Microsoft Teams – Upgrading from Family to Business

Current Environment
-Mac osMojave
-Office 2016 Suite of applications (Word, Excel, Outlook) on several machines
-Microsoft 365 Family (formerly 365 Home) – which I’ve had for several years now ($99.99/yr)
-Hosting of through IONOS

-Have Outlook mail (50GB) hosted by Microsoft, so I’m not limited by local IONOS database
-Integrate Microsoft Teams for working with clients (chat, web-conference, etc)
-Have Teams interactions with each individual client – 1:1 ratio
-Publish my calendar for bookings
-Have files uploaded/downloaded to OneDrive (MP3 audios, articles, client paperwork)
-Have access to OWA for Outlook 2019 via browser
-Continued ability to have local applications (Word, Excel, etc) installed on Mac/Windows

Microsoft Teams – Free Version
-Using same email address domain I currently have with 365 Family, I created a free Teams account.
-Q: What limitation is there for free version re: number of teams?
-A: Is it 300?
-Q: When I added a member/guest,their username is their email address, which complicates lookups for chat. Can their username be renamed, or is this only with the pay version?

Microsoft Teams – pay version through Microsoft 365 Business Basic
Q: Is there a difference in the number of people total of 300?

Outlook – version and via web-browser
-Currently using Outlook 2016 for Mac locally installed
Note: I’m accessing a mail database on IONOS via IMAP
-Would like to maintain osMojave, so as to avoid any drama with upgrade to osCatalina
-Have used gmail for years via web-browser, and will continue to use
-Ideally, I have the latest version of Outlook (2019) via web-browser
-My understanding is that I would go to this URL if IONOS was hosting –
-Q: Is Teams integrated within the web app of Outlook 2019?

Microsoft Bookings
-This feature starts with Microsoft 365 Standard and is an interface for customers to schedule and manage appointments.

Which version of Microsoft 365 to migrate to?
-Microsoft 365 Business Basic is out because it doesn’t include local applications
-Microsoft 365 Business Standard has web and mobile version; 50GB for email with your own domain name; publish calendar, share available meeting times, schedule meetings; store and share files with 1TB of OneDrive, share files with external contacts – guest links, secure down the access; host online meetings, chat with team member, integrate with MS-Teams; maximum number of users = 300.
-Microsoft 365 Business Premium appears overkill for my needs; some additional advanced security features.

Which vendor would be preferred? (Microsoft, IONOS, CDW)?
-The domain is currently managed by IONOS, but I don’t use the MS-Exchange feature yet, which I believe is the purpose of Microsoft 365 Business
-Q: Is there an advantage to change to the Business plan thru IONOS?
A: You get support from IONOS – but it’s relatively limited IMO

Number to contact IONOS re: Microsoft 365 Business Standard
(866) 289-5039 (8AM to 5PM) – Eastern

Pricing comparisons of Microsoft 365 Business Standard
OK Note: I currently have Microsoft 365 Family for $99.99/yr
-Microsoft: $12.50/month; try free for a month; that works out to a recurrent $150/year (12 * $12.50)
-IONOS: 3 months free, then $14/month; for first year that’s $126 and then a recurring $168. Even though there is an additional $18 difference with IONOS, it’s maybe advantageous to consolidate with them, considering they manage my domain names.
