I have a user that when she tries to edit her OWA signature, it is greyed out and shows that it is loading but won't allow her to add a signature. She can add one via the mobile app or desktop app but not OWA. When making a settings change and then trying to save, it says:
Couldn't save your signature
If the problem continues, please remove any images and try again.
She used to have a signature set and it never included any images. Additionally, when trying the edit the signature through https://outlook.office365.com/ecp/ it gives her the following error:
error
The value '{"id":"AAMkADIyMTkzNDFjLTJlMjAtNGQ3NC1hMTk5LTc2YTFkOTQxNzk3NAAuAAAAAAA3dABzXGDtS724sFIuV7HeAQAukTveU/f5R4wM3n+PEsjnAAAAAAEpAAA=","type":0}' is already present in the collection.
Any help would be appreciated.
