How to Resolve the Issue Where the Add-In’s Icons are Greyed Out¶
If after installing RGES Add-In in MS Outlook, the “Open RG Email Sidebar” icon and other associated icons in MS Outlook ribbon are greyed-out, unclickable, or unresponsive, that is most probably caused by a conflict with a COM (Component Object Model) MS Office add-in, e.g. Adobe PDFMaker Office COM addin, installed locally on your PC.
Microsoft prioritizes COM add-ins over web Office add-ins. As a result, MS Outlook disables the RGES Add-In when a conflict is detected. More information about that be found on Stack Overflow.
If this is happening to you, to be able to use RG Email Sidebar, try removing the unused COM add-ins from your MS Outlook setup. If this is not possible, you might consider using the Desktop/MSI implementation of RG Email Sidebar.
