DESCRIPTION

Use the Update-M365SharedMailboxes cmdlet to update shared mailboxes in a Microsoft 365 tenant.

See the Notes section for cmdlet requirements.

EXAMPLES

Example 1: Validation only

Update-M365SharedMailboxes -ConfigNode Target -Csv 'shared_mailboxes.csv' -ValidateOnly

This example validates all data for the shared mailboxes in the shared_mailboxes.csv file but does not perform the operation. This is a recommended first step so any warnings can be addressed first.

Example 2: Basic update

Update-M365SharedMailboxes -ConfigNode Target -Csv 'shared_mailboxes.csv'

This example updates all shared mailboxes from the shared_mailboxes.csv file.

Example 3: Advanced update with translation

Update-M365SharedMailboxes -ConfigNode Target -Csv 'shared_mailboxes.csv' -TranslationCsv 'translations.csv'

This example updates all shared mailboxes from the shared_mailboxes.csv file. Data is translated according to the mappings provided in the translations.csv file.

Type: String
Parameter Sets: Action
Aliases:

Required: True
Position: Named

-IgnoreErrors

Validation errors stop execution prior to the update by default. Use -IgnoreErrors to proceed with error records omitted.

Note that global errors are not impacted by this option.

Accept wildcard characters: False

-SkipValidation

Skips the property validation stage of the import. Data supplied in the via the -Csv parameter will be used as-is, which may lead to runtime errors.

Type: SwitchParameter
Parameter Sets: Action
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-TranslationCsv

The path to the CSV file containing translation mappings. The file must use SourceName;TargetName as the field identifiers.

Type: String
Parameter Sets: Action
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False

-ValidateOnly

Validation and update are both performed by default. Use -ValidateOnly to perform the validation but skip the update.

It is recommended to run a -ValidateOnly pass first to identify potential issues prior to updating data. Note that records with validation errors will fail to update unless -IgnoreErrors is used, but records with validation warnings proceed without the data triggering the warning. A -ValidateOnly pass allows you to inspect these warnings before data is written and make any necessary changes.

Type: SwitchParameter

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
