How to Resolve the Issue When RI Add-In Icons are Greyed Out¶
If, after installing RI Add-In in MS Outlook, the “Open Revenue Inbox” 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.
If this is happening to you, to be able to use Revenue Inbox, 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 Revenue Inbox.
