Below blog mentions a limitation to the amount of groups a user can be a member of:
There is no limit to the number of Groups per Office 365 tenant
Each user can create up to 250 Office 365 Groups
Each user can be a member of up to 1,024 Groups
Groups with over 1,000 users are supported
Group conversations can be slow in groups of this size or greater
Public Groups can be a risk, since anyone in your organization can join them
A special Group mailbox is created in Office 365 to store all the Groups content.
The maximum size of this mailbox is 50 GB
Is this limitation still applicable or is this post outdated or incorrect?
Tx in advance.

My two cents here:
There is no limit to the number of Groups per Office 365 tenant: Incorrect, the limit is 500.000 Groups per tenant, even it could be possible to create more
Each user can create up to 250 Office 365 Groups: correct
Each user can be a member of up to 1,024 Groups: correct
Groups with over 1,000 users are supported: correct. Indeed current limit (not documented) is 2500 users / group
Group conversations can be slow in groups of this size or greater: It depends on what you understand by group conversation. Remember conversations in Groups happens in the Group Inbox that is just a EXO inbox
Public Groups can be a risk, since anyone in your organization can join them: if the group is created as public, I think there is not a risk at all
A special Group mailbox is created in Office 365 to store all the Groups content: Partially correct...when a Group is created, an EXO mailbox is created for storing Group conversations and a SPO site is created to store Group documents
The maximum size of this mailbox is 50 GB: Correct, the size for each group mailbox is 50 GB

@Juan Carlos González Martín Thanks for the quick note limitations.
Is there any change in the upper limit to users/group.
We would like to use the Office 365 group for our migrated sites from SP 2007. But each site has 10,000+ users. Not sure if we can proceed and would like to know the limit before any action.
I appreciate any update on this.

Hi all - we use Office 365 Groups to manage our projects, and we would prefer that a Service Account is the only creator/Owner of the group (all provisioned via PowerShell scripts for a consistent UX/UI across all O365 groups).
That said, there is a limit of 1024 members/owners per group - which would generally be fine... but if our Service Account is the only Owner (...as the rights are too high for normal users to have Owner rights).
I hear a rumour that MS are upgrading the limit to 2,000 Groups per member/owner - but anyone aware if it'll go higher? like 10,00 or more? Aware that such high numbers for a member/owner could produce UI or other scalability issues, but a vast increase in numbers would be good.
Anyone have any ideas on if this is being developed?
