Hi I have around 65 users who are getting the error message that:
"If you can see this information, your form cache is probably corrupt, Please clear the form cache."
I have followed the instruction at this link
and that has resolved the issue on the users personal mailbox but the issue still persist on shared mailboxes.
I have also removed the OST file and let it rebuild but this does not resolve the issue.
Any help would be great
Outlook 2016, Windows 7 and Windows 10.
