Good Afternoon,

We are aware of an issue which is preventing users on certain ISPs, from being able to access their mailbox via Outlook and Webmail (OWA).

Our Infrastructure Team are aware of this, and are investigating further. We will aim to provide a further update regarding this as soon as possible.

As a workaround in the meantime, please whitelist the following URL on your router:

messageexchange.com

Good Morning,

Our Infrastructure Team have contacted the currently known affected ISPs to assist in removing messageexchange.com from their blocklists, and we will aim to provide a further update as soon as possible.

To help expedite the process, please could affected users report as a false positive case to your ISPs directly.

Good Afternoon,

We are still awaiting further feedback from the affected ISPs regarding the delisting of messageexchange.com, and we will aim to provide a further update as soon as possible.

A workaround for this for the time being would be to whitelist messageexchange.com on your router/content filtering service your ISP provides.

Also, if you are able to assist by raising as a false positive to the ISP directly, this would help expedite the delisting process.

Good Morning,

We are still awaiting further feedback from the ISPs regarding our delisting, and our Infrastructure Team are continuing to chase up with them to help get this resolved as soon as possible.

We will aim to provide a further update as soon as possible.
