I want to use multiple Teams accounts at the same time
LOG INTO MULTIPLE ACCOUNTS
We need the ability to sign in with multiple accounts. Many of us have several O365 accounts for various reasons (consulting, etc), and we’d need to be able to access teams directly. This is not a federation or B2B scenario, but a case where new O365 credentials have been created in another tenant for us. The app today only allows a single signed-in account at a time and that’s a blocker.

The engineering team is continuing to work on adding support for multiple accounts on desktop clients. We will first launch support for 1 work/school account and 1 personal account so users can enjoy Teams for work and personal side-by-side. Windows and MacOS. Support for multiple work accounts is still being worked on and will come at a later date.
You can track status via the roadmap here: https://www.microsoft.com/microsoft-365/roadmap?searchterms=68845.
Thanks!

1. I haven't experienced this.
2. Logout of teams and then login with different tenant ID.
3. The most obvious use case would be design, deployment, support of office365 as a service.
The case exists even for individual within organizations that own or operate multiple seperate entities that exist on their own tenant although that could be resolved by centralization. I think systems integrators and freelance consultants need this service the most. That or individuals that may to volunteer work for other organizations on the side.
The obvious problem is that with the current situation, a person is only getting notifications from one account.

In the same way as in outlook mobile for android where I can see All account activities or seperate account activities where each account is a tenant let me logged in simultaneously. The problem with logging in and then logging out is obviously separation of notification functions.
This could get messy but the reality is that many people may be pulled into other tenants for the purposes of collaboration.
Allow us to activate multiple tenants within a single.session without having the client interface coming to a grinding halt.

Suphatra,
Currently I log out of one Tenant and log into the second tenant. However, when a tenant has a separate login security page set up I was unable to log out of that tenant. This has been fixed with the latest update. If being able to change tenants was as simple as it is with Skype for Business, then that would be acceptable. If, however you could have multiple accounts on Teams that would be awesome if you could identify which tenant the team was registered with.If you are a converted Office 365 user, then it is very likely that you have Live accounts and Family Office 365 tenants. If you are a consultant, then multiple tenant is part of the process and Entrepreneurs also have multiple tenants for each of their start-ups.
Hope this helps

1. I've never had this happen with Teams specifically, but I've had issues with this and O365 in the past. It seems to be related to having one tenant using an SSO solution and the other just using the default O365 authentication.
2. Currently, I use the Teams desktop app for one tenant, and the web app for another. I can deal with not having one of them on my phone, so only one is on my phone right now.
3. My personal use case is both my day job and my part-time startup use Teams.
As another use case: Our interns attend a university that uses Office 365, when the university enables Teams I imagine they will want to be able to use both the university Teams and word Teams at the same time.

All O365 apps should have multiple account support. People don't always just work for one company. Look at MS Outlook and OneDrive app. That's the way to go!

Regarding point 3, I use 3 different O365 accounts all day every day (but struggle to do so due to the poor way in which MS authentication works in general when using multiple accounts with tools like OneNote, OneDrive etc.). I have 2 x work accounts (separate companies) and I also use an account at home. Just make the experience of working across multiple accounts similar to how easy it is to work with multiple mailboxes in Outlook and you cant go wrong. Look to Slack for inspiration, I guess. Thanks

The ideal would to allow any user with an Office 365 account or a Microsoft (Live) account to able to access Teams or Channels withing a Team in any tenant. Slack uses the concept of multiple accounts that maps to different URLs (ex: https://team1.slack.com, https://team2.slack.com) but users only have to have create a single account using a work email or even a personal email like Gmail and they log in into any Slack account with that single account which allows users from different companies to easily collaborate together.
In Microsoft Teams, the need to be able to access any team from any tenant using the same account (that is the real need here) could be solved by allowing any user from any Office 365 tenant or with a Microsoft account to be able to access any team in any tenant, without the need to have multiple accounts (ex: https://company1.teams.microsoft.com, company1.teams.microsoft.com), and use https://teams.microsoft.com or any client app (mobile or desktop) to access any Team or Channel they belong to in a central way. Example (I work at company 1 with an Office 365 acount that is my primary Office 365 account):
- Teams would allow authentication to be done with an Office 365 account or a Microsoft Live account as it does with SharePoint Online to access for example Office 365 groups
- As a member of company 1, I would have access to all teams I am part of in my company (as it happens now)
- As an Office 365 user, I would also have have access to Teams or Channels from other tenants that were shared with me
- I would be able to share Teams or Channels with other tenants's Office 365 accounts OR with Microsoft Live accounts
- Users using Microsoft accounts would have access to Teams or Channels from any tenant that were shared with themDoes this sound reasonable?

I'm a consultant that works on multiple projects from multiple clients. In slack, I can join multiple teams and switch between them in the same application. Right now, I cannot log into multiple team accounts on the same computer. At the very least, let me run multiple team sessions.

