I have a user who is receiving the following messages when archiving either manually or through auto-archive:
Error while archiving folder "Sent Items" in store "<Users E-mail account>". Access is denied. Verify the disk is not full or write-protected and that the file is not being used.
The above error is repeated for each folder in Outlook (Inbox, All sub-folders of Inbox etc...)
I've checked permissions on both the .ost file (Running in cached exchange mode) and the .pst file that is being used to archive to and the user account has full access to both.
Any ideas before I just try and rebuild a new Outlook profile for the user?
