Check provisioning naming limits

Check which characters Microsoft allows in the names, descriptions, mail nicknames and site URLs of the Teams, groups, sites and communities you provision. Use it when you set a naming prefix or suffix in a Provisioning Template, or when a provisioned name comes out different from the one requested.

Before you begin

• Your Rencore role includes the Create Provisioning or Edit Provisioning permission to change a Provisioning Template. Owner, Admin and Contributor have them. See Rencore roles.
• Provisioning is part of the Premium and Enterprise Plans.

Steps

1. Find the service and the field you are naming in the sections below.
2. Check the name against the allowed characters for that field.
3. Change the prefix, suffix or requested name so it uses only allowed characters.

Teams name and description

Allowed:

• ASCII character set 0-127 except the following: { } < >
• Asian, Latin, Cyrillic, Arab, Greek, etc.
• Emojis.

Teams Microsoft 365 group mailNickname

If you do not specify a custom mailNickname, it is generated from the team name.

Rule	What happens otherwise	Example
Only ASCII characters 0-127, except @ ( ) \ [ ] { } " ; : < > , and space	Characters that are not allowed, and non-ASCII letters, are removed	Name “사과” gives an empty mailNickname, so a generated one is used, such as “msteams_d4g67o”
Must not start with a symbol or a number	Symbols and numbers at the start are removed	”_test_name” becomes “test_name” (underscore is allowed, but not at the start)
Must contain at least one letter	Replaced with “msteams_XXXXXX”, where X is a-z or 0-9	”…” becomes “msteams_XXXXXX” (underscores and dots are allowed, but not on their own)
Must not be empty	Replaced with “msteams_XXXXXX”, where X is a-z or 0-9	An empty mailNickname becomes “msteams_XXXXXX”
