It looks as though there may be some corruption in the mailbox.
Can you try with one user, exporting all the mail/calendar/contacts to PST using Outlook delete the mailbox and re-create it then re-import the mail.

Then try again and see if it works.

I will have a go at close of business today, my only concern is that there are quite a few users within the organisation that have this issue and I really don't want to have to do this for 40 or so mailboxes.

It's worth just checking if it fixes it.

tried this and it worked but rather than doind this for all the corrupt mailboxes I ran ISINTEG, all working fine now so thank you for pointing me in the right direction of corruption!
