Outlook .ost and opening Outlook offline

Outlook .ost and opening Outlook offline

Outlook .ost and opening Outlook offline

Had an Exchange server. When it crashed we went to Outlook 365. Configured new profiles. One was a laptop. Did not export the original emails and contacts properly before configuring for 365. Have the old .ost file but cannot open Outlook in the old configuration (old profile) to export properly. Pulled the laptop off the network as Outlook did open locally. Now it says you have to be on a network to use the ost the first time. Any suggestions are greatly appreciated.

RE: Outlook .ost and opening Outlook offline

Seems a bit complicated. Let's try anyway.

You can convert the .OST file to .PST with the help of a tool called Remo Convert ost to pst.
The tool just repairs the OST file in the process of converting it to PST. Once the conversion is over, try opening the PST file.

If it turns out to be a disappointment, just don't lose your hope. There are tools provided by Remo to backup and migrate Outlook emails and contacts along with the attributes and settings. Just contact their team and they'll assist you in resolving your problem.

P.S. I've personally tried Remo and hence suggesting it.
