I’m using MailStore Home on a laptop running Windows 10 Home (fully up-to-date )and had a power failure during a backup.
When I try to start the program I’m now getting the folowing error message :-
MailStore Home was unable to open the archive. Details: Invalid key file format
Looking at the backup folder, everything looks OK apart from the fact that the MailStoreFileGroup.key file is ZERO bytes long.
The actual data backup .dat files look OK as does the MailStoreFileGroup.fdb file.
Looking at other posts, the .key files are (not surpisingly) important and the only other one showing - MailStoreMaster.key is 3 kb in size. For safety reasons I haven’t touched this file.
Is it possible to recreate the MailStoreFileGroup.key file or take any other action which would allow the program to run ?
Any advice wpould be gratefully received.
