AutoComplete Cache in OWA

Copper Contributor

Hello,

is possible for me - as O365 Global admin - clear autocomplete cache in OWA for some user/s? Ideally with Powershell?

 

- or -

 

is possible set OWA to preffer GAL before AutoComplete in suggested address list during composing new message?

 

Situation:

We are renaming all users in whole tenant and want users see new names in suggested list.

 

Thank you

Not with "pure" PowerShell, but you can use an EWS-based script such as the one here: https://gallery.technet.microsoft.com/Clearing-AutoComplete-and-92b8d32a
