Outlook 365 recreates old OST Files all the time - Microsoft Community


hi!

i´m trying desperate find solution on this.

i´m running windows 10 creators update , office 365

ich want create fresh ost profiles mail (imap) accounts.

the reason is, habe problems folders, can´t delete outlook (not via delete, not via imap abo - keep coming back) , not shown in web interface.

so thought, problem must somewhere ost, old folder structrue beeing kept.

for close outlook, move classic mail setup in system control , delete mail accounts , files.

afterwards move folder c:\users\<user>\appdata\local\microsoft\outlook check, if files removed.

afterwards restart outlook , check, if accounts removed. yes, not shown anymore.

but strangely, restart outlook, ost files removed beeing recreated again in folder.

so somehow outlook keeps sourcing them somewhere.

i tried tipp remove registry entrys profiles (deleting: computer\hkey_current_user\software\microsoft\office\16.0\outlook), doesn´t help.

i want build clean folder structure again server, have feeling, problem lies somewhere these osts beeing rebuilded , hanging around in background. if create new profiles, keep staying (they have partially different numbers in end of filename)-

can help? i´m bit desperated, trying find solution since 2 days...

best,

patrick
