Mimecast Outlook Client 5.3.1139.13090 Released

TGH Profile Image 512x512

Mimecast have now released version 5.3.1139.13090 of their Outlook Client.

This version of the MSO client now supports the following:

  • Archive Search optimizations when dealing with large archives
  • SMIME support for Citrix environments
  • Improvements to Managed Senders workflow
  • Minor UI updates
We have tested this version with Outlook being open during the install and although we do not recommend doing this, it does seem to work so long as you restart Outlook at some point to enable the new version to load.
To push this out using SCCM or Group Policy, we recommend using the MSI command below:

 msiexec.exe /i "MSOInstall.msi" /qb /norestart  
What this will do is to firstly run the installer, then the /qb will show a basic user interface without user interaction, but will stop and show the error if, for example, Outlook is still open. The /norestart is fairly simple – this will ensure that your client machine does not automatically restart itself.
