Definitions

<DomainName> ::= <String>(.<String>)+
<EmailAddress> ::= <String>@<DomainName>
<EmailAddressList> ::= "<EmailAddress>(,<EmailAddress>)*"
<EmailAddressEntity> ::= <EmailAddressList> | <FileSelector> | <CSVkmdSelector> | <CSVDataSelector>
<UniqueID> ::= id:<String>

Create an alias for a target

gam create alias|aliases <EmailAddressEntity> user|group|target <UniqueID>|<EmailAddress>
        [verifynotinvitable]

<EmailAddressEntity> are the aliases, <EmailAddress> is the target.

The verifynotinvitable option causes GAM to verify that the alias email address being created is not that of an unmanaged account; if it is, the command is not performed.

Example

To allow Robert to also receive mail as Bob:

gam create alias bob[@yourdomain.com] user robert[@yourdomain.com]

Update an alias to point to a new target

The existing alias is deleted and a new alias is created.

gam update alias|aliases <EmailAddressEntity> user|group|target <UniqueID>|<EmailAddress>
        [notargetverify]

<EmailAddressEntity> are the aliases, <EmailAddress> is the target.

By default, GAM makes additional API calls to verify that the target email address exists before updating the alias; if you know that the target exists, you can suppress the verification with `notargetverify.

Delete an alias regardless of the target

gam delete alias|aliases [user|group|target] <EmailAddressEntity>

<EmailAddressEntity> are the aliases.

Remove aliases from a specified target

gam remove alias|aliases <EmailAddress> user|group <EmailAddressEntity>

<EmailAddress> is the target, <EmailAddressEntity> are the aliases.

Delete all of a user's aliases

gam <UserTypeEntity> delete aliases

Display aliases

gam info alias|aliases <EmailAddressEntity>
gam print aliases [todrive <ToDriveAttribute>*]
        [domain <DomainName>] [(query <QueryUser>)|(queries <QueryUserList>)]
        [aliasmatchpattern <RegularExpression>]
        [shownoneditable] [nogroups] [nousers]
        [onerowpertarget] [suppressnoaliasrows]

By default, group and user aliases in all domains in the account are selected; these options allow selection of subsets of aliases:

• domain <DomainName> - Limit aliases to those in <DomainName>
• (query <QueryUser>)|(queries <QueryUserList>) - Print aliases for selected users
• aliasmatchpattern <RegularExpression> - Print aliases that match a pattern
• nogroups - Print only user aliases
• nousers - Print only group aliases

By default, the CSV output has three columns: Alias,Target,TargetType; if a target has multiple aliases, there will be multiple rows, one per alias.

Use shownoneditable to list non-editable alias email addresses; these are typically outside of the account's primary domain or subdomains. This adds the column NonEditableAlias.

Specifying onerowpertarget changes the three columns to: Target,TargetType,Aliases; all aliases for the target are space-separated in the Aliases column. If shownoneditable is specified, there will be a fourth column NonEditableAliases with space-separated non-editable aliases.

Specifying both onerowpertarget and suppressnoaliasrows causes GAM to not display any targets that have no aliases.

Bulk delete aliases

You can bulk delete aliases as follows; use (query <QueryUser>)|(queries <QueryUserList>) and aliasmatchpattern <RegularExpression> as desired.

gam redirect csv ./OldDomainAliases.csv print aliases aliasmatchpattern ".*@olddomain.com" onerowpertarget suppressnoaliasrows
gam csv ./OldDomainAliases.csv gam remove aliases "~Target" "~TargetType" "~Aliases"

Determine if an address is a user, user alias, group or group alias

gam whatis <EmailItem> [noinfo] [noinvitablecheck]

The first line of output is: <TypeOfEmailItem>: <EmailItem>

There is additional output based on <TypeOfEmailItem>:

• User - gam info user <EmailItem>
• Group - gam info group <EmailItem>
• User Alias - gam info alias <EmailItem>
• Group Alias - gam info alias <EmailItem>
• User Invitation - gam info userinvitation <EmailItem>

The noinfo argument suppresses the additional output.

The noinvitablecheck argument suppresses the user invitation check to avoid exceeding quota limits when checking a large number of addresses.

The return code is set based on <TypeOfEmailItem>:

• User - 20
• User Alias - 21
• Group - 22
• Group Alias - 23
• User Invitation - 24
• Unknown - 59
