It is important to note that Mimecast Mobile for BlackBerry does not attempt to replicate all email features supported by your BlackBerry device.  Instead, it provides a finite set of tools that let your users receive, reply to, and send business critical email during DR events, as well as interact with their personal Mimecast archive.


Known Limitations

Please note the following limitations:

  • Email application encryption settings are not supported
  • Read and delivery receipts are not supported
  • Email signatures are not supported (Mimecast Stationery however will be appended as normal)
  • Modifying the Importance of an email is not supported
  • Calendar invitations are not supported
  • During DR mode, if the full body or attachment for non-DR emails has not been downloaded, then users will only be able to display the part of the message which was fetched.  You will not be able to download the rest of a non-DR email if the BES server is not available.
  • If the BlackBerry user has only a mobile connection available and receives a call, the BlackBerry client will be unable to connect to Mimecast until the call ends.
  • On BlackBerry devices running OS versions 4.6.x and 4.6.1.x, it may take two attempts to open an attachment from a DR email, once successfully downloaded.
  • On BlackBerry devices running OS versions 6.x and 7.x, any emails saved as Drafts on the BlackBerry device when the Mimecast Mobile for BlackBerry client is disabled (manually or due to critical battery levels), will not be sent when the client is re-enabled. These emails will need to be composed once again and sent with the client enabled.
  • On BlackBerry devices running OS versions 6.x and 7.x, duplicate emails will be sent if the BlackBerry device still has connectivity to the BES during the Continuity event. Mimecast recommends that email redirection be disabled via a BES policy when running a Continuity event with the BES server available.


When installing and implementing Mimecast’s BlackBerry software, it is important to be aware of some of the known incompatibilities between the plug-in and specific BlackBerry Enterprise Server (BES) policies. These are detailed below, and include behavior and workarounds where possible.
