Hi ,

we have hybrid exchange setup.

I am using PST capture tool to upload archived email PST data to office365 mailbox.

I am uploading data in archive mailbox.

data upload completes with many error per item

error is "The extended property attribute combination is Invalid" and server could not process request now.

those errors are item specific ,for inbox emails ,when I checked users mailbox those email items skipped from upload.

I tried to re-upload same pst ,resulted in same number of errors and not uploaded those items.

skipped item numbers are very very high.

please suggest how can I fix this.
