1 min read


Please find the list of compatible email clients below. Note, it’s recommended to update your email client to the latest version for the best experience with RG Email Sidebar.


Pay attention that starting from June 2022, Microsoft ceased support and updates of the Internet Explorer 11 desktop application on most versions of Windows 10 and encouraged its customers to move to other browsers. Since the MS Outlook 2013 for desktop uses Internet Explorer 11 engine to render embedded add-ins in its interface, it will be impossible to run RG Email Sidebar on this version of MS Outlook.

Email Client Supports Sync Engine Supports Add-In
Microsoft Outlook 2016, 2019 for Windows Yes Yes+Pin*
Microsoft Outlook 2016, 2019 for Mac Yes Yes
Outlook app for iOS, Outlook app for Android Yes** No**
Any other desktop or mobile client 
that can be connected to Microsoft Exchange 
and supports folders and/or categories, e.g. iOS Mail App
Yes No

* What ‘Yes+Pin’ means? the Add-In’s Sidebar can be ‘pinned’, that is, set to open automatically for relevant items you select, so you will not need to open it every time when browsing emails or meetings in your email client.
** Presently, due to a limitation in MS Outlook Mobile, in MS Outlook for Android/iOS the Add-In can be used with Office 365/ accounts only. However, your data can be exchanged with Salesforce using RGES sync (through auto-syncing or the custom “Salesforce Emails” folder).


If your email client is Microsoft Outlook for Windows, please make sure the latest version of MS Edge is installed in your system because it is used to render the Sidebar in Outlook




Since RG Email Sidebar is a cloud solution, if used via Outlook on the Web it can run in a browser. Please check browser’s compatibility and update your browser to the latest version for the best experience with RG Email Sidebar.
