Why can't I add multiple signatures in New Outlook anymore?

It looks like this has just been updated. I can only have one signature?
I don't want this, I want a different reply signature to my original signature.
I want a saved signature that I can have for out of office.
I want a saved signature I can have for special occassions.

This update (along with the majority on New Outlook updates) sucks.

The update also deleted all of my signatures that were existing which is very frustrating!

    I am having the exact same issue. We have multiple users in our office under one account and somehow the signatures we had set up disappeared and when trying to re-add multiple signatures the 'add new' or adding additional signatures is no longer available. The new outlook will not allow for more than one signature - it did until today!

    I was Thursday 29th May at 5pm AEST helping one of our customer who is on Business Premium with Outlook on windows machine with 1.2025.522.100 (Production) and was experiencing this issue. We were trying to get her “Book with me” and noticed that web and desktop outlook where out of sync

    My windows/outlook desktop all was on 1.2025.516.400 (Production) and I had no issues.

    Friday 30th May 8am AEST This morning I have done the windows update.
    Now the inconsisency is that on my recently updated signatures are now syncing correctly with 1.2025.516.400 (Production) - Arghh
