User photos aren't synced from the on-premises environment to Exchange Online in a hybrid deployment
Original KB number: 3062745
You have a hybrid deployment of on-premises Microsoft Exchange Server and Exchange Online in Microsoft 365. When you change a Microsoft 365 user's photo by accessing that user's on-premises information, the change isn't synced to Exchange Online. For example, when the user views the photo in Outlook, Outlook on the web (formerly known as Outlook Web App), or Skype for Business Online, the user's previous Exchange Online profile photo is still displayed.
thumbnailPhoto attribute is synced from the on-premises environment to Azure Active Directory (Azure AD), the following things could cause this problem.
thumbnailPhotoattribute can store a user photo as large as 100 kilobytes (KB).
- Exchange Online accepts only a photo that's no larger than 10 KB from Azure AD.
Set-UserPhoto cmdlet or Outlook on the web to change the user's photo. These methods enable you to upload a photo that's as large as 500 KB.
Use the Set-UserPhoto cmdlet (for admins)
To use the
Set-UserPhoto cmdlet to change a user's photo, follow these steps:
Connect to Exchange Online by using remote PowerShell. To do this, follow these steps:
To use the
Set-UserPhotocmdlet to its full size capabilities, you have to change the connection URI by appending
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/?proxyMethod=RPS -Credential (Get-Credential) -Authentication Basic -AllowRedirection
Import-PSSession $Session -AllowClobber -WarningAction SilentlyContinue -ErrorAction SilentlyContinue
For more information, see Connect to Exchange Online PowerShell.
Run the Set-UserPhoto command to change the user photo.
Use Outlook on the web
For more information about how to change a user photo in Outlook on the web, see Update my photo and account information in Outlook Web App.
Admins can use the
Set-UserPhoto cmdlet to change their own photo without having to change the
ConnectionUri parameter. However, to change another user's photo, admins must first change the
ConnectionUri parameter. If the parameter isn't changed, admins receive the following error message when they use the cmdlet to change a user's photo:
Request return error with following error message:
The remote server returned an error: (413) Request Entity Too Large...
