RTF Messages


During a continuity mode, Rich Text Format (RTF) message are not supported for transmission. Hyperlinks may be received as exploded links when transmitted as RTF format in continuity mode. 


HTML or plain text are supported formats during a continuity event. 


Reply All in Continuity Mode


If you receive a message that includes a number of recipients during a continuity mode, and reply using "Reply All", the sender is included in the "To" list. The sender is also sent the reply when the message goes out.


Distribution Lists


Email servers may provide Distribution List (DL) functionality to group any number of mailbox addresses together within one email address. For example, the DL address may contain several other mailbox addresses, so that when Mimecast delivers the email to the address, the email server sends a copy of the email to all members of the DL.


As this feature is provided by the email server, during a continuity event messages will be delivered to the DL address, but not to the individual mailbox addresses contained in the DL. Depending on the needs of the organization, administrators may choose to provide these DL members with the option to delegate mailbox access to the DL address. During a continuity event, end users are able to access the DL email address via one of the Mimecast user applications.


Sorting Messages in Archive Folders


When sorting messages in replicated folders, you need to ensure that the Sort in Groups option is not enabled. Otherwise sorting emails by Date, From etc., will result in emails being arranged in separate groups.


Multiple Instances of Mimecast for Outlook for a Single User


Currently you are only able to have one authenticated session running per user. If the user creates multiple connections to Mimecast for Outlook the session will hang, as these two instances of Mimecast for Outlook are essentially competing for that single session.


Third Party Applications and adxloader Conflicts


Mimecast uses the Add In Express product to integrate with Microsoft Outlook. As this is a common method used by many third party apps, conflicts may be experienced and Mimecast for Outlook may not be permitted to communicate successfully with Mimecast.
