Using Classic Outlook on Windows for personal email, calendar, and contact management
I dont use templates. I do use signatures.
Small single user business with 1 x exchange email account , with multiple sub-addresses (admin@ hello@ records@ etc)
The pop up ONLY appears after changing the email address in From field - for replies/new emails/forwarding
Each email address has a different signature attached to it.
I also have a gmail account in my outlook profile. The pop up DOES NOT appear if changing From field from my gmail account to one of my exchange account email addresses.
It does occur if changing the From field from my gmail address back to an exchange email address
Rebooting/restarting Outlook has no impact.
No encryption is used
Occurs identical pattern on two computers - 1 x win11 , 1 x win10
Outlook 365 is set up fairly similar on both - same 2 email accounts (gmail & exchange)
Different add-ins on the 2 computers - one has Microsoft exchange & Zoom (only)
the other has MS Exchange, MS Sharepoint server colleague..., OneNote Notes, Outlook social connector
Many thanks for investigating
