Hi Guys,

I have an issue where I haven't been recieving emails and getting the error message about the .ost file and the need to replace.  I 've successfully changed the .ost file and before I've turned the cached exchange mode on again I realised that  I've recieved all the emails.  The problem is that when I turn it back on the emails disappear again.  I'm not sure if there is anything else I need to make changes to.

Thanks

Try starting outlook from the command line once...using the reset folder switch.

GOTO start>run> type> outlook /resetfolders

Also, make sure your showing "online" in the bottom right hand corner of outlook.

If all else fails, delete the exchange profile from your mail settings and put it back in.

I had issues with that in my environment.  We don't really need cached mode b/c we don't have any reason people should ever loose connection.  If you don't need it, uncheck it when setting up the profile.  That solved my problems, which were really getting out of hand up to that point.

Dear expexchuser,

Do you have laptop users at your environment?  If so is the cached exchange mode turned off not affecting them?

No, our data is too sensitive for us to justify laptops and/or wireless.  I can see how this would be a nice feature for those environments, though.  

Regardless, I was going to suggest re-creating the profile to see if that resolves it.  If not, verify where the .ost is pointing (it should be local, not on a network such as might occur with roaming profiles).  If local, maybe try renaming the old one(s) from ***.ost to ***.ost.old and create a new one.  

Also ensure you have installed all the latest office updates.

Have you migrated/reinstalled the exchange server recently (or w/in last several months)?  That was probably the issue I was experiencing (no errrors, just users going offline when they shouldn't and not being able to receive email).  We got new computers in January and didn't have problems with caching until spring.  We migrated our server in April so this article might have applied to me:
