The script was working fine yesterday, however, today I'm getting the error below when trying to connect to the SCC service. I'll note "compliance.protection.outlook.com" without the ps. does resolve, I tried to find where this was in the module code to test, but couldn't seem to track it down for some reason.

connect-ms365 -Service SCC
Connect-SCC : Could not connect to SCC.
Connecting to remote server ps.compliance.protection.outlook.com failed with the following error message : The WinRM

When modules have been installed once, they don't get updated, although newer versions are available and maybe necessary based in Microsoft's online services.

Describe the solution you'd like
Test-MS365Module should check the version as well and suggest an auto-update if newer version is available.

Additional context

• Test-MS365Module checks version installed (Get-Module -ListAvailable) and available online (Find-Modul)
• calls new Function Update-MS365 to update module

Connections will be done to the default tenant / organization of the user provided.
With that CSP connections for admins managing a delegated organization are not possible.

Describe the solution you'd like
Having a possibility to select / give a tenant or delegated organization when logging in.

Additional context

• depending on module if possible or not, to be investigated
• tenant / organization inputs possible
  • manual (not that nice because of string names / tenant ids to be provided)
  • configured tenant / organization (needs configs for one time setting of complicated values as tenant id)

Describe the solution you'd like
Please add SkypeOnline support. There is a lot of Teams related things that can only be done via Skype.

Describe alternatives you've considered
I currently use a wrapper for New-CsOnlineSession, integration would be great.

Describe the solution you'd like
I want to be able to provide a list of services I want to connect.

Additional context

   Check e.g. with using Get-Module Az -ListAvailable and Find-Module Az to compare version numbers.
2. Run Connect-MS365 -Service Az
3. No notification on available module update is shown

Expected behavior
On connection it should be printed that a new version is available and an inline update is proposed.

Microsoft has announced deprecation of MSOnline and Azure AD PowerShell modules.
Old modules will still work but do not receive any further development or updates.
Microsoft is encouraging everybody to migrate to Microsoft Graphi API SDK to manage Azure AD and Microsoft 365.

Describe the solution you'd like
Add support for Microsoft Graph PowerShell to enable users to use Microsoft Graph API powershell module within Connect-MS365.

Describe alternatives you've considered
I cannot really follow Microsoft's argument that Graph API will "simplify" Azure AD management as the authentication and request handling is much more complicated and advanced. Additionally, it seems that no dedicated prepared CmdLets exists for management of users, groups, etc.
Hence, I think that most users will still use the deprecated modules for simple administration tasks. Alternatively, other management tools may cover authentication and connections themselves. So it is questionable how important that feature is for 'Connect-MS365` at all.
