We switched our company from an Intermedia Exchange server to Gmail for Business and I am extremely happy with the results.
Google Workspace facilitates collaboration with real-time editing, supported by Gmail, Google Meet, and Google Drive for productivity. It offers strong security but faces challenges with app compatibility, such as Google Docs and Microsoft Word conversions, and Google Sheets' limited functionality compared to Excel. Google Meet lacks some features of competitors, and the pricing and licensing structure can be challenging for businesses to navigate.
