unable to open pst file in outlook 2013

This question has suggested answer(s) This question has suggested answer(s)

I have a user that likes to hold on to email in folders stored in outlook. When we migrated to office 365 online exchange I did a backup of his .pst file.  Once the account was setup on Exchange I did a restore and it appeared to complete. In reality all the folders restored but many are empty. I opened the pst on my outlook 2010 client , it opens and I can see the data in the folders. The user has outlook 2013 and it wont let me open the pst file on his system. The PST file is over 7G but mailbox sizes are supposedly 25GB.

  • Hi nativepdx123,

    In Office 365 Exchange Online, messages have some limitations. Please refer to the following article and make sure the messages in the .pst file do not exceed the limitations.
