Workgroup integration cannot be used to create Microsoft 365 Groups when workgroup name is longer than 54 characters. Microsoft 365 Groups are assigned email addresses that comply with internet standard limitation of 64 characters or less. When a workgroup is linked to Microsoft 365 group, a default name is assigned like <wgms-wgstem-wgname>.
If you wish to link a workgroup with name longer than 54 characters:
- Option1
- Create a new workgroup with a short(er) name
- Add desired members and admins in the short name workgroup
- Link the short name workgroup to Microsoft 365
- Option2:
- Create a new workgroup with a short(er) name
- Nest the long name workgroup under the short name workgroup
- Link the short name workgroup to Microsoft 365