Kazzan commented
1. I do not see this issue.
2. I have separate VM where I sign in as RDP app.
3.. As a consultant, I sometimes need to consult, share and collaborate with other companies. Also, my customers also cooperate between companies which have separate tenants in other countries. -
Ben Stegink commented
1. This is not an issue for me
2. My company does consulting for Office 365. I have several clients all using teams. In order to chat with them in teams I need to have a whole bunch of browsers open or constantly sign in/out to switch between various teams. I would love to be able to use the Teams client and be signed into all the various clients teams simultaneously. The one thing that would eliminate the need to do this, was if clients could invite my primary Office 365 account to their team as an external user. That was I could sign into teams with my primary Office 365 account and be able to access all of the teams I've been invited to as an external users. This actually ties directly into the other request you ask for feedback around as to why I use Skype for Business and teams. I'm sure you can see the connection, but I'll respond over there as well.
3. Office 365 Consulting/Support where I have clients that would like to be able to communicate with me through teams.

I have five different accounts all with Office 365 - different identities working with different people. I am CONSTANTLY signing in and out of Teams, Groups, Skype for Business, SHarePoint, Office documents - it is a complete nightmare.
But the REASON you need to pay attention to this is that I have PAID YOU FIVE TIMES as well - so come on and fix this

I have multiple email accounts on different domains. I'd like to be able to sign into other accounts. Slack lets you sign into multiple different accounts.

1) Yes, on I phone app. No, on web browser.
2) I'm working on several projects for different organizations / companies which use Office365 and Teams. I'm running myself two companies, where I/we use Office365 and Teams for internal communication. It is a hazzle to swtich all the time between different accounts and stay informed.
3) IT consulting for different customers, organize own projects/organizations. -
Chris Ayers commented
1) no
2) I am a consultant. My consulting firm uses teams for communications. I am at a client. I have been there for about a year. They also use teams for communication. With slack, I can sine into multiple sites/accounts/teams without issue. With teams I have to log out and in back in multiple times to check messaging. This is also an issue on mobile.
3) IT consulting -

Hi Suphatra,
Thanks for collecting suggestions and feedback.
Requirements management is not an easy job.
Teams is basically a Chat tool with some sharing. Clearly a Chat tool has to be "ON" all the time. So if I am part of 2 teams in different organizations, logging in / out all the time defeats the purpose of the tool.
There is a real workaround for Azure administration for example, you just open as many "In Private" sessions of the browser as needed. Not here because Team is an App, not a Web Site.
So at least being able to start multiple instances of the App and logging each on a different account is really a basic feature that is missing, not a potential improvements.
I suggest you start by allowing multiple instances of the App to run at the same time.
Then consider functional improvements like inviting people from outside you tenant, which is a completely different requirement imoo.

@Suphatra, I think the request is an outcome of the success of Office 365. Many people work with others in different organizations where both orgs use Office 365. They are on teams together which may be housed in one org or the other and they would like to use Teams for all of them. As someone below said - like Slack.
As a consultant who works with dozens of clients, I'd love to be able to "Team" with them in one place. Right now, it means signing in and out of tenants all day long (even with different "people" set up in Chrome and other tricks). Teams seems like a natural place to allow this sort of quick communication - as well as deeper conversation and file sharing - to happen.

Our organization has our own Office 365 Tenant, but we have contracts and partnerships with a number of other organizations, many of which also have their own Office 365 Tenants. Off the top of my head, we work with at least four other Office 365 tenants and have resources at each. This forces us to use a variety of work-a-rounds. Some things are still just not possible in this environment (or not simple), such as multiple Skype for Business windows.
I believe the problem is bigger than just Teams. Ideally, the Office 365 environment as a whole would support cross-tenant use like Skype for Business does (when enabled). To be able to access and share across OneDrive, Teams, SharePoint, Projects, etc. between separate Office 365 tenants would make all the difference in the world.

Do what Slack does. :) You can be logged into however many "teams" you want. And again, why are you asking what kind of work that would require that? It's not for Microsoft to understand why customers would want to do something. It's a feature that is being requested. And it's also a feature that is currently handled by all the main competitors like Slack and Google Hangouts.
The comments thus far seem to touch in a couple of different definitions of this ticket.. some about you being involved in multiple "tenants" (which I guess would translate into multiple Office 365 business accounts) and some that are talking about having external parties connected (not included in the tenant's Office 365 account).. but both are legit and necessary and both are supported by Slack.

Also I totally Agree with Kristoffer. many of my customers are asking for this ( maybe this is what we will get when teams will be allowed to users not in the tenant
But basically for me the ideal concept would be interconnection between tenants as follow
USER 1 from TENANT 1 is working on TENANT1-TEAM 1 (in his tenant ) TENANT2-TEAM2 ( in another TENANT)
USER 1 needs to share his team or channel with User 3 from TENANT 3
USER 1 needs to access the TENANT2 -TEAM 2USER 1 creates a link ( or Share Button) that he can send to USER 3 : User 3 can insert this link in his TEAMS app so he can access the TENANT1-TEAM1
USER 2 from TENANT2 creates a Link from TENANT2-TEAM2 and sends it to USER 1
Final situation
USER 1 :
- Can see/ access TENANT1-TEAM 1 ( from his tenant) and TENANT2-TEAM2 ( from another tenant
Each user can interact with the others in their own team client without having to connect to other Team portals (and can see all alerts etc... in once central place)

Currently we are not able to collaborate with external partners / customers in Teams. In some cases, our customer might create an O365 account for us on their tenant so that we can contribute / collaborate on files, see communication history etc. We need to sign in and out of the various accounts to check whether there has been any activity and any action for us to take. This could lead to delays in us responding to important issues. Understand this is an edge case, but until true external collaboration is available, it is what we have!
