Warning: Users should not open multiple tabs or windows of the browser for a single session using Travel and other services. When multiple tabs or windows are open, actions in one tab or window can change the session and cause other tabs or windows to become non-functional.

Operating Systems

Deem develops and tests on the following operating systems:

Windows 10+

Calendar Versions

Many Deem services can schedule events in your calendar, such as travel reservations. Calendar integration allows Deem to directly update your calendar with the event. This feature is especially important for delegates who book on behalf of others. The following calendar versions are supported:

Microsoft Exchange

Exchange 2016
Exchange 2019

With Microsoft Outlook, it is possible to deploy a safe-senders list by using the Domain Controller to automatically send out those domains via a Group Policy Object (GPO) and use the GPO settings to import one or more lists from a stored text file. The domains would automatically be added to each user’s “Safe Senders” list.

Junk Mail and Spam Filter Settings

Deem recommends whitelisting the following domains on the server side (such as Microsoft Exchange) and on the email client side (such as Microsoft Outlook).

*@deem.com
*@us.deem.com
*@us1.deem.com
*@statusdashboard.com

Whitelist Email Domains

Ensure all emails from the following domains are whitelisted:

deem.com
TripAdvisor.com

For international users, the following may also be needed for international top level domains:

Tripadvisor.fr
Tripadvisor.es

Note: Failure to whitelist or otherwise accommodate these email domains may cause user activation and notification (including confirmation) emails to be refused by the customer's mail server or be routed to spam/junk mail folders.

Unblock URLs

If a filter or proxy is used to restrict content accessed over the internet, the following URLs must be unblocked:

deem.com
cdn.rcobjs.com
rcobjs.com
etta.rcobjs.com
google-analytics.com
https://main.rcmsg.com
https://tealium.hs.llnwd.net
https://*.virtualearth.net

Note: Failure to unblock these URLs may prevent some pages from fully rendering.
