Did you create the blob with the appropriate type?

@Rich Matheisen , yes , Using above command only , blob is by default getting created with Append typ.

Set-AzStorageBlobContent -Container "data" -File "file" -Blob "$Year/$Month/$Day/status.csv" -Context $context -Force -BlobType Append.

it's updating the logstatus.csv file. but when I am running it again ,it is overwriting old content with new content .ideally it should append.

@Rich Matheisen it is updating now after following this article. https://4sysops.com/archives/create-and-manage-append-blobs-with-powershell/#:~:text=To%20create%20an%20append%20blob%20using%20PowerShell%2C%20we,UPLOAD%20%24storageAccount%20%3D%20Get-AzStorageAccount%20-ResourceGroupName%20AppInsights%20-Name%20forfuncapp

after adding below section to append the blob. just one thing , it is adding column name also with each write operation. any suggestion to remove column name

$contentToAdd = [System.IO.File]::OpenRead("$Status") $blob.BlobBaseClient.AppendBlock($contentToAdd) $contentToAdd.Close()
