this stage. We look after 17 Exchange servers and won't be using it after 30 days trial. Just too many problems.
