Error importing Autocomplete Message

[Strionat]

Hi,
today I used your wonderful app to import autocomplete list in a bunch of Outlook clients whose mailbox was migrated to 365.

Everything went fine but one import failed with the following error code:

Error:
Code: STG_E_SHAREVIOLATION == 0x80030020
Function MyStgOpenStorage(szMessageFile, true, &pStorage)
File D:\a\1\s\core\mapi\mapiFile.cpp
Line 50

I tried to export and import the list again but every time it failed with this error.

Thank you

Strionat
