Annoyed with the Outook crash on Windows 10 Insider Build !!!
Guess that’s what we can expect with preview software builds, nonetheless until Microsoft figures out the solution for the crash, be sure to lower the threshold of “automatic saving of drafts”
1- Browse to the following setting,
File => Options => Mail => Enable “Automatically save items that have not been saved after this many minutes and set to “1”
2- Set it to 1(default 3)
3- Next time it crashes when you’re in the middle of an e-mail, go straight to your drafts folder and continue
This would just mitigate the data loss to the entries between the last saved checkpoint and the crash.
With bated breathe for a fix … !!!
