I have a customer whose Outlook 2013 folders on some of her imap accounts started losing emails which were still on the provider's (BT Internet) email server so I assumed a corrupted profile (profile A) and set up a new profile (profile B).
All appeared to be fine until a few days later when emails started disappearing from folders in profile B. However, the difference now was that they were also not on the provider's server (which is what I would expect). How this happened I'm not sure; perhaps the customer deleted them herself inadvertently.
Anyhow, looking at profile A (offline) many of the emails that are now missing in profile B are still in profile A.
My question is, if she opens profile A online, will the provider's server now contain the missing emails AND will it remove emails that are not on profile A (which are present on profile B).
Long term, the plan is to use profile B, but after getting back the missing emails and folders that are still on profile A.
Hope this makes sense!
