What errors do you get when you try to open the .ost file?</P> <P>&nbsp;</P> <P>Regards</P> <P>Ryan</P> Wed, 09 May 2018 15:28:52 GMT RyanJames 2018-05-09T15:28:52Z https://business.forums.bt.com/t5/Email-and-hosting/Can-t-know-how-to-solve-this/m-p/80532#M9946 <P>Pats, I've been searching for a way&nbsp;how to open an ost file. I've been a problem with my .ost in MS Outlook. I can't get access to it from yesterday evening. I have many important messages in this file, unfortunately only two or three days and after I will get huge problems related to my job.</P> Wed, 09 May 2018 13:14:51 GMT https://business.forums.bt.com/t5/Email-and-hosting/Can-t-know-how-to-solve-this/m-p/80532#M9946 evawyatt 2018-05-09T13:14:51Z https://business.forums.bt.com/t5/Email-and-hosting/Can-t-know-how-to-solve-this/m-p/80536#M9947 <P>Hi evawyatt</P> <P>&nbsp;</P> <P>As there is a .ost file, that sounds very much like an Exchange email address - so you could have a Business Apps account with us rather than just a standard email.
