I have a user who is experiencing the following error. He is opening an email, clicking reply all, adding some text of his own to the top, and clicking Send. When he does, he gets the following error: "Could not complete the operation. One or more parameter
value are not valid."
He set his .pst file as default data file. This case occured after team deployment to upgrade his laptop from win7 32 bit to be win7 64 bit.
I have done below:
1. Scan and repair pst file by SCANPST.EXE
2. Run Outlook on safe mode
3. Change default data file to ost file
4. Rename ost file, and reload ost file.
5. Disable cached mode (get email by online from server)
No change, he is still getting the error.
Then I delete all TO address list and re-add TO address list or move email to mailbox first, the error is going out.
But the problem still occured while user do repply all, and he must to re-add address or move email to mailbox first.
