RightFax 16.2 (RightFax 16 Enhancement Pack 2) didn't support O365 when outlook client enable cached mode

Since office 365 do not support “Foreign Connector”, it only provide “standard SMTP mail routing”, so that when using RightFax Outlook client in “cache mode” or Fax address book in outlook contact, the email cannot route to the Fax server.

RightFax Outlook client will use the email syntax similar to “[FAX:name@/FN=888]”, as this kind of format is not supported in standard SMTP routing so that it is not supported by Office 365.

Only the following conditions will work with O365:

As long as outlook users do not use the RightFax Outlook client in cache mode or Fax address book in outlook contact, and

1) use a standard SMTP syntax or

2) redirect these fax message to an email account, then adjust these message, and then redirect to Fax server.

Updated***

There are workaround:
By forwarding the exchange email domain to another email domain that RightFax connected. And it works by using Fax Number@fax domain addressing
Meanwhile use RightFax Exchange Web Service (EWS) connector to connect O365

Email Notification even if Outlook is Closed

Outlook Folders display different language characters. (Names of standard folders in an Exchange mailbox, such as the Inbox, Sent Items, Public Folders, and so on, appear in different languages when seen from the client program. )

“When user logon to any computers anywhere to access his/her Outlook through outlook client and OWA, the default folders (Inbox, Sent Item and Deleted Item) show Chinese characters and some unknown characters."

Here "chinese & some unknow charactors" are the deviation.

 

Solution is to launch the outlook using the option outlook.exe /resetfoldernames from the “Start->Run”

How to manage multiple Exchange mailbox accounts in Outlook

Some users have multiple e-mail accounts on the same server that is running Microsoft Exchange Server. Although you can only have one service in your Exchange Server profile, it is possible to access all of your Microsoft Outlook accounts without having to log on separately to each account.

To log on to one e-mail account (account A) and to have access to the mailbox for a different e-mail account (account B), follow these steps, as appropriate for the version of Outlook that you are running.

Note These steps assume that both accounts are on the same Exchange server.
