Add an option to reset sync tags
After an offline period of 4 weeks, I have a gap of missing mails in my EWS account. It only affects some Foreign Folders Incoming folder, not my main Incoming folder.
Thanks mcrha, I got to resync the missing mails by deleting the column folders.db folders->Foreign..->Incoming, just deleted the bdata cache entry. After restarting Evolution and refreshing the folder, I got the missing mails.
Please investigate how the issue could happen. Please provide a button to force a folder refresh, maybe for the whole account. To be sure I would do such a force refresh every few days now to be sure not loosing any mails.
