You can certainly hold the view that different service plans for individual services are the equivalent of “Pro” versions. However, that analogy only works at the lower end of the Microsoft 365 spectrum. At the level Microsoft is targeting here (Office 365 E3 and above – the enterprise), SKUs tend to have all the functionality from the higher level plans. That, along with the poor choice of features to bundle, was the point I was trying to make.

This isn’t quite accurate, is it? After all, there’s Exchange Online Plan 1 (which is part of Business Basic / Business Standard / E1) and Exchange Online Plan 2 (E3/E5) which includes IRM, message encrption, in-place hold and litigation hold, along with larger mailbox sizes – and even Exchange Online Kiosk which allows an OWA, POP/IMAP only mailbox without Outlook access. Similarly in SharePoint Online there’s Plan 1 and Plan 2 with Plan 2 adding ‘unlimited’ storage, in-place holds and litigation holds. So it’s not really a new frontier.

there is a way to be connected to multiple teams tenants at the same time. I am a member of my work, my own personal tenant and Microsoft’s as a guest and my personal as a guest of my works.. and I’m a guest in a friends own personal tenant. you use the drop down box in the app to select the tenant you want to interact with.

I’ve had a few problems with Teams personal too. So much so that I removed Teams personal from my profile. I now use Teams for work. Period. KISS is a good principle to observe (I wish the Teams devs did this from time to time).

I had a similar issue. I don’t know if you loaded Teams through company portal but I uninstalled it completely, re-installed everything and everything seems to be working normally again. This time around though, I setup a work profile and run Teams through there.

In the last few weeks, along comes a Teams invite for a meeting unrelated to work, so I took steps to set up a personal account linked to my personal O-365 account. Big mistake! Now Teams is confused because it recognizes my personal mobile # with my work account and wants me to add more software to my phone so that I can access my work Teams account. It’s still doing the 2FA part correctly, but I can’t access the mobile version of my work account.

“the service plan will be added automatically to Microsoft 365 and Office 365 E5/E3/A5/A3, and Microsoft 365 Business Standard/Business Premium licenses”.

No mention of E1/A1 users. It’s more like MS is promoting the upgrade of E1-level licenses to E3/E5 licenses ($$$). Otherwise, why not just roll out new features to all licensed users and allow control of those features via policies?
