Export last log on more 90 days Office 365

Hello dannytveria,
Your error means that PowerShell is trying to use not unique value for -Identity parameter of Get-MailboxStatistics cmdlet.
For Identity parameter you can use any value that uniquely identifies the mailbox. For example:
- Name
- Alias
- Distinguished name (DN)
- Canonical DN
- Domain\Username
- Email address
- GUID
- LegacyExchangeDN
- SamAccountName
- User ID or user principal name (UPN)
In your case one of the options would be to use UPN as it is unique within your organization.
You need to modify your script to explicitly pass UserPrincipalName to Get-MailboxStatistics.
Hope that helps.
Hi Andy,
thanks for your response.
I didn`t understand where exactly I need to change value.
can you please help me with my example?
Hello dannytveria,
Try this:
Get-Mailbox -RecipientType 'UserMailbox' |%{ Get-MailboxStatistics $_.UserPrincipalName | Sort-Object LastLogonTime | Where {$_.LastLogonTime -lt ([System.DateTime]::Now).AddDays(-90) } | Export-Csv "D:\Logs\O365MAILBOXSTATS_REPORT.CSV" -NoTypeInformation -Append}Hope that helps.
- Hi Andy,
thanks for the help.
I getting a warning:
By default, only the first 1000 items are returned. Use the ResultSize parameter to specify the number of items returned.
Also, no CSV file not created maybe because of the warning?
