As a Mac user, some Office features are out of our reach, which is problematic

We only needed to use support for Microsoft Office 2016 once, and it was for a minor technical problem that was ultimately determined to be user error, but the support was great, both in the online resources and the one-on-one experience we had with a specialist.

The areas where Microsoft Office shines, at least within our organization, are word processing and spreadsheets. We use Microsoft Word and Microsoft Excel on a regular basis for virtually all office tasks. Microsoft Word, in particular, is hands-down the best word processing software around, and we would never use anything else.
One area where Microsoft Office really needs to step up its innovation is with email management. We used Outlook for a long time, but have recently moved over to Canary Mail. The main problem is that we manage over a dozen email accounts for clients, and there is no way of looking at a unified inbox with some sort of color-coding or another unique identifier to easily see incoming mail. Like many creative-oriented companies, we use Macs exclusively, which means we are definitely missing out on substantial features that are only available on the PC version.
